Haskell library to load & save pictures

Build Status

Juicy.Pixels

This library provides saving & loading of different picture formats for the Haskell language. The aim of the library is to be as lightweight as possible, you ask it to load an image, and it'll dump you a big Vector full of juicy pixels. Or squared pixels, or whatever, as long as they're unboxed.

Documentation

The library documentation can be accessed on Hackage
