I have a gif file with a round logo on top of transparent background. The border around the round item needs to be antialiased.
I have tried selecting with the fuzzy wand as well as with border: 2px, but either case I'm not able to choose Color to Alpha nor Blur Gaussian Blur as suggested in many tutorials.
I have also tried changing the format of the file to xcf
Any ideas? Gimp 2.6.12 on Ubuntu 12.04
