Andrew Douglas Pitonyak (Dienstag, 1.

Consider adding a caption similar to src/toolbox/tool-brush.xml, Paint Mode Examples ("Wilber over a blue background layer") to make that there are two layers. > Complaint 2: > > "create a gradient from color to transparency." > > This has not yet been covered in the documentation (up to this > point).

One way (don't know if there are better ways) is 1. duplicate the layer (wilber with transparency), 2. apply Filters -> Alpha to Logo -> Alien Glow (change the Glow color, e.g. to 255,215,0 = gold). 3. remove the black background layer. But I can't believe that's what the author had in mind. Ulf
