Elliptic-Curve-Encryption-Algorithm

用MFC实现画图板，包括绘线，几何图形，上色等等，简单易懂。(To realize drawing board with MFC)

Gompertz（龚伯次）曲线模型被广泛应用在预测中，该代码实现了G曲线的预测功能。(Gompertz curve is widely used in prediction, this code will help achieve the Gompertz curve prediction function.)

可以画图的功能强大cad软件一定不要错过你值得拥有制图高级工具(You can paint the powerful CAD software must not miss you worthy of drawing advanced tools )

说明：  MFC坐标系的绘制，动态显示曲线，感兴趣的可以参考下~~(MFC frame rendering, dynamic display curves of interest can refer to the following ~ ~)

根据图框块自动识别图纸并预览打印。函数参数分别为：打印机名称，打印样式，打印纸张，打印份数，自动纸张，自动旋转，自动关闭，自动识别图框(Autoprint according to the drawing blocks.)

说明：  用VC++编写，MFC文档框架，是一个简易的画图小程序，在文档界面上画图(With VC++ Prepared, MFC framework document is a simple drawing of small procedures, the document interface drawing)

分形几何是数学领域里新兴的课题,如果将图形的每个元素按某种规则进行变形,得到新的图形,以此类推,进行若干次变形后得到的图形就是分形图形。本程序实现分形图。(Fractal geometry is the mathematical field of emerging issues, if the graphics of each element according to certain rules of deformation, new graphics, and so on, to carry out a number of graphics after deformation is fractal graphics. This procedure realize fractals.)

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.)

off 转stl ，很好的转换软件源码。实现了off三维格式向stl三维格式转换，可用于CAD、ProE等软件对接。( Turn off to stl, good conversion software source code. Off to achieve a three-dimensional format stl three-dimensional format conversion, it can be used in CAD, ProE and other software docking.)
