Color erase not working in GIMP?Jan 2nd, 2012 | By admin | Category: Random Musings
So after wasting oodles and oodles of people’s time assuming this was a bug and not a human fuck up, as it usually is, I’ve learned that you need to have an alpha channel for this to properly work.
The problem was the paint brush’s ‘color erase’ mode wouldnt’ actually erase colors, it just acted as a normal paint brush. After filing a bug report and going back and forth a little bit I was asked if I had an alpha channel turned set for that layer, which of course I didn’t, and that solved the whole thing. So do yourself a favor and make sure you read instructions properly, unlike me: http://docs.gimp.org/2.6/en/gimp-tools-paint.html
