Matlab鼠标画图,用pop-up menu选择画图标记,颜色edit记录鼠标坐标

但是功能比较简单，只能画线，不能画矩形、椭圆等



其中一个难点就是：拖动鼠标的过程中如何显示矩形/椭圆的轮廓，并且轮廓跟着鼠标指针移动。

程序的亮点：

1、可选择点、线、矩形、椭圆进行画图；

2、可选择marker、LineTyple进行画图；

3、可选择画图颜色；

4、可实时显示鼠标指针当前坐标；

5、可清除画板；

6、可保存画好的图(bmp、jpg、gif)；

7、操作比较人性化，模仿了windows画板；

8、该程序牵涉的面广，是一个很好的GUI学习资料。

-Matlab mouse drawing, with the pop-up menu select the drawing marks, color edit record mouse coordinates, but relatively simple function, can only draw a line, not drawing rectangles, ellipses, etc. One of the difficulties is this: how the process of dragging the rectangle/oval contours, and outline follow the mouse pointer moves. Program Highlights: 1, select point, line, rectangle, ellipse for drawing　2, optional marker, LineTyple the drawing　3, choose paint colors　4, real-time display the current coordinates of the mouse pointer　5, to clear the drawing board　 6, save-drawn map (bmp, jpg, gif)　7, operation more user-friendly, imitating the windows drawing board　8, the program involved a wide range, the GUI is a good learning materials.
