基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)

集中介绍了HDC,CDC,CClientDC,CPaintDC,CWindowDC的使用方法和区别，绘图显示效果，区分窗口客户区。(Focus on the HDC, CDC, CClientDC, CPaintDC, CWindowDC to use and distinction, graphics effects, to distinguish the window client area.)

图形学画图,直线,圆,多边形,曲线,随手画,文本,裁剪(Graphics drawing straight lines, circles, polygons, curves, hand painting, text, cutting)

本代码是进行齿轮参数设计和参数校核，参数化绘制二维工程图的源代码(gear parameters for the design and verification parameters, parametric mapping of two-dimensional engineering drawings source code)

本程序可以在MFC中打开并显示一张图片，代码比较简单基础(Open and display a picture in MFC)
