Hey about the palette and some notion of compressing the palette, I thought one method that was in use was to compress the ColorMap with LZW, and then when the library gets the ColorMap, if its number of elements doesn't match the SamplesPerPixel/PhotometricInterpretation/ExtraSamples/Indexed indicated correct value for the count of elements of the ColorMap, then it is uncompressed transparently for the ColorMap access.

Any official source on that? It seems like info I might want to add to the ColorMap tag page, if it's semi- or de-facto-standard, so have you got any pointers to share on that subject?
