一级标题c++ easyx简单矢量管理系统大一下课程设计

可以画点，线，圆，椭圆，矩形，多边形，折线。
画出图形的数据可保存在同文件夹下的txt文档中

填充功能要在同文件夹下放入名为image名称的jpg图片即可完成填充功能

代码如下
我是把设计的图形分为不同的类，用分文件编写 你也可放在同一个文件中。

这个矢量管理系统的填充功能需要在同文件夹下放一个图片 名字需要是image.jpg
jpg类型的图片

我的文件中是这个图片

大一以来写代码最长的一次，将近两千行。

有很多缺点就是，画图形只能先输入图形数据，然后再画出图形，画图界面与输入数据界面不能同时存在。

其中如果输入错误数据也可能使程序崩掉，也有许多的错误。

慢慢完善！
