My lazyness :-). Anyway they are not so frequent. This comes from pre-ICC age, and AFAIK there are very few TIFF readers supporting that. Today is easier just embed the corresponding ICC profile. It takes same disk space and many apps honors the profile. I will try to add the code for 1.14. Do you have any samples of such TIFFs? Just to make sure it works as expected... > The next question is about gray profiles and gamma. Does lcms assume > gamma 2.2 for PT_GRAY->PT_RGB? The kTRC tag of the input profile has > gamma = 1.0 . Well, lcms does use kTRC on gray profiles, this is how they work. The gamma should be 1.0 in that case. But then the input profile should be marked as monochrome, not RGB.
