HowTo: Install & Use Resynthesizer for GIMP

Remember this Photoshop CS5 sneak peak showing off it’s latest and greatest feature Content-Aware Fill a couple months ago, well it turns out a reasonably old plug-in for GIMP (GNU Image Manipulation Program) named Resynthesizer seems to work just as great and because it is what it is, it’s free and open-source.

Installing on Ubuntu 9.10/10.04 install:

sudo apt-get install gimp-resynthesizer

or for the Source/Windows/Fedora Core 4 versions see the download section.

Once you have it installed, it’s simple to use really just select something on your image that shouldn’t be there and right click on the selection Filters -> Map -> Resynthesize.. and up should pop an options box, these settings are pretty standard and will get rid of most things given that they aren’t too big.
