read_image (Image1, 'C:/Users/haokunlee/Desktop/《halcon機器視覺教程》素材及程序/7-5/1.bmp')
rgb1_to_gray (Image1, GrayImage)

draw_rectangle1 (WindowHandle, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
smallest_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)
gen_rectangle2_contour_xld (Rectangle1, Row, Column, Phi, Length1, Length2)

*創建xld模板
create_shape_model_xld (Rectangle1, 'auto', -0.2, 0.2, 0.01, 'auto', 'ignore_local_polarity', 5, ModelID)
