intersection_segment_contour_xldintersection_segment_contour_xldIntersectionSegmentContourXldIntersectionSegmentContourXld (Operator)
Name
intersection_segment_contour_xldintersection_segment_contour_xldIntersectionSegmentContourXldIntersectionSegmentContourXld — Calculate the intersection points of a segment and an XLD contour
Signature
Herror intersection_segment_contour_xld(const Hobject Contour, double SegmentRow1, double SegmentColumn1, double SegmentRow2, double SegmentColumn2, double* Row, double* Column, Hlong* IsOverlapping)
Herror T_intersection_segment_contour_xld(const Hobject Contour, const Htuple SegmentRow1, const Htuple SegmentColumn1, const Htuple SegmentRow2, const Htuple SegmentColumn2, Htuple* Row, Htuple* Column, Htuple* IsOverlapping)
Description
intersection_segment_contour_xldintersection_segment_contour_xldIntersectionSegmentContourXldIntersectionSegmentContourXldIntersectionSegmentContourXld calculates the intersection points
of a segment and an XLD ContourContourContourContourcontour. The segment is defined by its
endpoints (SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1) and
(SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2).
The intersection points, if any, are returned in
(RowRowRowRowrow,ColumnColumnColumnColumncolumn).
If the segment and the XLD contour have a part in common
IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping returns the value 1, otherwise 0 is returned.
In this case the endpoints of the mutual
segment are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn).
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
