I have an image where the background is white and there are various important components that are also white. I want to just change the background to alpha, but "Colors to Alpha" - by default - changes all the white to alpha.
Please help and thank you!
Answer
If the image is in a single layer, select the areas you want to go transparent with the "Magic Wand" (Fuzzy Select) tool instead.
Them just Edit->Cut to get rid of the selected parts. (Make sure your background layer has an alpha channel Layer->Transparency->Add Alpha Channel).
If your background is in a different layer, then just delete/hide that layer.
