Changing the Color Space of NSImage

Is there a way I can change the color space of an NSimage or NSBitmapImageRep/CGimage or the like. I am open to any way. Preferably the way photoshop does it.

Solution 
  • CGImageRef CGImageCreateCopyWithColorSpace (
   CGImageRef image,
   CGColorSpaceRef colorspace
);

    To get a CGColorSpaceRef, you can do things like

    CGColorSpaceRef CGColorSpaceCreateDeviceRGB();

    OR see this page for how to create other color spaces.
