DDA画线 中点画线 Bresenham画法

本人多年前一个工控项目的CAD,为别人用这个CAD制作界面文件，里面用到了绘图的多个方面，展示了图形和对象的交互-a CAD industrial projects and for others to use this interface CAD production of documents containing depleted in many areas of graphics display graphics and interactive object

一款用vc++编写的画图软件，本软件提供了画一些基本图形的功能，还有将图形进行填充。-vc with one prepared by the drawing software, the software provides a graphic pictures of some of the basic functions, there will be graphics for filling.

MSChart控件用于绘制各种图表，去持真正的三维绘图方式，支持所有主要的图表类型，数据点可以用条形图，折线图，填充区域图或饼形式显示。-Upstream control for drawing charts to hold the real 3D graphics, support for all major types of graphs, data points can be used bar charts, Plotting, filling regional map or cake form shows.

本程序实现八种图形的绘图功能，分别是直线，圆弧，贝赛尔曲线，矩形，圆角矩形，椭圆和多边形。绘图步骤如下： 直线：点鼠标左键确定起始点，移动鼠标点左键确定终点。 圆弧：用鼠标左键依次点四点确定圆弧。 贝赛尔曲线：用鼠标左键依次点四点确定贝赛尔曲线。 矩形：点左键确定起始点，拖动鼠标再点左键确定对角点。 圆角矩形：点左键确定起始点，拖动鼠标再点左键确定对角点。 椭圆：点左键确定起始点，拖动鼠标再点左键确定对角点，便作出了与该矩形相切的椭圆。 多边形：点鼠标左键确定起始点，然后依次点各点（所有点的总数为所要做多边形的边数，不超过20边），最后用中键确定，自动封闭图形。-the program eight graphical mapping function is linear, arc, Bessel curve, rectangle, rounded rectangle, oval and polygons. Mapping the following steps : Linear : click the mouse button to determine the threshold, mobile click of the mouse button to determine the end. Arc : the left mouse button followed by 4:00 set point arc. Bessel curve : the left mouse button followed by point 4:00 determine Bessel curve. Rectangular : Left to determine the threshold point, then drag the mouse to point to determine Left Corner. Rounded Rectangle : Left to determine the threshold point, then drag the mouse to point to determine Left Corner. Oval : Left to determine the threshold point, drag the mouse butto

查找所有二维平面上点的外轮廓的程序，采用opencv实现，是一个简单的学习图形学的工具-get all planar point on the outer contour of the procedures used opencv realized, is a simple tool for learning graphics
