Source Code

If you know Python, you can easily write actions with the documentation of Python Image Library (PIL), which is also the base for the documentation of a lot of the actions listed above. You can browse the source code of the actions in folder /phatch/actions on launchpad. Most actions have the PIL function first, followed by the action which provides it.
