I've been exporting PPT 2007 slides as pngs for use in tv broadcast. What i've been doing is printing them to a PDF file, then opening in photoshop and resizing etc. for the pngs I need.

Problem is, during the pdf process, PNGs, Excel charts and semi-transparent fills all come out screwy in the pdf. (I didn't create the slides), but to bypass Acrobat's sucky handling of Excel, etc, I end up spending hours tweaking out/replacing the pngs, excel charts etc to show up properly on the pdf, and ultimately, the png file.

Tried exporting directly from PPT, but need higher quality.
Anyone know of any 3rd party programs that will CLEANLY export a ppt slide as a png file? Would save a hell of a lot of time! Thx!
