Hello Robin,
your suggested patch appears very small.
In the past the input and output data structure members of the colour
transforms where not part of a suggestedly stable public API. lcms
had many non so stable APIs marked with a underscore. At least to me this
appeared always clear. And I avoid as good as possible these APIs.
One other alternative way to provide the functionality as in your patch is
to add a wrapper around lcms' cmsHTRANSFORM, like
struct lcms_wrapper {
objectType type;
cmsHTRANSFORM xform;
cmsHPROFILE profile_array[];
int profile_count;
int intent;
int intent_proofing;
int flags;
... /* more as you like and need */
};
kind regards
Kai-Uwe Behrmann
