Right. I couldn't find any of the pre-supplied parametric curves that would work. I did find some commented out code in testbed/testcms2.c for a custom Rec. 709 curve. I've tried to use the modified code in colord, but it threw some errors: LCMS error 8: Unsupported parametric curve LCMS error 7: Couldn't write type 'para' LCMS error 8: Unsupported parametric curve LCMS error 7: Couldn't write type 'para' I've attached the patch for colord that I've tried. I *think* I'm registering the plugin correctly, but I've never done an lcms plugin before. It might be I'm doing something batshit-insane, in which case I'd appreciate some clue. :) Thanks, Richard.
