intersection_lines (Operator)

Name

intersection_lines — Calculate the intersection point of two lines

Signature

intersection_lines( : : Line1Row1, Line1Column1, Line1Row2, Line1Column2, Line2Row1, Line2Column1, Line2Row2, Line2Column2 : Row, Column, IsOverlapping)

Description

intersection_lines calculates the intersection point of two lines, which are defined by two of their points (Line1Row1,Line1Column1), (Line1Row2,Line1Column2), and (Line2Row1,Line2Column1), (Line2Row2,Line2Column2) respectively. The intersection point, if it exists, is returned in (Row,Column). If both lines are identical, IsOverlapping returns the value 1, otherwise 0 is returned. In this case no intersection point is returned in (Row,Column).
