nip2 --- a user interface for libvips
nip2 is a GUI for the libvips 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 page. If you have to build from source, see the section below.
nip2 comes with a 50-page manual --- press F1 or Help / Contents in the program to view it.
