Anti-Grain Geometry (AGG) is an Open Source, free of charge graphic
library, written in industrially standard C++. The terms and conditions
of use AGG are described on The License page. AGG doesn't depend on any
graphic API or technology. Basically, you can think of AGG as of a
rendering engine that produces pixel images in memory from some vectorial
data. But of course, AGG can do much more than that. The ideas and the
philosophy of AGG are:
* Anti-Aliasing    * Subpixel Accuracy    * The highest possible quality
* High performance    * Platform independence and compatibility
* Flexibility and extensibility    * Lightweight design
* Reliability and stability (including numerical stability)
