after that, i suggest working with the eraser directly on the image to see if that can do what you would like. you can adjust the transparency in the tool options. > I found out that I can do "Layer -> Add Mask", then > paint (eg using gradients, with "multiply" ) and then > do "Layer -> Apply Mask" which gives me the desired > /visual/ result, but I would like to apply the mask > to the /alpha/ channel and not to the /r/g/b/ channels. > > How would I do this? > where the layer mask is white, there is no transparency. where it is black it is transparent. gray produces semi transparency. try by adding a white layer mask, select an area on it and fill that with black. paint a black to white gradient on the mask and it will be transparent to opague according to how you painted the gradient. carol _______________________________________________ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
