Writing PlugIns and image filters for Acorn
Download sample code and header files: http://flyingmeat.com/download/latest/SampleAcornPlugins.zip
Acorn provides a plugin interface for developers, in both Objective-C and Python (using the PyObjC bridge). Acorn also uses any Core Image Units that are installed on the computer, which is also an option if you want to provide filtering services to Acorn.
