Krita is an advanced and modular painting application.

Krita is built around two core libraries: pigment and kritaimage.

The pigment library abstracts colorspaces and color transformations. ColorSpaces provide functions to manipulate pixels. The kritcolor library loads colorspace plugins to extend the range of available colorspaces.

The kritaimage library abstracts the storage, creation, inspection and manipulation of pixels stored in a rectangular area. It provides layers, filters, iterators and painters. Filters and paint operations are provided as service plugins loaded through the appropriate trader queries.

There are the following types of plugins

• filters
• generators
• tools
• brush engines
• colorspaces
• import/export filters
• view plugins: plugins that extend krita with dockers, dialogs etcetera
