A.1.1 Calculation

This column has the options which control how nip2 starts and how and when it calculates.

Data path

This is a list of directories where nip2 searches for data files. These are any files that nip2 can use but which aren't loaded at startup. I usually append the main areas on my machine where I store image files, for example.

The default value is ["$HOME/.$PACKAGE-$VERSION/data", "$VIPSHOME/share/nip/data", "."].

Temporary files

This is where any intermediate files will be stored. It defaults to a directory called tmp under your home area's .nip2-xx directory. If nip crashes, it may leave old files here.

Start path

This lists directories which are searched when nip2 starts for any loadable files. Anything that nip2 comes across will be loaded up.

The default value is ["$HOME/.$PACKAGE-$VERSION/start", "$VIPSHOME/share/nip/start"].

Auto-recalc

With this on (the default) nip2 will recalculate whenever anything changes. Turn this off if recalculations are taking a long time and you want to make a series of small changes.

Update sliders during drag

This sets whether recalculation happens as sliders are dragged, or whether the recalculation waits until the drag finishes. There's a similar setting for regions.

Auto workspace save

With this tured on (the default) nip2 will save the current workspace to the temporary files area a second after the last recalculation. If nip2 crashes, you can restart it and click File / Recover after crash and nip2 will reload the last workspace where you made a change.

Auto-reload on file change

With this tured on nip2 will automatically reload any image files that change while it has them open. Handy if you're using nip2 to watch a file that another program is updating.

Maximum text display

This sets the number of characters nip2 shows for string values. Turn it up if you want to see inside long strings.

Maximum heap

This sets the limit on the heap size. Turn it up if you start getting Heap full error messages. If you left-click on the space free label in the bottom right of the main window, it will change to display the current heap statistics. There's a useful tooltip as well.

Number of CPUs to use

If you have a machine with more than one CPU, you can make nip2 faster by upping this number.
