You can embed anything you like in any kind of TIFF; just remembering that other applications will likely not understand how to read itŠ

A TIFF file does not have a sample format, just the image(s) within.

I'm wondering if there is a way to embed a lookup table in a floating point (SAMPLEFORMAT_IEEEFP) tif file? It would seem that the required lookup table size for a 32bit value is 2^32, which is gigantic! The way I expect this to work is to apply the lookup between the values set by MinSampleValue\MaxSampleValue or SMinSampleValue\SMaxSampleValue

A week ago I asked this question on SO

but it hasn't received much of a response. Maybe somebody on this mailing list would know?
