Actually, the link that started this post is a link to a wavelet compression
util. :-)
As for the FIF format, I have several viewers that can handle it, and I once had
a writer, sadly enough it was lost a looong time ago(four or five reformats...)
and, I wasn't working ON the FIF project, I was working with the FIF compressor,
and reading up on the algorithm. It was back when I liked doing demos, and I
madee some implementations of it with edge detection(didn't work for many
images) and trying to find a fractal match(Brute force). Needless to say, I
didn't succeed at all.. *hehe*
As for format definitions, I don't know whether it is public or if it is
licenced in some way. It would be nice to see it public(Bye bye JPEGS).
