Just some notes for anyone thinking about implementing some of this: Black point compensation is not a part of the ICC specification and is not currently available in any icc library that I know of. Use paper white: requires ink black to be on also. Use an absolute colorimetric transform. Use ink black: I belive this option would be pretty simular to using an absolute colorimetric transform for the shadow, and a relative colorimetric transform for the highlight. I know this is possible with the argyll cms library, but I'm not sure about any others. (see the -w option to icclink) Neither ink black or paper white is on: Use a relative colorimetric transform. IMHO: Rather than trying to duplicate adobe's black point compensation, I think our time would be better spent exploiting argyll's device link profiles and image specific gamut mapping capabilities. more info on argyll at http://www.argyllcms.com Jay Cox [EMAIL PROTECTED] _______________________________________________ Gimp-developer mailing list [email protected] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
