Thank you so much for the responses guys. This is the reason I was confused:
NSDeviceWhiteColorSpace Device-dependent color space with white *and alpha components* (pure white is 1.0) Available in Mac OS X v10.0 and later. I thought that NSDeviceWhiteColorSpace had BOTH a white and alpha channel. I hate it when the docs are incorrect. And I copied that method call from an Apple sample... I'll remove the extraneous casts. :) Thanks again, Simon On Sun, May 30, 2010 at 10:08 PM, Seth Willits <sli...@araelium.com> wrote: > On May 29, 2010, at 7:09 AM, Simon Raisin wrote: > > > I would like to create an 8-bit grayscale image but I cannot find a color > > space that uses only 1 8-bit value per pixel.
