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<y)
-According to the regional polygon filling principle can be extended to the domain filled round, a round of special attributes, can be filled under any wishes to the central pixel and the distance is greater than or less than the radius to determine whether the circle or round, realize the procedure is as follows; Midpoint Circle Algorithm border procedures : void CArea_FillData : : MidpointCircle (int xc. yc int, int r, int color) (//painting of the eighth round int x, y, d x = 0 y = r d = 1-r WholeCircle (xc, yc, x, y, color) while (x
