Name

Description

intersection_line_contour_xldintersection_line_contour_xldIntersectionLineContourXldIntersectionLineContourXldIntersectionLineContourXld calculates the intersection points of a line and an XLD ContourContourContourContourcontour. The line is defined by the points (LineRow1LineRow1LineRow1LineRow1lineRow1,LineColumn1LineColumn1LineColumn1LineColumn1lineColumn1) and (LineRow2LineRow2LineRow2LineRow2lineRow2,LineColumn2LineColumn2LineColumn2LineColumn2lineColumn2). The intersection points, if any, are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn). If a part of the XLD contour lies on the line IsOverlappingIsOverlappingIsOverlappingIsOverlappingisOverlapping returns the value 1, otherwise 0 is returned. In this case the endpoints of the XLD segment are returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn).
