A simple graphics class for 2D drawing

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.)

读取文本中的数据，然后应用Qpainter进行绘图。(Read the data in the text, and then apply the Qpainter to plot.)

一个完整的图形编程源程序，可供图形编程者学习(A complete graphical programming source code available for graphics programmers to learn)

针对ANSYS开发的APDL，该命令流用于生成中国60kg钢轨，从而避免了繁琐的多曲线建模，十分方便。另外，基于该命令流，用户可以推演出更复杂的型面优化建模。(Developed for ANSYS APDL, the order flow is used to generate Chinese 60kg rails, thus avoiding the cumbersome multi-curve modeling, very convenient. In addition, based on the order flow, the user can deduce a more complex profile optimization modeling.)
