I give up. You don't hear me say that often. I have studied the (GPL) GIMP code and had some useful exchanges with GIMP developers on the question of how to better fit full color into 256 colors. It's still possible that a little more work would get it, but
(a) we can't just clone the GPL GIMP code into LGPL Jmol, (b) the algorithms for "finding the nearest color" are quite complex, (c) the algorithms for "sharing the error" are much more obtuse than a first look would suggest, (d) the pay off - very large but nice-looking animated GIF files - is not large enough in my opinion, particularly since GIMP does this already, and (e) I just don't have the time to devote to this. So if someone else wants to give this a try, great, but it must be a new idea, not a straight or even slightly modified implementation of GIMP. Clearly these folks have done a spectacular job. And that work is protected by GPL which is not compatible with Jmol's LGPL license. What I can do is provide a PNG option for the CAPTURE command. That's easy enough. Then let other packages put those together into movie files. Bob -- Robert M.
