mtPaint 3.21 is a Image Editing Software product from mtpaint.sourceforge.net, get 4 Stars SoftSea Rating, mtPaint is a simple painting software which I developed from scratch so I could easily create pixel art and manipulate digital photos.
It uses the GTK+ toolkit (version 1 or 2) and runs on PC's via the GNU/Linux or Windows operating systems. Because of its simplicity it can also run on older PC hardware (e.g. a 200MHz CPU and 32MB of RAM).
By default it is in the English language, but there are also translations available for other languages such as Spanish, Czech, French, Portuguese and Brazilian Portuguese.

Version 3.21 has new Galician and Russian translations, updated Spanish translation, and several small improvements and bugfixes.
