Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described

value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and

<resource file>.
These resources have
higher priority than those provided

.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the

may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec

.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the

Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1

Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>

gv). Executing the script and thereby creating a new

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi

.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).

of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,

The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp

relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource

.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

.IP "-antialias, -noantialias"
.nr bi 1

.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

If -nodsc is used gv will not attempt to examine
the structure of

This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"

.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end

comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as

.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.

automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap

at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,

with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.

the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

bi 1
.Pp
Determines whether ghostscript should be started with the
"-dQUIET"
command line option.
.IP "gsArguments"
.nr bi 1
.Pp
May be used to provide
additional command line options for the
ghostscript interpreter.
Starting
gv with the "-arguments <arguments>"

The default values listed above provide examples
for this syntax.
"screen" will automatically be replaced by the size of
the
screen.
.IP "minimumWidth, minimumHeight"
.nr bi 1
.Pp
Defines a minimum
size for the main window.
Valid values for both resources are positive integers
larger
than 200.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and

<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1

Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,

.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

by providing a user interface for the ghostscript
interpreter.

.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).

periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0

.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the

When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr

.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from

.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource

.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to

landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into

at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit

.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size

automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS

,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi

Note that this method doesn't work on VMS.

the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi

may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and

by providing a user interface for the ghostscript
interpreter.

Please note that gv is derived from Tim Theisen's

1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2

.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the

does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource

.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and

<resource file>.
These resources have
higher priority than those provided

.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "

number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"

.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).

Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr

.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource

.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1

<resource file>.
These resources have
higher priority than those provided

.IP "-antialias, -noantialias"
.nr bi 1
.Pp

the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1

.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr

.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

.IP "-antialias, -noantialias"
.nr bi 1

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

If the value of this resource is "False" the X Server is advised that
saving off-screen pixels of the displayed page would be beneficial (maintaining
backing store). In this case gv does not actively maintain the contents
of the page but relies on the X Server. The server is, however, always free
to stop maintaining backing backing store. If the value of this resource
is "True" the X Server is advised that maintaining backing store is not
useful. In this case gv attempts to allocate a sufficiently large pixmap
to store the contents of the displayed page.

are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource

.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp

.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.

tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.

It is probably a de facto standard for user interfaces

However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from

.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.

This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"

periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or

Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the

<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"

Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit

.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS

may be added to a resource file read by gv. Here

,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi

Note that this method doesn't work on VMS.

the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi

may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"

.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

.IP "-antialias, -noantialias"
.nr bi 1

.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and

<resource file>.
These resources have
higher priority than those provided

.IP "-antialias, -noantialias"
.nr bi 1

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the

does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or

Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the

<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"

Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

The default values listed above provide examples
for this syntax.
"screen" will automatically be replaced by the size of
the
screen.
.IP "minimumWidth, minimumHeight"
.nr bi 1
.Pp
Defines a minimum
size for the main window.
Valid values for both resources are positive integers
larger
than 200.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1

Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).

periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr

.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and

"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0

.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.

may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1

.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"

.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1

Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

of this resource is the offset
of the scale to be selected relative to
the scale 1.0 in the
the "Scale" menu.
.IP "scaleBase"
.nr bi 1
.Pp
Selects
the initial scale base. The value of this resource should
be a positive
integer.

.IP "orientation"
.nr bi 1
.Pp
Sets the initial orientation.
Valid values are
"portrait", "landscape","seascape",
"upside-down" and
"automatic".
"automatic"
causes gv to attempt

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.

tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,

automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript
and PDF documents on an X display
by providing a user interface for the
ghostscript interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291

.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and navigate through
PostScript
and PDF documents on an X display
by providing a user interface for the
ghostscript interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".

.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Please note that gv
is derived from Tim Theisen's

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript and

by providing a user interface for the ghostscript
interpreter.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf

a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x

.DE
.fi

may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and

<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript and

.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

.IP "-antialias, -noantialias"
.nr bi 1

.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp

.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new

in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the

and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1
.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource

.IP "-antialias, -noantialias"
.nr bi 1

.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the

.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.Pp
Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1

Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".

a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into

a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr

.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will

depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing

By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr

.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP

.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.

