This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

ChalkBoard is a Haskell hosted Domain Specific Language (DSL) for image generation and processing. The basic structure is a Chalk Board, a two-dimensional canvas of values, typically colors. ChalkBoard provides the usual image processing functions (masking, overlaying, function mapping, cropping, warping, rotating) as well as a few more unusual ones. Images can be imported into ChalkBoard, as first-class color chalk boards. ChalkBoard also provides combinators for drawing shapes on directly on boards. The system is based loosely on Pan, but the principal image type, a Board, is abstract.
