vc++上mfc绘制图形，包括直线，像素点，圆，矩形等(MFC draw graphics on vc++, including straight lines, pixels, circles, rectangles and so on)

采用VC++编写的画线程序，有3种实现算法，包括DDA，Midpoint，Breseham，计算机图形学。(Drawing a line using C++ written procedures, there are three kinds of realization of algorithms, including the DDA, Midpoint, Breseham, computer graphics.)

MFC图形学 多边形边缘填充算法 直接用VC打开编译即可运行(MFC graphics polygon edge fill algorithm can be run directly by VC.)
