Paint on your PC using a large brush collection or your own custom brushes, with MyPaint
MyPaint is a fast and easy open-source graphics application for digital painters. It lets you focus on the art instead of the program. You work on your canvas with minimum distractions, bringing up the interface only when you need it.
Features: It supports pressure sensitive graphics tablets such as the Surface * extensive brush creation and configuration options * unlimited canvas (you never have to resize) * basic layer support.
MyPaint comes with a large brush collection including charcoal and ink to emulate real media, but the highly configurable brush engine allows you to experiment with your own brushes and with not-quite-natural painting;
MyPaint is not an image retouch program, effects application, etc.; it is meant to be used by painters only, and it manages indeed to convey a sense of real painting.
