1) Why can't you use an overlay window? Just convert to window coordinates and clip appropriately when objects are out of view. 2) If you want to go the image route, I'd use a Quartz mask. Saves you from having to render the blur at runtime. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
