生成简单的绘图工具windows forms(generate simple drawing tools)

说明：  1． 做一个集成的图形界面的程序，可调用每一次作业子程序。 2． 调用画点的函数，用DDA、中点算法画直线和中点算法及正负法画圆和抛物线。 3． 交互式的二维直线求交：如果存在交点，用实心圆显示交点，并用文字显示其坐标。 4． 用动画实现二维图形变换的各种算法，实现对指定形体的平移、旋转和缩放。（包括自行车行走和绕固定点旋转的自旋转物体动画。） 5． 线段裁剪和多边形裁剪算法的动画演示实现。（两种线段裁剪算法和H-S多边形逐边裁剪算法）多边形裁剪算法的动画演示要求先画出一个封闭的多边形，再画矩形的裁剪窗口，然后选择裁剪按钮（或命令），按下“上边裁剪”按钮（或执行“上边裁剪”命令），多边形相对裁剪窗口的上边进行裁剪，显示上边裁剪后的多边形，依此进行其它各边裁剪。 6． 两种扫描多边形扫描转换算法实现（扫描线算法为必做，基于求余运算的边缘填充和边标志算法任选一种）； 7． 4连通区域的递归种子填充算法，和扫描线种子填充算法，要求种子点(x,y)可交互输入）。 8． 简单三维图形系统：凸多面体的建模、透视投影，隐藏面的消除及基本图形变换（平移、旋转、缩放）。 9． 交互式Bezier曲线的输入绘制程序实现 (1. So an integrated graphical interface procedures, which call for each operation subroutine. 2. Calling the painting point function, with DDA, the midpoint algorithm painting line and the midpoint algorithm and France Circle and the positive and negative parabola. 3. Interactive 2D linear intersection : If there intersection with a solid circle indicates Nodal and writing to demonstrate its coordinates. 4. Using 2D animation graphics transform algorithms to achieve the specified physical translation, rotation and scaling. (Including walking and cycling around the fixed point of rotating objects from the rotating animation.) 5. Line cutting and polygon clipping algorithm to achieve the animation demo. (Two segments cutting algorithm and H-S-by-side polygon clipping algorithm) polygon clipp)

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.)
