convert the pdf to text and read it with moonshell.I have not found any free PDF to image converters
Stole this off Ask Metafilter:
QUOTEThis is something where the open source Ghostscript really shines, especially for converting documents with lots of pages, where using Acrobat's snapshot tool can get very tedious.
Get the latest versions of Ghostscript and GSView from this page and install. Install Ghostscript first, then GSView. Open the .PDF in GSView, go to File->Convert and pick 'jpeg' from the list on the left. You can then select the resolution you want to export at (72 is probably what you want). Pick OK. Navigate to where you want the JPGs to go, and type in for the file name: shadowrun%03d.jpg. Pick Save and it'll start chewing through, creating shadowrun001.jpg, shadowrun002.jpg, shadowrun003.jpg, etc., for every page in the PDF.
