Description
Returns intersection point of the two specified lines. parallel is true if the lines are parallel. intOnLines is true if the intersection is on both lines.
PROCEDURE LineLineIntersection(
l1start :POINT;
l1end :POINT;
l2start :POINT;
l2end :POINT;
VAR parallel :BOOLEAN;
VAR intOnLines :BOOLEAN;
VAR sectpt :POINT);
def vs.LineLineIntersection(l1start, l1end, l2start, l2end): return (parallel, intOnLines, sectpt)
Parameters
l1start POINT Start point of the first line l1end POINT End point of the first line l2start POINT Start point of the second line l2end POINT End point of the second line parallel BOOLEAN On return, true if the lines are parallel, false otherwise intOnLines BOOLEAN On return, true if the intersection point (if it exists) lies on both of the lines sectpt POINT On return, point of intersection of the lines, if the lines intersect
Example
VectorScript
PROCEDURE Example; VAR pt1, pt2, pt3, pt4, pt5 :POINT; parallel, intOnLines :BOOLEAN; BEGIN CallTool(-201); GetSegPt1(FSActLayer, pt1.x, pt1.y); GetSegPt2(FSActLayer, pt2.x, pt2.y); CallTool(-201); GetSegPt1(FSActLayer, pt3.x, pt3.y); GetSegPt2(FSActLayer, pt4.x, pt4.y); LineLineIntersection(pt1, pt2, pt3, pt4, parallel, intOnLines, pt5); Locus(pt5.x, pt5.y); END; RUN(Example);
