Splitting PPT animation using C#

Question

This is the last resort of my problem. I'm trying to split animated PPT slides into several flattened slides.

1. http://neilmitchell.blogspot.com/2007/11/powerpoint-pdf-part-2.html I have translated the code into C#, and it works fine, except it doesn't handle appearing/disappearing bullets.

2. http://www.dia.uniroma3.it/~rimondin/downloads/PPspliT/1.1/PPspliT-source.txt This works better when being run as an add-in or a macro. The problem is that it's hard (read: too long) to translate it into C#.

My questions:

1. Is it possible to detect/split the bullets by just using the code from link #1? This is the preferable method since the code is already simple.

2. If that's not possible, can I create/run the macro from C# in the runtime? The macro would have not been installed/existed in the PPT file. I imagine this will be impossible since macro feature would have to be enabled in the PowerPoint program before it could be run.

3. Other solutions are welcomed!

Thanks.
