Today, I heard from Mark Summerfield

Hi Steven,

I’ve just released DiffPDF 1.2.0.

There are small improvements in the user interface plus a tiny bug fix
of one setting that wasn’t saved/restored correctly.

I am hoping that this will be the last release for quite a while!

I’d be very grateful if you’d create a statically built Windows version:
your build for 1.1.5 is proving very popular!

Thanks:-)

So I compiled and released it in the first time, feel free to download it here

P.S. Change logs

Recently I tried to compile PoDoFo on Windows using Mingw, so i did some researches, and found 6 projects that use PoDoFo as PDF editing library.

• PoDoFoBrowser

PoDoFoBrowser is developed with Qt4 by the same author of PoDoFo, a gui for editing the object structur of PDF files directly.

• Scribus

Scribus is an Open Source program that brings award-winning professional page layout to Linux/UNIX, Mac OS X, OS/2 Warp 4/eComStation and Windows desktops with a combination of “press-ready” output and new approaches to page layout.
Underneath the modern and user friendly interface, Scribus supports professional publishing features, such as CMYK color, separations, Spot Colors, ICC color management and versatile PDF creation.

• Calibre-ebook

calibre is a free and open source e-book library management application developed by users of e-books for users of e-books

• Comment

Comment is a PDF annotator (tailored to the author’s needs as a mathematician who wants to comment articles and save the comments for later reference with the pdf files).

• OkularAnnotMerge

OkularAnnotMerge is a quick and dirty hack to merge okularannotations (saved in a xml separate from the annotated file) into the pdf.

P.S.

PoDoFo is a library to work with the PDF file format. The name comes from the first letter of PDF (Portable Document Format). A few tools to work with PDF files are already included in the PoDoFo package.
The PoDoFo library is a free, portable C++ library which includes classes to parse PDF files and modify their contents into memory. The changes can be written back to disk easily. The parser can also be used to extract information from a PDF file (for example the parser could be used in a PDF viewer). Besides parsing PoDoFo includes also very simple classes to create your own PDF files. All classes are documented so it is easy to start writing your own application using PoDoFo.
PoDoFo is written in C++ and the code was sucessfully compiled under Unix, Mac OS X and Windows.

DiffPDF is developed by Mark Summerfield, I just compiled it to windows 32 version.
DiffPDF depends on poppler, poppler-qt, Qt4 library.

DiffPDF can compare two PDF files. It offers two comparison modes: Text and Appearance.
By default the comparison is of the text on each pair of pages, but comparing the appearance of pages is also supported (for example, if a diagram is changed or if a paragraph is reformatted). It is also possible to compare particular pages or page ranges. For example, if there are two versions of a PDF file, one with pages 1-12 and the other with pages 1-13 because of an extra page having been added as page 4, they can be compared by specifying two page ranges, 1-12 for the first and 1-3, 5-13 for the second. This will make DiffPDF compare pages in the pairs (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).

It is open source(of course free software), want to try it on your windows XP/Windows 7, please download here.
