图形学画图,直线,圆,多边形,曲线,随手画,文本,裁剪(Graphics drawing straight lines, circles, polygons, curves, hand painting, text, cutting)

说明：  单文档绘图测试程序。单文档绘图测试程序。(single document mapping test. Single document mapping test.)

画曲线图的c++例子，使用定时器去随机数的方式画图。(Draw the curve c example, use the timer to go the way of the random number drawing.)

简单计算机图形学算法，通过直线中点Bresenham算法,绘制直线。( Simple computer graphics algorithms, Bresenham line passing through the midpoint algorithm, draw a straight line.)

当用户按下鼠标左键在如下图所示的面板上移动鼠标时，根据鼠标的移动轨迹在面板上画图。(When the user presses the left mouse button on the panel as shown in the following figure to move the mouse, according to the mouse movement trajectory in the panel drawing.)

本代码是进行齿轮参数设计和参数校核，参数化绘制二维工程图的源代码(gear parameters for the design and verification parameters, parametric mapping of two-dimensional engineering drawings source code)

MFC画图程序代码，可画椭圆，直线，矩形，改线宽，打开保存，颜色等(MFC drawing code can draw ellipses, lines, rectangles, change the line width, open the saved, color, etc.)

MFC画图程序,实现动态画直线、椭圆等功能(MFC drawing procedures, to achieve dynamic painting a straight line, oval and other functions)

关于三轴雕刻机用C语言实现，此为C方式下实现绘画CAD图。(About three-axis engraving machine with C language, this is C mode drawing CAD drawings.)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)
