Hello Udi, you are right a mixing of profiles in a chain together with a proofing profile has not an own function. Nethertheless there are some workarounds possible.
You may basically create a cmsCreateMultiprofileTransform, convert to a device link with cmsTransform2DeviceLink and use this in the proofing transform with cmsCreateProofingTransform. For a working example you could look at the CinePaint code. It may help you a bit further: app/cms.c cms_create_transform(). kind regards Kai-Uwe Behrmann -- development for color management www.behrmann.name + www.oyranos.org + www.cinepaint.org Am 29.01.07, 00:22 +0100 schrieb Udi Fuchs: > Hi, > > I'm trying to implement a proofing profile option into UFRaw, but > there seem to be some missing functionality in lcms. > > At the moment the user can choose an input profile and an output > profile.
