是一个开源的、高效的2D图形库，它的网站：http://www.antigrain.com/
AGG的功能与GDI+的功能非常类似，但提供了比GDI+更灵活的编程接口，其产生的图形的质量也非常高，而且它是跨平台的，其宣传可以在非常多的操作系统上运行。
功能：
Rendering of arbitrary polygons with Anti-Aliasing and Subpixel Accuracy. Gradients and Gouraud Shading. Fast filtered image affine transformations, including many interpolation filters (bilinear, bicubic, spline16, spline36, sinc, Blackman). Strokes with different types of line joins and line caps. Dashed line generator. Markers, such as arrowheads/arrowtails. Fast vectorial polygon clipping to a rectangle. Low-level clipping to multiple rectangular regions. Alpha-Masking. A new, fast Anti-Alias line algorithm. Using arbitrary images as line patterns. Rendering in separate color channels. Perspective and bilinear transformations of vector and image data. Boolean polygon operations (and, or, xor, sub) based on Alan Murta's
