Ipe user macros
Ipe user macros make it possible to extend Ipe with new
functions. Ipe user macros, or Iums for short, are simply
programs that read and write files containing a description of Ipe
objects. By listing them in Ipe's X resources, you can make
them known to Ipe. When this is done, they can be called just like
any other function of Ipe. You can even have keyboard shortcuts for
Iums.
Ipe comes with a small set of useful Iums that perform functions
that are not so often used or are too complicated to put into the
Ipe kernel. These functions are described in this section.
Furthermore, we describe how the interface between Ipe and its user
macros works, and how you can write you own Ipe user macros.
Many other Ipe user macros can be found at the world wide Ium
home page. These user
macros have been written by Ipe users for Ipe users, and if you write
other interesting Ipe user macros, it would be nice if you shared them
with us.
