Description: 程序的功能：
一、用两种不同算法（DDA法和中点法）画任意直线，输入方式有鼠标取点点法，和对话框输入直线端点法。直线颜色在画线前任意选取。
二、直线的属性控制。可以从对话框中任意输入线宽画直线。还有画虚线的功能，你可以输入虚线中实线部分的长度和空白间隔的长度来画虚线。
三、用两种算法（中点法和正负法）画任意圆。
四、画任意椭圆。画椭圆时限任意取两点确定一矩形，由该矩形确定椭圆的大小。
五、多边形填充。用鼠标取点画任意多边形，可选取任意颜色去填充多边形区域。
六、矩形填充。用鼠标任取两点确定矩形区域，选取任意颜色去填充。
七、直线裁剪。有两种算法实现这一功能,梁友栋法和编码法。先用鼠标画一直线，然后再取两点确定一矩形裁剪框，点击一下右键，裁剪成功。
八、多边形裁剪。先用鼠标取点画一任意多边形，点击右键后继续取两点确定裁剪矩形框，在点击一次右键裁剪执行。
九、弹球。-procedures functions : one, using two different algorithms (DDA law and midpoint) painting arbitrary line, input from a little mouse, and the dialog box input linear endpoint law.

Description: 一个集成的图形界面的程序，可调用每一次作业子程序。一、调用画点的函数，用DDA、中点算法画直线和中点算法画圆和椭圆。二、多边形扫描转换算法和区域填充算法实现（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为任选；基于种子的区域填充采用4连通区域的递归种子填充算法，或扫描线种子填充算法，要求种子点(x,y)可交互输入）。三、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。四、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。（包括类似自行车行走和绕固定点旋转的自旋转物体动画。）五、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）。六、交互式Bezier曲线的输入绘制程序实现-An integrated graphical interface program, can call the subroutine each operation.
