gen_image_const (Image, 'byte', 512, 512)
    get_domain (Image, Domain)
    paint_region (Domain, Image, ImageResult1, 100, 'fill')
    gen_rectangle1 (ROI_0, 204.77, 124.164, 278.986, 347.643)
    
    paint_region (ROI_0, ImageResult1, ImageResult, 255, 'fill')
    
    
    binary_threshold (ImageResult, Region, 'max_separability', 'light', UsedThreshold)
    
    *已知矩形 求矩形四个顶点坐标
    **方法一
    get_region_polygon (Region, 5, Rows, Columns)
    gen_cross_contour_xld (Cross, Rows, Columns, 60, 0.785398)
    **方法二
    gen_contour_region_xld (Region, Contours, 'border')
    gen_polygons_xld (Contours, Polygons, 'ramer', 2)
    get_polygon_xld (Polygons, Row, Col, Length, Phi)
    gen_cross_contour_xld (Cross, Row, Col, 60, 0.785398)
    **
    get_lines_xld (Polygons, BeginRow, BeginCol, EndRow, EndCol, Length1, Phi1)
    *********
    **方法三
    smallest_rectangle2 (Region, Row2, Column1, Phi3, Length12, Length21)
    gen_rectangle2_contour_xld (Rectangle, Row2, Column1, Phi3, Length12, Length21)
    get_contour_xld (Rectangle, Row3, Col1)
    gen_cross_contour_xld (Cross1, Row3, Col1, 60, Phi1)
