I think Mac OS X uses ColorSync pervasively for this kind of stuff,

If it is using ColorSync, it's probably doing everything via ICC
profiles, so I doubt you'll find out it's using the "one minus" method
or anything like that. There may be "fast paths," though, for
particular color spaces.
hi-
yup, I'm using a few modified one minus method from adobe, etc., but it
needs some work. About 5 years ago someone on this list gave some
different ones, but I don't remember them. I don't see any functions to
get transformation profiles from a ColorSync lib either.
thanks!-
