Thanks for the pointer. :-) If the device colorspaces were just generic ones, my test program would work.
I heard back on my bug, though. Indeed, the device spaces are no longer device dependent. The device RGB space at least at the moment coincides with the colorspace of the main display. (The urging in the docs is that you replace usage with a generic space, not that device and generic spaces are the same.) Anywho, just to close up, yes, you're seeing color transformation. Fill with a color that's already in the destination colorspace to avoid it. -Ken On Fri, May 30, 2008 at 5:15 PM, Michael Vannorsdel <[EMAIL PROTECTED]> wrote: > This is from the CGColorSpaceCreateDeviceRGB docs: > > In Mac OS X v10.4 and later, this color space is no longer device-dependent > and is replaced by the generic counterpart—kCGColorSpaceGenericRGB—described > in "Color Space Names".
