标题: 工业视觉 halcon图形window函数详细介绍
在halcon中，对图像操作时，时常还得针对窗口进行设置等，
图像是在窗口中显示，所以时常要设置窗口属性以满足图像处理结果显示。
这里我们接着介绍窗口相关函数。

open_window   close_window   clear_window
get_window_extents   set_window_extents    dump_window
dump_window_image   flush_buffer   copy_rectangle
query_window_type   get_window_type   set_window_type

get_window_attr   set_window_attr
update_window_pose   unproject_coordinates
get_disp_object_model_3d_info

get_os_window_handle  get_window_pointer3
set_window_dc  new_extern_window
