说明：  一个Visual Graph开发程序，具有类似MS viso的功能！带有C++,Delphi,VB,C#等的代码示例！(a Visual Graph development programs that have similar functions VISO MS! With C, Delphi, VB, C# code examples!)

本程序主要是利用NI公司提供的measurement studio控件画曲线，从文件中提取数据，通过定时器动态显示在对话框上。(This procedure is the use of NI offers measurement studio control to draw curves to extract data from the file, through the dynamic timer is displayed in the dialog box.)

实现了DDA直线生成算法画直线，Bresenham圆弧生成算法画圆弧(Achieve DDA line drawing algorithm to generate a straight line, Bresenham algorithm for drawing arcs arc generated)

dxflib-3.3.4-src ，dxflib是一个用来读写DXF文件的C++库。当读DXF文件的时候,dxflib分析文件并且调用用户自己定义的函数来添加实体、层、等。(dxflib-3.3.4-src，dxflib is an opensource C++ library for reading and writing AutoCAD (R) DXF files. )

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.)

在AutoCAD中添加一个自定义分页侧边栏。(In AutoCAD add a custom tab sidebar.)

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

MFC下实现DDA算法、一般直线的Bresenham算法、Bresenham画圆算法 、中点圆整数优化(MFC DDA Bresenham )

说明：  图形绘制，可设置线宽、颜色、样式，通过本例将了解如何使用自定义画笔定义线体的颜色，线宽，线形等，以及如何为程序中添加选项菜单和选项设置对话框，如何使用标准颜色对话框，如何使用字体对话框，在选项对话框中实现预览功能。实现选项对话框和窗口类中的数据交换。如何改变对话框和控件的背景色，如何改变控件的文本颜色，对按钮控件的特殊处理。如何在窗口中显示一幅位图。(VC++ graphics rendering, can set the line width, color, style, through this example will learn how to use custom brushes defined line of body color, line width, line, etc., and how to add options for the program menus and options in Settings dialog box How to use the standard color dialog box, how to use the Font dialog box, implemented in the Options dialog box preview. Implementation Options dialog box and window class data exchange. How to change the background color of dialog boxes and controls, how to change the control' s text color on button controls the special treatment. How in the window display a bitmap.)

用VS2012和open cv2.47编写的一个简单画图板程序，可以像画图板一样用鼠标画任意图形(Using VS2012 and open cv2.47 drawing board to write a simple program, you can use the mouse as the drawing board, like any graphic painting)
