根据多边形区域的填充原理可以推广到圆域的填充，由于圆的特殊属性，即可根据任何欲填充的像素点与圆心的距离是否大于或小于半径来判断是否在圆内或圆外，具体实现程序如下； 利用中点画圆算法实现边界程序： void CArea_FillData::MidpointCircle(int xc, int yc, int r, int color) {//画八分之一的圆 int x,y,d x=0 y=r d=1-r WholeCircle(xc,yc,x,y,color) while(x

二维图形渲染引擎，可以同时对二维的BITMAP和矢量进行操作（通过一序列的API函数，基于AGG）-Graphin is a 2D graphics rendering library with human readable yet simple external interface (API). It is based on AGG- high fidelity 2D graphics engine and uses libpng/zlib, jpeglib and libtiff(?). External (plain C) API is as close as possible to Graphics and/or to Canvas.
