I have a stack of layers where some of them need to clip outside the path of one of them and all the layers are naturally transparent so I can't fill the clip one with a background and stuff it on top hiding those below. Each layer has one close path on it at this point so using paths is ideal if I can figure it out. Someone suggested a clip mask, that might work if I can't get the paths to go; I feel for some reason that a clip mask would be less efficient and this should be totally do-able with paths and paths are what I naturally have here. Time to start TestClippy and work this out, thanks for the suggestions. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
