As I do not think my former message reached gimp-users, I will try there (it also seems more fit, and I am subscribed): Is there any way to directly edit the alpha layer of a layer. Layer masks do only reduce the alpha, never increase it; and sometimes I would like to somehow delete any opacity information in a layer, without having to repaint all. So maybe there is a solution, but I didn't find this (since editing a mask is not the answer)... Sincerly, -- JCD
