That document predates the publication of CGDataProviderCopyData in the API, though, which should provide a reliable way to access pixel data. In this particular case, it looks like drawing to a new bitmap context would be a more direct route, as you said. However, I'm using CGDataProviderCopyData myself, and I'd like to know where it can fail like this; it WFM so far. -- adam _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
