Description

intersection_contours_xldintersection_contours_xldIntersectionContoursXldintersection_contours_xldIntersectionContoursXldIntersectionContoursXld calculates the intersection points of the XLD Contour1Contour1Contour1Contour1Contour1contour1 and XLD Contour2Contour2Contour2Contour2Contour2contour2 which, if any, are returned in (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn). The value in IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType defines the way to calculate the intersections points. By setting IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'self'"self""self""self""self""self", only the self intersections within both contours are returned, i.e., the intersections within Contour1Contour1Contour1Contour1Contour1contour1 and XLD Contour2Contour2Contour2Contour2Contour2contour2. For IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'mutual'"mutual""mutual""mutual""mutual""mutual", only the intersections between both contours are taken into account. The default value is IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'all'"all""all""all""all""all". In this case both, the self and the mutual intersections are returned in RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn). If parts of the contours overlap in more than one point IsOverlappingIsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping returns the value 1, otherwise 0 is returned. IsOverlappingIsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping is set with regard to both the self and mutual overlap, regardless of the setting in IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType. In case of a mutual overlap, the endpoints of the mutual segment are returned in (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn).
