MFC-drawing

该程序实现圆拟合，对学习圆拟合有一定帮助。(circle fit based on VC++)

AE实现加载CAD格式的数据，以及对其进行转换格式，转换为SHP等格式，还有对其进行编辑等操作(AE spatial data editing functions, including generating points, generating lines, as well as delete, move elements such as fried operation)

解析法面积计算,读数据文件,计算后生成结果文件,任意多边形的顶点坐标,然后 计算出面积是平方米和公顷(analytical calculation, reading data files, calculation results generated documents, arbitrary polygon vertices, then compute the area of square meters and ha)

这个程序是用Breseham画法在visual c++平台下画直线和圆。可以对图像进行刷新，画多条直线，多个圆(This procedure is used Breseham paint in visual c++ platform for the next drawing a straight line and circle. Can refresh the image, painted more than a straight line, a number of round)

改进的Bresenham算法，用visual c++ 实现(Improved Bresenham algorithm, using visual c++ achieve)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

使用MFC创建单文档程序，在界面上画圆，单击可使圆放大、变色(MFC SDI DRAW CIRCLE, CLICK TO INFLATE THE CIRCLE AND CHANGE ITS COLOR)

Teechart绘图应用实例（随机线条、动态画线、画圆）(Teechart drawing application examples (random lines, dynamic draw lines, circle))

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.)

三次bezier曲线的绘制（其中调用pow（））。(The drawing of cubic Bezier curve (where pow ()).)
