[poppler] PDF editing operations

[Shawn Rutledge]

Is there any plan to support some basic editing operations, some of
which pdftk can do, like rearranging page order, renumbering pages,
editing metadata or OCR text inside the PDF?  I saw in the Qt4 binding
documentation that it's possible to write an open PDF document as a
new PDF, and there is a flag to preserve changes or not, but what are
the changes that it supports?

I'm scanning a bunch of old magazines that take up too much space in
boxes (Radio-Electronics, Popular Science etc.) and was thinking of
writing a program to recognize the name and date of each scan (look
for the known magazine titles, month names etc. in the margins), and
auto-number the pages (look for page numbers in known likely
locations).  I confirmed that GOCR is good enough to extract page
numbers from page images.  I could probably just use pdftk to do the
renumbering, but also thought of making a better integrated tool
rather than just a scripting solution.

I actually bought Acrobat to do OCR on the scans, but it does not have
such features.
