Ursprunglig bild

”Color to Alpha” applied on blue areas

The Color to Alpha command makes transparent all pixels of the active layer that have a selected color. An Alpha channel is created. It will attempt to preserve anti-aliasing information by using a partially intelligent routine that replaces weak color information with weak alpha information. In this way, areas that contain an element of the selected color will maintain a blended appearance with their surrounding pixels.
