Description

intersection_contours_xldintersection_contours_xldIntersectionContoursXldIntersectionContoursXldIntersectionContoursXld calculates the intersection points of the XLD Contour1Contour1Contour1Contour1contour1 and XLD Contour2Contour2Contour2Contour2contour2 which, if any, are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn). The value in IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType defines the way to calculate the intersections points. By setting IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'self'"self""self""self""self", only the self intersections within both contours are returned, i.e., the intersections within Contour1Contour1Contour1Contour1contour1 and XLD Contour2Contour2Contour2Contour2contour2. For IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'mutual'"mutual""mutual""mutual""mutual", only the intersections between both contours are taken into account. The default value is IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType = 'all'"all""all""all""all". In this case both, the self and the mutual intersections are returned in RowRowRowRowrow,ColumnColumnColumnColumncolumn). If parts of the contours overlap in more than one point IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping returns the value 1, otherwise 0 is returned. IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping is set with regard to both the self and mutual overlap, regardless of the setting in IntersectionTypeIntersectionTypeIntersectionTypeIntersectionTypeintersectionType. In case of a mutual overlap, the endpoints of the mutual segment are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn).
