Michael,
two things:
1) Check out the Quartz Composer Programming Guide. The section
"Publishing Ports and Binding Them to Controls" takes about QC ports
and how your program can communicate with active compositions
2) Check out the doc for the QCComposition class. One of the
standard protocols for an encapsulated composition is
QCCompositionProtocolImageFilter which will give you information about
which ports an image filter composition is expecting for proper
operation.
3) The QCTV sample code is a good example of how to communicate
between an application and various Quartz Compositions.
regards,
douglas

I'd like to access programmatically the quartz composer image
filters(just like it's done in the Automator script "Apply Quartz
Composition Filter to Image Files). How do I do this? Are they really
just CIFilters of a particular category?
