工业视觉halcon图形object函数详细介绍

图形对象可以是图像，区域或XLD形式，HALCON额外提供有很多函数与用户交互工作。
实现对图形对象的操作，然后再将操作的图形对象在后续中使用。
这些函数有：
attach_background_to_window  get_window_background_image
detach_background_from_window
create_drawing_object_circle  create_drawing_object_circle_sector
create_drawing_object_ellipse  create_drawing_object_ellipse_sector
create_drawing_object_line  create_drawing_object_rectangle1
create_drawing_object_rectangle2  create_drawing_object_text
create_drawing_object_xld  attach_drawing_object_to_window
detach_drawing_object_from_window  get_drawing_object_iconic
set_drawing_object_params  get_drawing_object_params
set_drawing_object_xld  clear_drawing_object
set_content_update_callback
set_drawing_object_callback
