nip2 - a user interface for the VIPS image processing library
nip2 is a GUI for the VIPS image processing
library. It's a little like a spreadsheet:
you create a set of formula connecting your objects together, and on a change
nip2 recalculates.
You can probably install nip2 via your package manager. For
Windows and OS X, you can download a binary from the nip2 releases
area. Only read on if you want to
compile yourself from source.
Documentation
nip2 comes with a 50-page manual --- press F1 or Help / Contents in the
program to view it.
Building nip2 from source
In the nip2 directory you should just be able to do:
$ ./configure
$ make
$ sudo make install
By default this will install files to /usr/local.
See the Dependencies section below for a list of the things that
nip2 needs in order to be able to build.
If you downloaded from GIT you'll need:
$ ./autogen.sh
first to build the configure system.
Dependencies
nip2 needs vips, gtk2 and libxml2 at runtime and flex/bison at compile time.
If you have fftw3, gsl, goffice, libgvc you get extra optional, but useful,
features.
Tips
production build with
./configure --prefix=/home/john/vips
debug build with
CFLAGS="-g -Wall" ./configure --prefix=/home/john/vips
(--enable-debug turns on and off automatically with development / production
minor version numbers)
leak check
export G_DEBUG=gc-friendly
export G_SLICE=always-malloc
valgrind --suppressions=/home/john/nip2.supp \
--leak-check=yes \
nip2 ... > nip2-vg.log 2>&1
memory access check
valgrind --suppressions=/home/john/nip2.supp \
--leak-check=no --db-attach=yes \
nip2 ... > nip2-vg.log 2>&1
or put "--suppressions=/home/john/nip2.supp" into ~/.valgrindrc
profiling
valgrind --tool=callgrind \
--suppressions=/home/john/nip2.supp \
nip2 ... > nip2-vg.log 2>&1
