-------------------------方式一
read_image (Image, 'E:/Halcon数据/资源图片/左.bmp')
//创建一个可以交互修改的圆。此圆仅作为初始位置，后期可拖拽修改
create_drawing_object_circle (2120, 3030, 180, DrawID)
//设置颜色
set_drawing_object_params (DrawID, 'color', 'green')
//将现有绘图对象附加到 HALCON 窗口
attach_drawing_object_to_window (WindowHandle, DrawID)
绿色状态表示可拖拽修改
*获取联动区域
get_drawing_object_iconic (Object, DrawID)
//取消绑定
detach_drawing_object_from_window (WindowHandle, DrawID1)
detach_background_from_window (WindowHandle)
//显示目标区域
reduce_domain (Image, Object, ImageReduced)
-------------------------方式二
//此种方式没有初始位置，需要直接在窗口画区域
draw_rectangle2 (WindowHandle, Row, Column, Phi, Length1, Length2)
//修改区域
draw_rectangle2_mod (WindowHandle, Row, Column, Phi, Length1, Length2, Row1, Column1, Phi1, Length11, Length21)
//显示目标区域
dev_set_draw ('margin')
gen_rectangle2 (Rectangle, Row1, Column1, Phi1, Length11, Length21)