.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp

a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp

the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

When viewing a document at a relative scale of 1.0 using the "Natural size"
base the page should appear in its real size, as if printed on paper. For
the "Natural size" base to work properly gv has to know the correct size
of the root window. Automatic detection of this size unfortunately only
provides approximate results, therefore it is best if it is provided by
the user. To do so the resource
GV.screenSize: <width> x <height>
should be added to the "SCREEN_RESOURCES" property of the screen the
document is viewed on, with <width> and <height> describing the width and height
of the root window in units of millimeters. For instance by using the command
echo "GV.screenSize: 396 x 291" | xrdb -override -screen
a width of 346 mm and a height of 291 mm will be used for the "Natural
size" scale base. Alternatively the resource
GV.screenSize_<machine>_<disp>_<scr>: <width> x <height>
may be added to a resource file read by gv. Here <machine> ,<disp> and ANGLED)
describe the display on which gv displays the document. For instance, if
the display is set to "tic.tac.toe.wo:0.1" the resource should be specified
as
GV.screenSize_tic_0_1: 396 x 291
Note that this method doesn't work on VMS. As a last alternative the resource
GV.screenSize: <width> x <height>
may be added to one of the resource files. However, for obvious reasons
this method should be used only on single user machines. 1

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

depend on any external resource files.
However, when starting gv, preferences
are read from

.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.

.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1

a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local

The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options

.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.

Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"

would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp

<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P

Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec

P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1

a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE

.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.

"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP

.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"
.nr bi 1

Determines
whether gv should attempt to respect document
structuring comments.
Valid
values are "True" and "False".
.IP "reverseScrolling"
.nr bi 1
.Pp
Defines
the interpretation of directions when
scrolling with the mouse.
Valid values
are "True" and "False".
.IP "swapLandscape"
.nr bi 1
.Pp
Whether the meaning
of "landscape" and "seacape"
should be interchanged.
Valid values are "True"
and "False".
.IP "scratchDir"
.nr bi 1
.Pp
Specifies a directory used to store
temporary data.
.IP "defaultSaveDir"
.nr bi 1
.Pp
Specifies the default destination
directory for files to be saved.
.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit

.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp

Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr

.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

Description
.Pp
.Pp
gv allows to view and navigate through
PostScript and
PDF documents on an X display
by providing a user interface for the ghostscript
interpreter.
.Pp
Please note that gv is derived from Tim Theisen's
ghostview
1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr
bi 1
.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr
bi 1
.Pp
Whether to use antialiasing.
.IP "-arguments <arguments>"
.nr bi 1
.Pp
Start
ghostscript with additional options as specified by the
string <arguments>.
.IP
"-center, -nocenter"
.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.
Valid values are "True" and "False".
.IP "confirmPrint"
.nr bi 1
.Pp
Whether
printing requires an extra confirmation.
Valid values are "True" and "False".
.IP
"confirmQuit"
.nr bi 1
.Pp
Whether leaving gv requires extra confirmation.
Valid
values are "0" (Never), "1"
(When processing) and "2" (Always).
The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.
Valid
values are "True" and "False".
.IP "respectDSC"

.IP "useBackingPixmap"
.nr bi 1
.Pp
If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.
.IP "watchFile"
.nr bi 1
.Pp
Whether the document should be checked periodically
and updated
automatically if changes are detected.
Valid values are "True"

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.Pp
The name of the file to be displayed.
The file ending ".ps" may be
omitted.
"filename" may point to a compressed file
(gzipped, zipped or
compressed).
Viewing PDF files requires at least ghostscript version 4.x.
.IP
"-ad <resource file>"
.nr bi 1
.Pp
Read and use additional resources from the
file
<resource file>.
These resources have higher priority than those provided
in
the context of the -style <resource file> option.
.IP "-antialias, -noantialias"
.nr

