I have an image where I want all the pixels with a specific color converted to transparent pixels. The operation should not change the color/alpha value of any pixel which don't match the color exactly. How do I do that?
At first I thought I could use Colors->"Color to Alpha" but that don't work because it changes the color of all pixels(It adds an alpha value to all pixels).
Using Gimp 2.6.11 on Linux
1This was almost right for me. I needed to right click the layer and select
Add Alpha Channel
. Then I usedSelect by Color
. Then I deleted the selection. After that theColor to Alpha
tool wasn't necessary. – bafilius – 2016-05-16T15:25:39.803
