- 關于顯示類函數解釋
dev_update_window (‘off’)
read_image (Image, ‘plastic_mesh/plastic_mesh_01’)
dev_close_window ()
get_image_size (Image, Width, Height)
dev_open_window_fit_image (Image, 0, 0, Width, Height, WindowHandle)
set_display_font (WindowHandle, 18, ‘mono’, ‘true’, ‘false’)
dev_set_draw (‘margin’)
dev_set_line_width (3)

endfor
處理思路
這個例子是主要講解了動態閾值在缺陷檢測中的應用。

大家有什么問題可以向我提問哈，我看到了第一時間回復，希望在學習的路上多多結交良師益友。
