I have a very limited understanding of how rich media content is used in PDF docs, but have been experimenting with add graphical UI contols (using flash to created buttons) and adding them to PDF's ... but I have had a thought about using Catalyst to do this ... mostly to illustrate a point ...
I am wondering if this is possible and how would one go about doing this ...
If you have Adobe Acrobat Pro, you can embed SWF content in your PDF via the Movie Tool (in the Advanced Editing toolbar). More details are available in this tutorial.
To export a SWF file from Flash Catalyst, choose "File > Publish to SWF."
Hope that helps!
