## Description

Calculates the intersection between the specified line and ellipse.

PROCEDURE LineEllipseIntersect(

a1 :POINT;

a2 :POINT;

upperRight :POINT;

lowerLeft :POINT;

VAR int1 :POINT;

VAR legal1 :BOOLEAN;

VAR int2 :POINT;

VAR legal2 :BOOLEAN);

def vs.LineEllipseIntersect(a1, a2, upperRight, lowerLeft): return (int1, legal1, int2, legal2)

## Parameters

a1 POINT Start point of the line a2 POINT End point of the line upperRight POINT Upper-right point of the ellipse lowerLeft POINT Lower-left point of the ellipse int1 POINT On return, first point of intersection, if found legal1 BOOLEAN On return, second point of intersection, if found int2 POINT On return, indicates that int1 is a valid point of intersection legal2 BOOLEAN On return, indicates that int2 is a valid point of intersection

## Remarks

On return, int1 and int2 are the two possible points of intersection. legal1 and legal2 indicate if the intersections are actually valid.
