I am creating a transform with cmsCreateProofingTransform(Lab_profile, TYPE_LabA_FLT, output_profile, TYPE_RGBA_FLT, softproof_profile, out_intent, INTENT_RELATIVE_COLORIMETRIC, cmsFLAGS_SOFTPROOFING | cmsFLAGS_NOCACHE | cmsFLAGS_BLACKPOINTCOMPENSATION); and use that later with cmsDoTransform() > What result do you expect?

With the profile with a parametric tonecurve (sRGB in my example, but there are others, too) the use of softproofing doesn't affect the image at all. It still looks the same as when no softproofing is enabled. Other profiles used the same way work though. > This would > help to catch the bug if this is the case It might very well a bug on my side. > Thanks > Marti Tobias > On Jun 20, 2016 12:19 PM, Tobias Ellinghaus <m...@houz.org> wrote: > > Hello, > > > > I am currently struggling to use a profile with a parametric tone curve > > for > > softproofing.
