Anyone know where I should be looking? how about [rep isKindOfClass:[NSBitmapImageRep class]]? that's how to check prior to casting that a given cast is allowable. But as long as the rep supports being drawn, you can always create your own NSBitmapImageRep and draw any other kind of rep into it, then extract the data of the one you created as PNG. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
