VIPS/NIP is actually two things... one is a library, and one is a
sample application built on it. I never remember which is which. I found
it about 2 years ago as I was trying to find an image editor for linux
with >8bpp. They are self-proclaimed "cross between Photoshop and Excel."
Very odd interface that I never quite got used to. It has potential for
weird image formats and "spreadsheet-like" batch processing.
Cinepaint (formerly known as film-gimp) has a web-page describing
some of their history. I think it requires a library that deals with (and
describes) some of the funkier formats that were developed for
high-dynamic-range CG image processing.
I don't remember too much of the details and I'm away from
broadband for the day... :)
