Synopsis

MyPaint has made available their brush engine in the form of libmypaint library for integration in other painting applications.
This aims to integrate MyPaint brush engine in Krita so that artists would be able to use MyPaint brushes from within Krita itself.

Goals

• The first objective is to integrate MyPaint brush engine in Krita so as to facilitate using and creating of MyPaint brushes.
• The second objective is to expose the MyPaint brush options in Krita's brush editor and allow modification of MyPaint brushes.
