CGImageGetDataProvider and CGImageProviderCopyData should do what you want. -- adam ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

That second call should of course be CGDataProviderCopyData... sorry. -- adam ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Bitmap data from CGImageRef
Thanks Adam.. For some reason I cannot seem to find CGDataProviderCopyData in the Apple docs. I can search for it at the ADC, and it returns the page for CGDataProvider as the first hit, but once you go to that page, there is absolutely no reference to CGDataProviderCopyData. Strange.

There was another thread on quartz-dev that noted that. Someone at Apple said they would look into it. FWIW.

Re: Bitmap data from CGImageRef
Surprisingly, if you go to Xcode Documentation you can find the method that Adam first mentioned, but it is not on the ADC website. Thanks Scott.
