Extracting images from a PDF file

[Doug Farrell]

Hi all,

Does anyone know how to extract images from a PDF file? What I'm looking
to do is use pdflib_py to open large PDF files on our Linux servers,
then use PIL to verify image data. I want to do this in order
to find corrupt images in the PDF files. If anyone could help
me out, or point me in the right direction, it would be most
appreciated!

Also, does anyone know of a way to validate a PDF file?

Thanks in advance,
Doug

If you are ok shelling out to a binary:

pdfimages - Portable Document Format (PDF) image extractor (version
3.00)
http://packages.ubuntu.com/gutsy/text/xpdf-utils

I am trying to convert the pdf to a png, but without having to run external
commands. so I will understand if you arn't happy with pdfimages.

Carl,

Thanks for the feedback, and I don't mind shelling out to an external
command if it gets the job done. Thanks for the link to xpdf-utils,
I'm going to look into it this morning.

Hi,

Our linux servers run CentOS (4.X) I believe, and the repositories for
this version doesn't have xpdf-utils available. I'm going to look into
editing the sources.list file in order to get yum to install the
necessary dependencies for me as xpdf-utils looks very useful!