.nr bi 1
.Pp
Whether the page should be centered automatically.
.IP
"-dsc, -nodsc"
.nr bi 1
.Pp
Determines if document structuring convention (DSC)
comments
should be respected or ignored.
If -nodsc is used gv will not attempt
to examine
the structure of the document but will pass the file
to the
ghostscript interpreter as a whole. In this case no page numbers
are shown
and freely moving around in the document is not possible.
This option may
help when viewing files not conforming
to the document structuring conventions.
.IP
"-eof, -noeof"
.nr bi 1
.Pp
Defines the behaviour of the postscript scanner
used to
examine the structure of the document.
If -noeof is used the scanner
will ignore end of file (EOF)
comments. This may help when viewing documents
which import other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr

.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.

.SH Description
.Pp
.Pp
gv allows to view and
navigate through
PostScript and PDF documents on an X display
by providing
a user interface for the ghostscript interpreter.
.Pp
Please note that gv
is derived from Tim Theisen's
ghostview 1.5.
.Pp
.SH Options
.Pp
.nr ll +1
.nr
tn(ll 2
.if n(ll>1 .RS
.IP "filename"
.nr bi 1
.Pp
The name of the file to be
displayed.
The file ending ".ps" may be omitted.
"filename" may point to a
compressed file
(gzipped, zipped or compressed).
Viewing PDF files requires
at least ghostscript version 4.x.
.IP "-ad <resource file>"
.nr bi 1
.Pp
Read and
use additional resources from the file
<resource file>.
These resources have
higher priority than those provided
in the context of the -style <resource
file> option.
.IP "-antialias, -noantialias"
.nr bi 1
.Pp
Whether to use antialiasing.
.IP
"-arguments <arguments>"
.nr bi 1
.Pp
Start ghostscript with additional options
as specified by the
string <arguments>.
.IP "-center, -nocenter"
.nr bi 1
.Pp
Whether
the page should be centered automatically.
.IP "-dsc, -nodsc"
.nr bi 1
.Pp
Determines
if document structuring convention (DSC) comments
should be respected or
ignored.
If -nodsc is used gv will not attempt to examine
the structure of
the document but will pass the file
to the ghostscript interpreter as a
whole. In this case no page numbers
are shown and freely moving around in
the document is not possible.
This option may help when viewing files not
conforming
to the document structuring conventions.
.IP "-eof, -noeof"
.nr bi
1
.Pp
Defines the behaviour of the postscript scanner used to
examine the
structure of the document.
If -noeof is used the scanner will ignore end
of file (EOF)
comments. This may help when viewing documents which import
other
documents without enclosing them within the proper
"BeginDocument"
and "EndDocument" comments.
If -eof is used, the scanner treats an EOF comment
as
marking the end of the file.
.IP "-pixmap, -nopixmap"
.nr bi 1
.Pp
If -pixmap
is used gv tries to maintain off-screen regions
of the displayed page by
allocating a sufficiently large pixmap.
If -nopixmap is used the X Server
is responsible for
maintaining obscured portions of the displayed page
(see
also the "useBackingPixmap" resource).
.IP "-v "
.nr bi 1
.Pp
Print the version
number of gv to standard output and exit.
.IP "-h, -? "
.nr bi 1
.Pp
Display
a short help message and exit.
.IP "-help"
.nr bi 1
.Pp
Display a more explicit
help message and exit.
.IP "-scale <n>"
.nr bi 1
.Pp
Selects the scale entry <n>
relative to the scale 1.0.
<n> must be an integer.
.IP "-scalebase <n>"
.nr bi 1
.Pp
Selects
the scale base <n>.
.IP "-monochrome, -grayscale, -color"
.nr bi 1
.Pp
Sets the
color palette to be used.
.IP "-media <media>"
.nr bi 1
.Pp
Selects the paper
size to be used. Valid values are names of
paper sizes that appear in the
list of page medias as given
by the medias resource.
.IP "-page <label>"
.nr
bi 1
.Pp
Display the page with label <label> first.
.IP "-portrait, -landscape,
-seascape, -upsidedown"
.nr bi 1
.Pp
Sets the orientation.
.IP "-quiet, -noquiet"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dQUIET option.
.IP "-resize,
-noresize"
.nr bi 1
.Pp
Whether gv is allowed to automatically fit the
size
of its window to the size of the displayed page.
.IP "-safer, -nosafer"
.nr
bi 1
.Pp
Whether to start ghostscript with the -dSAFER option.
.IP "-spartan"
.nr
bi 1
.Pp
This is a shortcut for "-style gv_spartan.dat".
.IP "-style <resource
file>"
.nr bi 1
.Pp
Read and use additional resources from the file <resource
file>.
These resources have lower priority than those provided
in the context
of the -ad <resource file> option.
.IP "-swap, -noswap"
.nr bi 1
.Pp
Whether to
interchange the meaning of the orientations
landscape and seascape.
.IP "-watch,
-nowatch"
.nr bi 1
.Pp
The -watch option causes gv to check the document
periodically.
If changes are detected gv will
automatically display the newer version
of the file.
The document is by default checked once every second.
This
can be changed via the watchFileFrequency resource.
Note that sending gv
the SIGHUP signal also causes
an update of the displayed document. This
method
may be used by document creators to trigger gv
remotely.

