Readme for friday-juicypixels-

[back to package description]


This library facilitates conversion between friday (an all-Haskell image manipulation library) and JuicyPixels (an all-Haskell encoder/decoder library for many image formats). Combining these two libraries is useful for adding basic image manipulation capabilities of many image formats to a Haskell application without requiring any C libraries/headers to be installed.

NOTE: Expect this library's API to break, as it is still very young.

Compared to friday-devil

The friday-devil package provides a storage backend to friday by calling the DevIL library. It is much more mature, and probably a lot faster (though benchmarks have yet to prove this).

This package is not in the spirit of friday-devil which is a more native bridge than conversion . As such, it should probabably be called something different like juicy-friday.


  • Make it into a storage backend that automatically converts all formats and color spaces supported by JuicyPixels to the internal representations supported by friday.
  • Add some benchmarks. Include friday-devil and ImageMagik.
  • Add more specs.


  • Conversion between JP and Friday for cheap using coerce and unsafeCoerce, yay!
  • Basic test suite.
