Our pdf2picture tool converts PDF files to the native Windows vector
format WMF, which you can import and edit in Powerpoint. Graphics,
images and text strings are all supported and reproduced as such in
WYSIWYG layout.
See
http://www.pdf2picture.com for more information and a free trial. You can
also send me a sample PDF file via email for a quick test.
The tool ($59) is listed on the Microsoft Office Marketplace, and is
referenced in the online Help for Publisher, Visio, PowerPoint etc.
