Description

intersection_segment_lineintersection_segment_lineIntersectionSegmentLineIntersectionSegmentLineIntersectionSegmentLine calculates the intersection point of a segment and a line. The segment is defined by its endpoints (SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1) and (SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2). The line is defined by the two points (LineRow1LineRow1LineRow1LineRow1lineRow1,LineColumn1LineColumn1LineColumn1LineColumn1lineColumn1) and (LineRow2LineRow2LineRow2LineRow2lineRow2,LineColumn2LineColumn2LineColumn2LineColumn2lineColumn2). The intersection point, if it exists, is returned in (RowRowRowRowrow,ColumnColumnColumnColumncolumn). If the segment and the line 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).
