In general, the answer must be that a copy ought to be expected. That’s because a data provider is not required to have a data buffer, so there’s not necessarily any underlying data to access directly. (The actual data could be streamed, or generated procedurally.) If you can limit the kinds of image sources, you might get a more specific answer. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
