Perhaps you could use separate images and convert them to monochrome, saving them as 1 bpp bitmaps (aka masks). Memory should not then be an issue.

You can either create a bitmap image for each touchable area, or a single image with a different color for each target, then test the color at the target point to determine membership. My only concern with using this approach on iPhone might be the memory usage of that image. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
