Click on the Edit / Preferences to see all the preference
options. There are a lot of things you can change (probably
too many). This section will list the most important.
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 / Search for WorkspaceBackups and nip2 will reload the last workspace
where you made a change.
Auto-reload on file change
With this turned 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.
A.0.2 Image display
This set of options control the default image display
window settings. Useful if you’re always having to turn the
status bar on (for example). The maximum size option is
handy if you’re using nip2 on a machine with a small
display.
The Auto popup option makes nip2 pop up an image
display window automatically whenever you make a new
image object.
A.0.3 Other options
Other areas of preferences are less useful.
Display LEDs
If you’re using a theme which uses bitmaps for
widgets, you won’t be able to see the button colour
changes nip2 usually uses to indicate state. This
option adds three small LEDs to each row which
indicate select, busy and error.
Default image format
By default nip2 file browsers show only VIPS
images. If you find you mostly use (for example)
JPEG images, you’ll save yourself a few clicks
on every file operation by switching this option to
JPEG format.
Image format options
You can set the save options for the various image
formats.
Video for linux
If you running Linux and have a capture card
that supports the V4L interface, you can capture
straight from the card into nip2. Set the capture
options here.
Paintbox
The paintbox normally tracks all undo operations.
This can chew up a lot of memory, especially for
flood fills. Reduce the number of undo steps to free
up some RAM.
