2.7.3. Layer Modes

Layers can be merged using other methods besides their Alpha. These are available in the "Mode" combo-box of the layers dailog.

Demo

  1. Generate an image with <Toolbox> -> Xtns -> Script-Fu -> Patterns -> "3D Truchet" .
  2. Duplicate the layer using <Layers> -> Duplicate Layer .
  3. Render a nice gradient on the lower layer.
  4. Change the mode of the upper layer to Screen.
  5. Switch the mode to Addition and then to Subtract and to to other modes.

The operations that are used to merge the various layers are described the in the Gimp User's Manual.
