8.1 Acquiring the image data of the trajectory
Get contour coordinates get_contour_xld
Operator: get_contour_xld(Contour : : : Row, Col)
Example: get_contour_xld(Contours4, Row26, Col)
Contours4 (input object): input contour object
Row26 (output control parameter 1): output the row coordinates of each point of the contour
Col (output control parameter 2): the ordinate of each point of the output contour
8.2 Save and read the profile
Save contour: save the contour as a DXF file write_contour_xld_dxf
Operator: write_contour_xld_arc_info(Contours : : FileName : )
Example: write_contour_xld_arc_info(Contours4, '119')
Contours4 (input object): input contour object
119 (input control parameters): input file name
Read Contours: Read DXF files into read_contour_xld_dxf
Operator: read_contour_xld_arc_info( : Contours : FileName : )
Example: read_contour_xld_arc_info(Contours4, '112')
Contours4 (output object): output contour object
112 (input control parameters): input file name
8.3 Set Operations of Contours
Intersection of closed contours: intersection_closed_contours_xld
算子：intersection_closed_contours_xld(Contours1, Contours2 : ContoursIntersection : : )
示例：intersection_closed_contours_xld (ContEllipse, ContEllipse1, ContoursIntersection1)
ContEllipse(input object 1): input contour object 1
ContEllipse1 (input object 2): input contour object 2
ContoursIntersection1 (output object): Output the contours of the intersecting part of two contour objects
Difference of closed contours: difference_closed_contours_xld
算子：difference_closed_contours_xld(Contours, Sub : ContoursDifference : : )
示例：difference_closed_contours_xld (ContEllipse, ContoursIntersection1, ContoursDifference)
ContEllipse (input object 1): input larger contour object
ContoursIntersection1 (input object 2): input small contour objects
ContoursDifference (output object): output the contour object after subtraction
