Thanks for the pointers, I actually got it all pretty much working by the time of your post. The only things that I haven't been able to find equivalents for are the cmsTakeIluminant(...) & cmsBuildRGB2XYZtransferMatrix(...). In place of cmsTakeIluminant(...) I'm just using cmsD50_XYZ() as the docs from LCMS 1 state:
----------------- Notes: ICC states that profile illuminants MUST be D50. However, in real world, each manufacturer uses an illuminant value that differs slightly of D50. lcms takes this variation in account and does the necessary scaling. ----------------- So it would be nice to get the Illuminant from the profile but I don't see how that's possible in LCMS 2. As for cmsBuildRGB2XYZtransferMatrix(...), I'm currently just including <lcms2_internal.h> where needed and using the now private _cmsBuildRGB2XYZtransferMatrix(...). Yeah, I know, we shouldn't be using the private API but it wasn't private before. ;-) Any reason why that's no longer exported?
