Is the goal to go from red to blue from left to right? Why not add a single layer with red on the left, alpha = 1, and blue on the right, alpha = 1? I don't see why you need to composite two layers. Drawing a gradient dynamically is probably more efficient than blitting a PNG, and will be resolution independent. --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
