Halcon画线闪烁问题

1. * Image Acquisition 01: Code generated by Image Acquisition 01
   
2. open_framegrabber ('DirectShow', 1, 1, 0, 0, 0, 0, 'default', 8, 'rgb', -1, 'false', 'default', '[0] Integrated Camera', 0, -1, AcqHandle)
   
3. grab_image_start (AcqHandle, -1)
   
4. * set_system ('flush_graphic', 'false')

6. while (true)
   
7.     * Image Acquisition 01: Do something
   
8. 
   
9.     grab_image_async (Image, AcqHandle, -1)
   
10.     dev_get_window(windowhandle)
    
11.     disp_line(windowhandle,10,100,10,200)
    
12. 
    
13. *     wait_seconds(0.05)
    
14. *     set_system ('flush_graphic', 'true')

16. endwhile
    
17. close_framegrabber (AcqHandle)

用disp_line方法画了一条线，当开始运行程序时发现那条线一直闪烁。请教一下，在视频采集中画的线，如何设置才能不闪烁？
已经尝试了set_system ('flush_graphic', 'true')方法和dev_update_window('off')方法，不能解决。

1. dev_get_window (WindowHandle)
   
2. set_window_param (WindowHandle, 'flush', 'false')
   
3. while(true)
   
4.     read_image (Image, 'printer_chip/printer_chip_01')
   
5.     * Image Acquisition 01: Do something  
   
6.     dev_display (Image)
   
7.     disp_line(WindowHandle,10,100,10,200)
   
8.     flush_buffer (WindowHandle)
   
9. endwhile
