friday: A functional image processing library for Haskell.

[ graphics, lgpl, library ] [ Propose Tags ]

Friday provides functions to manipulate images in a functional way. The library is designed to be fast, generic and type-safe.

Images can be represented in two representations:

  • the Manifest representation stores images in Haskell Vectors ;

  • the Delayed representation uses functions to produce images pixels. These images can be combined to produce complex transformations. By some inlining, Haskell compilers are able to produce fast algorithms by removing intermediate structures.

The library currently support four color spaces: RGB, RGBA, HSV and gray-scale images.

Please read our README to get a detailed usage and some examples.


Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.
