GNU libxmi 1.2

GNU libxmi is a C/C++ function library for rasterizing 2-D vector graphics. GNU libxmi can draw 2-D graphical primitives, including wide polygonal lines and circular and elliptical arcs, into a user-supplied matrix of pixels. Sophisticated line styles, such as multicolored dashing patterns, can be specified. There is also support for filling and texturing polygons.

The current version of the libxmi package is version 1.2, released in June 2000. It can be installed on GNU/Linux, FreeBSD, and Unix systems. Since libxmi is written in ANSI C, it should be easy to compile and install on almost any system with a C compiler.

What is libxmi good for?

It can be used as a drop-in rendering module in any application that needs to scan-convert 2-D vector graphics. It is highly customizable. For example, the `pixel datatype can be redefined at compile time. The algorithm used for compositing pixels can be redefined too. By default, libxmi uses the Painters Algorithm (a new pixel value replaces an old one). But it would be trivial to install it so that it uses alpha compositing instead. The package, and its header file xmi.h, include full documentation.
