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 repa and 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 JuciyPixels and 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.
