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).
