friday: A functionnal 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.

The library uses FFI calls to the DevIL image library to read images from a wide variety of formats, including BMP, JPG, PNG, GIF, ICO and PSD. Except for I/Os, friday is entirely written in Haskell.

Images can be represented in two representations:

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.
