PDF library?

[Paul Rubin]

I have a big PDF file that I'd like to crunch, i.e. I want to select a
certain rectangular area from each page and make a new PDF combining
the selected areas from adjacent pages. I guess that means I need a
Python wrapper for GhostScript, or something similar. Anyone know if
that exists? Thanks.

Reportlab generates reports in pdf format, but I want to do the
opposite, namely read in pdf files that have already been generated by
a different program, and crunch on them. Any more ideas? Thanks.

The commercial version (reportlab.com) mentions a tool named
PageCatcher, that seems to be able to extract pages and page descriptions
out of .pdf documents. There is not that many information on the web-page.

If you read comp.text.tex you will find various solutions for composing
and a few for extracting data/content from .pdf documents. Afaik there
is at the moment (read as: i'm working on it) no free-self-contained-
python solution. But as python is very interface-friendly you can use
general tools like gs easily.

For your problem i would suggest to use gs als a .pdf to .ps filter
in the first place, work on the .ps and distill back with gs.

Wishing a happy day

Reportlab does that as well, but you either have to pay them money or live
with a Reportlab watermark added to each page you process. So, if you are
doing this for fun it may not be a useful answer, but if its commercial you
can investigate it for free and pay later to remove the watermark.
