[Lcms-user] Emulating Adobe's color engine

[Esben Høgh-R. M. <eh...@ph...>]

Hi everyone,

I am considering a feature I think could be useful for others and is thinking about the easiest way to implement.

The Adobe color engine has the annoying quirk that it limits the slope of the transfer function for pure gamma profiles. They spill the beans in "Annex C: implementation notes (Informative)" in the specification of the Adobe1998 color space.

Since a disturbingly large fraction of the world consider Adobe products to be the standard of color management, it would be useful to have an option that emulates this behavior. My plan is to look at the tag and replace the curve with a computed look-up table in this case.

This does not strike me as particularly elegant, so I would just ask whether there is a better way to attain the same goal.

Kind regards,
