Removing background

Someone did a really nice tutorial on this issue recently and posted the url to this list. Of course I don't know where a searchable archive is so that does not help much does it?

The tutorial is at
http://www.gimp.org/~sjburges/color_to_alpha/color2alpha.html

Do note that my tutorial works best for non-photographic images, but you can use it to get close with photographic ones and touch up what you need to afterwards.

Its not in general an easy problem. There's not really a great tool for it yet in Gimp; this filter goes totally agressive and leaves no hint of the color to be removed.

Happy GIMPing,

Seth Burgess sjburges@gimp.org

i like this plug-in best on a selection. it removes the background and can anti-alias the edges nicely after you tweak the selection a bit.

Hmmm. I may try select by color and grow the selection by a couple of pixels and then color to alpha at least it won't freak out the rest of the image. Thanks for the tip Carol.
