I have searched for PDF reader library that is licenced under LGPL or the like but could not find. I found only GPLs. Now I need a help to write my own library to read the PDF file and display it in my app. I have downloaded PDF Specs 1.7 from Adobe and I'm trying to search out a beginner tutorial but I'm yet to find one.
Is there a beginner tutorial for writing my own reader library (only reader)?
Thanks
Since you can't find a PDF read tutorial, why not try learning from a writer. If you want to integrate with wxWidgets, you may want to analyze the source of wxPdfDocument at http://wxcode.sourceforge.net/components/wxpdfdoc/

I want to look at the source code of a PDF printer to see how they do the printer driver part, but so far I've only found PDF Creator which is written in VB. There are plenty of freeware PDF printers but they're not open source, and I need to look at the source code.
Here the project EmfPrinter written in C++.
I use OpenOffice to convert Word documents to PDF.
I believe the source code is available.
If you really only want the "printer driver" part then this may not be what you're looking for. But if you're interested in the PDF generation then it may very well be.

I need to develop a video generator that takes in a set of images, music files and outputs mp4 videos. The platform is linux. Was wondering if there are any existing libraries that can do this job ?
Thanks
I believe Processing can do what you want.
you can use ImageMagick for video part. It has both good graphics/video library and corresponding console application. For sound embedding use gstreamer.

Does any know of any C/C++ open source for XPS [XML Print Specification].
I found http://www.ndesk.org/Xps, but it is c# ...
Any help will be highly appreciated.
I know of two open source implementations of XPS parsing and rendering: there is GhostXPS for use with Ghostscript, and MuXPS. MuXPS is a fork of GhostXPS which is based on the MuPDF graphics library instead. MuXPS is still very new, but you can find the source in the MuPDF git repository.
Mighty Wikipedia says that KDE Okular supports OpenXPS.
Artifex has GhostXPS which can read XPS packages

I am looking for an open source C/C++ image/video thumbnail generation libraries.
(other than ffmpeg or DevIL)
Will Image Magick work? It is quite a capable library with C++ (and C) bindings. It does support grabbing still frames from some video formats, see here. It's a command-line example, but should work from the API as well.
Try ffmpegthumbnailer:
This thumbnailer was designed to be as fast and lightweight as possible. The only dependencies are ffmpeg, libpng and libjpeg.

Can you recommend an open source library (C or C++) to convert MS Office files into a set of images?
I am evaluating ImageMagick and while it does support PDF files, it does not work with MS Office files.
This library is quite popular and used by abiword (gnome) and kword (kde): wvWare
Hm I've seen that OpenOffice does a good job on "translating" Word to whatever, so how about installing OpenOffice and maybe using it's UNO model from C++ to solve that problem?
