说明：  mfc下绘出样条曲线，并根据样条曲线对其上的值进行差值。(mfc-spline curves plotted under and in accordance with spline curve on the value of their difference.)

cad文本输入，适合宗地号输入。地籍测绘作业宗地号预编使用。(cad text input, suitable parcel number input.Cadastral mapping operations parcel number pre-programmed to use.)

MFC做的画图软件 只能画直线 还有待改进 适合初学者 看看(MFC do draw a straight line drawing software can be improved for beginners look)

很好的齿轮cad参数化设计程序，能够进行直齿轮和斜齿轮的参数化设计和cad绘图输出(Cad good gear parametric design process, can spur gear and helical gear parametric design and cad graphics output)

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。 )

实现从SDK到MFC的封装 增加了绘制线条 矩形 椭圆等功能 而且可以变换颜色(none sdk to mfc)

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.)

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)

这是一个模拟acdsee软件打开一幅bmp文件并显示在屏幕上的算法.(This is a simulation software Converter opened a bmp file and display on the screen of the algorithm.)
