I'm looking for information on how to quickly generate an inverse palette (see Inside Mac V-137 for a discussion of inverse palettes). Using the brute force method, with lots of optimization and common sub-expression work, the best I've been able to do is 1.5 minutes on an 8 MhZ 286 (this is for a 15 bit (5x5x5) inverse palette); which is way slower than the Mac toolbox can do it. Therefore I'm assuming there's a better algorithm (I've thought about "growing" the inverse palette, similar to a seed fill, but I can't see how this will be any faster (and it would certainly require lots of memory)). I've already looked at PBMPLUS, it doesn't build an inverse palette. marcos -- Marcos H.
