Integrating the MyPaint Brush Engine with Krita
Summary
MyPaint developers have separated out their brush engine in the form of a library, libmypaint. Artists like MyPaint brushes a lot and it would be good to integrate the same as a new brush engine within Krita brush engine subsystem.
The project has two objectives:
- To integrate the MyPaint brush engine in the form of a new brush engine in Krita, enable it to load the MyPaint brushes from system and use them for painting in Krita.
- To implement a preset editor to edit existing brushes and also create new ones.
By the end of the project, Krita will have a new brush engine that can be used for painting with MyPaint brushes and also create and edit them.
Project Goals
- Implement a new brush engine in Krita that can be used for painting.
- Enable Krita to load installed MyPaint brushes from the system.
- Implement a preset editor for editing and creating MyPaint brushes.