Resource files
.Pp
In general gv does not
depend on any external resource files.
However, when starting gv, preferences
are read from
.Pp
.nr ll +1
.nr tn(ll 0
.if n(ll>1 .RS
.nr bi 1
.Pp
a system specific
resource file.
The name of this file is as described by the "XFILESEARCHPATH"
environment
variable, or, if this variable is not defined,
implementation dependent.
In most cases it is
"/usr/X11/lib/X11/app-defaults/GV".
Administrators
may want to modify this file in order
to set up gv according to the local
needs of their system.
.nr bi 1
.Pp
a user specific resource file.
The name
of this file is either "~/.gv" or as described
by the "XUSERFILESEARCHPATH"
environment variable.
.if n(ll>1 .RE
.nr ll -1
.Pp
The files "gv_user.ad" and "gv_system.ad"
(located in the library directory
of gv, which is most probably either
"/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis
for constructing
the user and system specific resource files.
.Pp
Note that the user and system
specific resource files are not the only
sources of preferences taken into
account when gv is started.
However, in practice these are the most important.
.Pp
Resources
of gv
.Pp
The following describes some of the resources of gv.
The precise
syntax of some of the resource values may be
inferred from the appended
default system specific resource file.
.Pp
.nr ll +1
.nr tn(ll 2
.if n(ll>1 .RS
.IP
"antialias"
.nr bi 1
.Pp
Whether antialiasing should be used.
Valid values
are "True" and "False".
.IP "autoCenter"
.nr bi 1
.Pp
Whether the displayed
page should automatically be centered
(for instance when opening a new
file).
Valid values are "True" and "False".
.IP "autoResize"
.nr bi 1
.Pp
Whether
gv is allowed to resize the main window
according to the size of the current
page.

The default
value is "1", which causes
a confirmation request when trying to leave
gv
in the presence of pending PDF to Postscript conversions.
.IP "scrollingEyeGuide"
.nr
bi 1
.Pp
If this resource is "True" scrolling via the
keyboard causes a
temporary border to be drawn around the
previously visible area of the
page.
Allowed values are "True" and "False".
.IP "ignoreEOF"
.nr bi 1
.Pp
Defines
the behaviour of the postscript scanner as described
in the Options section.

If the
value of this resource is "False" the X Server
is advised that saving off-screen
pixels of the displayed page
would be beneficial (maintaining backing store).
In this case gv
does not actively maintain the contents of the page but
relies
on the X Server. The server is, however, always free to stop
maintaining
backing backing store.
If the value of this resource is "True" the X Server
is
advised that maintaining backing store is not useful.
In this case gv attempts
to allocate a sufficiently large pixmap
to store the contents of the displayed
page.

