Any way?
You could try creating an overlay window and setting its color space to your target color space using -setColorSpace. Put an NSImageView in that window, and hand it a version of your image that you've retagged into the destination colorspace using -bitmapImageRepByRetaggingWithColorSpace:. N.B.: This might not actually be any faster. I've never tried it. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
