如何在Visual C++中实现Choen

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

地图中等值线的识别与矢量化，可以实现从栅格地图（目前支持bmp,emf等文件）中获取等值线.GIS工程有用的。-contour map of identification and vectorization, can be achieved from the raster maps (currently supports bmp, catalog, etc.) access contours. GIS projects useful.

Polygon clipping is one of those humble tasks computers do all the time. It s a basic operation in creating graphic output of all kinds. There are several well-known polygon clipping algorithms, each having its strengths and weaknesses. The oldest one (from 1974) is called the Sutherland-Hodgman algorithm. In its basic form, it is relatively simple. It is also very efficient in two important cases, one being when the polygon is completely inside the boundaries, and the other when it s completely outside.
