用于C/C++/Visual C 二二维等值线的绘制，程序源码 (Drawn for two two-dimensional contour of the C/C++/Visual C program source)

说明：  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.)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

本程序实现了计算机图形学的一些重要算法（画直线，画圆，画椭圆，区域填充，图形裁剪，齿轮生成，三次样条曲线等等），源码和可执行程序均打包于文件中(this program is implemented some important algorithm of computer graphics such as drawing lines,drawing circles,drawing ellipse,area filling,Graphics clipping，gear wheel generation ，three times spline curve and so on），source code and executable files are all included in the compressed file。 )

本程序是计算机图形学课程设计的程序，包含用各种算法绘制直线、圆、曲线，填充，剪裁等，有助于计算机图形学的学习与实践。(This procedure is a computer graphics curriculum design process, including the use of various algorithms to draw lines, circles, curves, filling, cutting, etc., help to learn and practice of computer graphics.)

教你如何使用画刷，MFC里面的画刷，文件里面是相关的代码。(tell you how to use the brush of MFC,there s the relative code inside the file.)

测绘方面的道路中桩计算程序。缓和曲线、圆曲线。(Surveying and mapping aspects of the road in the pile calculation program. Curve, the circular curve.)

产生一批随机数，使用TeeChart进行绘图。是TeeChart学习很好的程序。(Produce a random number, using TeeChart for drawing. TeeChart learning process is good.)

利用逐点法绘制出图形，图形的绘制其实都是由折线组成的，只是每条折线的误差太小了，肉眼根本分辨不出来(use of the point-by-point drawing graphics, the graphics are actually drawn from the composition of the dogleg, only broken each of error is too small, the human eye can not be seen)

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)
