.Mage is a small and fast graphics editor slanted towards quite and easy pixel editing, ala DPaint from the DOS/Amiga days. Instead of being a bloated behemoth with a zillion plugins it starts in under a second and it does a lot of the mundane jobs of image editing quickly and without fuss. The right tool for simple jobs.
Source code is available under the LGPL. If you don't see links in the download section I can provide then on request. I'm usually hacking on code rather than keeping every last i dotted and t crossed. If you don't see a feature you want your welcome to add it to the code and send me a diff.
While i.Mage is not deprecated I don't spend a lot of time on it these days. Requests for features or bug fixes may take some time to get some attention.
