Libxml2 for pascal

IMPORTANT NOTE: This project has moved to Github: https://github.com/pkozelka/libxml2-pas Pascal units accessing the popular XML API from Daniel Veillard ( http://www.xmlsoft.org ). This should be usable at least from Kylix and Delphi, but hopefully also from other Pascal compilers (like freepascal).

MuPDFLib for Pascal

An effort to bring the latest MuPDFLib version to PASCAL/LAZARUS, based on the work from Dinko Miljak and Blestan Tabakov. MuPDF is a lightweight PDF, XPS and E-Book Viewer. You do not have many options if you want to included PDF support in your Pascal/Lazarus projects. MuPDF is maybe one of the best options, but is stuck on version 1.08 (from 2015), to be used with Lazarus. I managed to bring the supported version up to 1.17.0 (latest MuPDF). Only for Win64. Help is welcome to bring support for MacOS, Linux and Haiku. As I have no previous experience using external libraries and writing headers for them, I can use some help. So if you want the newest version of MuPDFLib support, please give me a hand.

PasJas

This wrapper is bringing Jasper library to Pascal (Delphi). The JasPer Project Home Page: http://www.ece.uvic.ca/~frodo/jasper/ Support included for jp2(+ j2k, jpc), mif, pnm, ras, pgx formats; bmp and jpeg are excluded, usually included in Pascal (Delphi). All formats can be individually selected using specific defines. It supports irregular geometries and YCbCr on read. Imported jasper structures are valid for jasper-1.900.1 . It is currently compilable with Delphi XE5 but with a few changes should be easily adapted to other versions or FreePascal. Included object files are from jasper-1.900.1, precompiled with Borland C++ Compiler 5.5 (free). The jasper library is compiled WITHOUT any modification using the included bat file.