.IP "Scales"
.nr bi 1
.Pp
The "Scale" menu which allows to view the
document
at different sizes is divided into two parts. The first part
shows
a list of available scale bases, the second part,
separated by a line,
lists the relative scales which are applied
with respect to the selected
scale base.
.Pp
By default two scales bases are available, the "Natural size"
and
the "Pixel based" base.
When choosing the "Pixel based" scale base a relative
scale
of 1.0 causes one postscript point to correspond to one pixel on
the
screen.
.Pp
When viewing a document at a relative scale of 1.0
using
the "Natural size" base the page should appear in its
real size, as if
printed on paper.
For the "Natural size" base to work properly gv has to
know
the correct size of the root window. Automatic detection
of this size
unfortunately only provides approximate results, therefore
it is best if
it is provided by the user. To do so the resource
.DS
.sp
.ft RR
.nf
GV.screenSize:
<width> x <height>
.DE
.fi
.ec
.ft P
.sp
should be added to the "SCREEN_RESOURCES"
property of the screen
the document is viewed on, with <width> and <height>
describing
the width and height of the root window in units of millimeters.
For instance
by using the command
.DS
.sp
.ft RR
.nf
echo "GV.screenSize: 396 x 291"
| xrdb -override -screen
.DE
.fi
.ec
.ft P
.sp
a width of 346 mm and a height
of 291 mm will be used for the
"Natural size" scale base.
Alternatively
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize_<machine>_<disp>_<scr>: <width> x
<height>
.DE
.fi
.ec
.ft P
.sp
may be added to a resource file read by gv. Here
<machine>
,<disp> and ANGLED) describe
the display on which gv displays the document.
For
instance, if the display is set to "tic.tac.toe.wo:0.1"
the resource should
be specified as
.DS
.sp
.ft RR
.nf
GV.screenSize_tic_0_1: 396 x 291
.DE
.fi
.ec
.ft P
.sp
Note that this method doesn't work on VMS.
As a last alternative
the resource
.DS
.sp
.ft RR
.nf
GV.screenSize: <width> x <height>
.DE
.fi
.ec
.ft
P
.sp
may be added to one of the resource files. However, for obvious reasons
this
method should be used only on single user machines.
.Pp
.IP "Scrolling"
.nr
bi 1
.Pp
It is probably a de facto standard for user interfaces
that windows
are supposed to be scrolled by means of
scrollbars attached to their sides.
However,
for various reasons the use of scrollbars
has been minimized in gv.
.Pp
Instead,
in all windows with obscured data, scrolling
may be performed by
pressing
button1, moving the mouse, then releasing button1
directly in the window.
This includes the displayed page,
zoom popups, the table of contents and
the file and
directory lists displayed in the file selection popup.
.Pp
.IP
"Displaying new versions of a document"
.nr bi 1
.Pp
During document creation
it is usually desirable to
always display the newest version of the document
in work.
.Pp
Instead of explicitly loading it via the file selection
popup
the most recent version can be displayed by
pressing the "Redisplay" button
in the main window
(VMS users should use the "Update File" entry in the
"File"
menu).
Choosing the "Redisplay" entry in the menu that pops
up when clicking
with the third mouse button anywhere on the
displayed page certainly has
the same effect.
.Pp
More comfortable is the "Watch File" feature which may
be
switched on by selecting the corresponding entry in the
"State" menu. If
activated gv will check
every now and then if a new version of the displayed
file
exists. If so it will be displayed automatically.
By default the file is
checked about once every
second.
.Pp
Finally it may also be left to the document
creating program
to trigger gv to update its display. To do so the
program
should send the SIGHUP signal to gv.
For instance at the end of a shell
script generating a
postscript file from latex sources the line
.DS
.sp
.ft
RR
.nf
kill -SIGHUP <gv_pid>
.DE
.fi
.ec
.ft P
.sp
may be added (here CR<gv_pid>
is the process id of
gv). Executing the script and thereby creating a new
version
of the document will then also cause the
result to be displayed instantaneously.
Please
note that this feature is available only on X11 R6
based systems.
