Haskell Image Processing (HIP) Library
Haskell Image Processing (HIP) Library provides an easy to use interface with a whole variaty of image manipulation capabilities. Processing can be done sequentially as well as in parallel, with an inherited fusion capabily, all through<https://hackage.haskell.org/package/repa repa>and<https://hackage.haskell.org/package/vector vector>packages. It is highly extendable, with an ability to add various color spaces or provide implementations for underlying array like custom data structures. It is capable of reading and writing a number of popular image formats by using<https://hackage.haskell.org/package/JuicyPixels JuciyPixels>and<https://hackage.haskell.org/package/netpbm netpbm>packages. Being a pure Haskell library it does not require any external programs, although it can display images using a program of your choice.
