[Gimp-user] Fill transparent?
Hi All, I'm really sorry this is probably a dumb/rtfm type question but I guess I don't know enough to know what to look for. I simply want to make a selection transparent. I can make the selection OK, but when I click the little red eraser thingy (for which the tooltip says "Erase to background or transparency" I can't make it make the selection transparent no matter what I try. Can anyone tell me what I should be doing please? Many thanks, Simon "You can tell whether a man is clever by his answers. You can tell whether a man is wise by his questions."

Oh, wow, that's easy. I guess I really just didn't know where to begin. Many thanks :) Simon "You can tell whether a man is clever by his answers.

Invoke the Layers dialog. (Dialogs -> Layers). 2. Right click the layer that you wish to make transparent and select "Add Layer Mast". Select "Layer's alpha channel" in the dialog that pops up. 3. Select the layer mask (that's the square to the right in the layer). 4. Select the "Fill with a colour" tool from the GIMP's toolbox. 5. Select a black colour. 6. Make sure that you are filling with the foreground colour, and filling the entire selection. 7. Click the mouse inside the selection in the image window. 8. Right click on the layer in the layers dialog and select "Apply Layer Mask". --- Hope it helps.

"Add transparency" or something like that. gimp does not fill with transparency. it erases, clears, cuts or uses masks to make transparency. gimp handles selections its own way. forget everything you know about them. carol ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] gradient lighten
Hi all, Quick newbie question. I have a photo that is full bright on one side, the left; and subdued light on the right. It seems to be an excellent job for gradient and layers but I'm not sure how to go about getting started. I checked in tutorials and couldn't find anything on this specifically. tia, Bill W. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

(or maybe a duplicate of the photograph instead) carol ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
