Re: White and Black Points



I *thought* I knew what white point adjustment meant but now i'm lost...

Preview.app has a white point adjust feature where the results are
vastly different from Core Image Fun House (and my own code which uses
CIWhitePointAdjust).

How can I achieve the white point results of Preview.app, but using
CoreImage?  If they're not the same thing, why are the named the same?

HI,

Im very confused as to what values to use for the white and black
points for creating a Lab color space in Quartz.  I understand what a
white and black point are.  I also searched the mailing lists and the
internet, but I can't find any examples of creating a Lab color
space.  As of such, Im a bit lost.

Any help would be greatly appreciated.
