> Yes, that is fine. But there are no standard compression algorithms, > more specifically, no popular decompression algorithms, that do it. There are a lot of papers about palette-based compression. Most of the research beats JBIG by a margin in it's own territory, b/w in the end is just a two-color palette. In your three color case, if you have no better inspiration, just code two planes (a: is it color 0 or the others?, b: is it colour 1 or the others?, c: is implicit). Ciao Niels
