You have to mess around with the mask getting its pixels just the right value to make the pixel's alpha value right, which is probably harder than using the cut/paste/merge method I mentioned previously. What I really want to be able to do is enter a number and set the selected pixels' alpha transparency to that number. -- Best regards, Jeremy Morton (Jez) _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
