im4clj is incomplete and is not currently under active development.
I personally, reccomend using a generic shell scripting tool like https://github.com/Raynes/conch instead.

ImageMagick/GraphicsMagick commandline wrapper for Clojure.
See the im4clj wiki and the im4clj API docs for more detailed information.
