extracting vector graphics from a PDF

[Steve Kleene <skdeb@syrano.acb.uc.edu>]

Can anyone tell me how to extract a vector graphics image from a PDF?

The PDF was created with LaTeX, so I'm pretty sure the image was incorporated
as vector graphics (PS or EPS).  I am aware of pdfimages from the
poppler-utils package, but it only handles raster graphics.

I'd prefer to do this from Lenny but also tried XP.  Under XP, I have Acrobat
9.3.1 and Illustrator 9.0.  Illustrator couldn't open the PDF, and I couldn't
find a way to export the image from Acrobat.

Thanks.
