DrawLine

利用C++实现的对杨辉三角形的模拟，可以在界面上打出杨辉三角形的内容。 (Achieved by C++ analog Triangle, Triangle content can be played on the interface.)

绘图程序，可以自由绘制直线、矩形、圆、多边形，可以设置颜色和宽度，并且能够进行图元基本操作，如剪裁、缩放及填充功能。(Drawing program, free to draw lines, rectangles, circles, polygons, you can set the color and width, and can be primitive basic operations, such as cropping, scaling and filling functions.)

CAD下VBA二次开发，用来展高程点，txt文件，已经把离散点网格化了(CAD lower VBA secondary development, to show elevation point, txt file, has the discrete points of the grid)

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)

open cascade 二维图形生成例子程序(open cascade two-dimensional graph of sample program)

随机生成一堆杂乱数据，借助RANSAC和贝塞尔样条拟合出曲线形状，使之最大程度拟合数据(Do the three degree Bezier Spline fitting based on RANSAC)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

说明：  几个常用的visio模具，想用的下载来用吧(Several commonly used Visio molds. Download them if you want to use them)

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)

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.)
