Hi,

I thought subscribers to this list might be interested in a small
program that used poppler.

DiffPDF is a program for comparing two PDF files.

Two comparison modes are supported: Text and Appearance. Text mode is
quite fast. Appearance mode is useful when checking for changes to
figures or for items that have moved (e.g. reformatted paragraphs).
Comparisons can be between entire documents or between particular pages
or page ranges (for example, to account for pages added to one PDF but
not to the other).

This release introduces a much improved text comparison algorithm (based
on the Python difflib's SequenceMatcher) that is far more intelligent
than the old algorithm.

The program is distributed as C++ source; it requires a C++ compiler
e.g., gcc, and depends on the Qt 4 libraries (e.g. Qt 4.5 or later) and
the Poppler library. It is licensed under GPL v 2 (to match Poppler's
license).

DiffPDF is available from: http://www.qtrac.eu/diffpdf.html

Perhaps someone who has access might be willing to add this program to
the http://freedesktop.org/wiki/Software/poppler page's "Programs using
poppler" table?
