An image library that offers support for image reading and writing of Repa arrays using in-place FFI calls.
The repa-image library adds support for reading and writing images in many formats. Image data is represented in Haskell as typed, multi-dimensional repa arrays.
Developer's Image Library 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.
