The repa-image library adds support for reading and writing images in many formats based on the DevIL open source image library. Image data is represented in Haskell as typed, multi-dimensional repa arrays.
Developer's Image Library (DevIL) is a library to develop applications with very powerful image loading capabilities, yet with a relatively simple interface. DevIL can load, save, convert, manipulate, filter and display a wide variety of image formats, including:
BMP, ICO, JPG, PNG, PNM, TGA, TIF, GIF, EXIF and many more.
