The DDImage library is the shared library section of Nuke. It contains all the interfaces needed by Nuke plugins. Originally DDImage was concerned with image processing (thus its name) but it has expanded to cover some 3D and general math operations needed by Nuke plugins, and contains stub code (replaced by Nuke with pointers to its own code) for the user interface operations available to a plugin.

This document contains all information needed to write plugins for the Nuke compositor. You will find links to fully documented sample code at the bottom of this page.
