用MFC做的绘图程序，里面的画线算法，画圆算法，梁友栋算法，扫描线种子填充算法等等都是严格按照书本的编写，适合学计算机图形学的初学者参考-Using MFC to do the drawing program, draw lines inside algorithm, drawcircle algorithm, You-Xin Liang Dong algorithms, scan line seed fill algorithm and so on are all in strict acco

编写一个程序，在屏幕上出现一个圆心沿正弦曲线轨迹移动的实心圆，而且，每隔四分之一周期，圆的填充色和圆的周边颜色都发生变化，同时，圆的半径在四分之一周期之内由正弦曲线幅值的0.2倍至0.6倍线性增长。 -Write a program that appears on the screen along a sinusoidal trajectory of the center moving solid round, and every quarter cycle, a circle filled
