I would like to make a (semi-)transparent brush in GIMP.

Starting from an image of marble with white background and veins in shades of grey, using various layers I selected the white to alpha and then changed the Hue, so now I have nice red veins on a transparent layer. I would like to turn this transparent layer with the red veins into a brush.

However, whatever I try, the brush has a white background colour (even when I delete all other layers).

I just want the veins on the brush, no background colour. Is there any way to retain the transparency while creating the brush?

Thanks! Gladys.

  • What did you do to create a brush from your image? Commented Dec 20, 2015 at 19:01

If you just do Edit > Copy (or Ctrl-C) the layer and then Edit > Paste as > New Brush, the layer should be saved with transparency and paint that way.

(Perhaps a little confusingly, the brushes are always displayed with a white background in the Brushes dialogue, but for me a brush saved with transparency does actually paint as expected whichever paint tool I use.)

If that does not work for you, what version of GIMP are you using ?

  • Does not appear to work. The transparent pixels become white pixels in the brushing result even though the pixels are transparent in the brush file itself. Commented Nov 11, 2023 at 9:13
