I have a situation where I need to extract images from lots of PDF files and display them on a website. My PDFs have regular images as well as lots of graphs.I used pdf2xml and it pulls out the images in jpeg, ppm, pbm and vec formats. I see the regular images being extracted (for the most part) as jpeg/ppm/pbm, but I don't see the graphs being there - and so I am guessing that pdf2xml is storing them as .vec files.So the question is how to I get my graphs? I used convert that comes with imagemagick to convert .vec to jpeg/png etc  but to no avail.

I've never tried pdf2xml, but browsing through its files on SourceForge, I found vec2svg-2.py, which appears to be a Python script to convert .vec files to .svg.  You should have no difficulty converting SVG to whatever format you need.python vec2svg-2.py -i file.vec -o file.svg
