Line2F

A 2D line geometric object defined by two 2D points.
Single precision.

Public Fields

p1	Point2F The end points of the line.
p2	Point2F The end points of the line.

Properties

AnyDefined readonly	System.Boolean True if either end point is defined
IsUndefined readonly	System.Boolean True if the line is undefined (i.e. if either end point is undefined).
Undefined static,readonly	Line2F An instance of an undefined line.

Methods

DistanceToLine	Double DistanceToLine (Point2F p) Finds the shortest distance between a point and the line. Parameters: p: The point to test. Returns: The shortest distance.
Intersect static	Line2F Intersect (Line2F A, Line2F B, Double tolerance) Return the intersection point of 2 lines Parameters: A: 1st test line. B: 2nd test line. Returns: The intersection point or Point2F.Undefined if the lines don't intersect.
Intersect static	Line2F Intersect (Line2F A, Line2F B)
Intersect static	Point2F Intersect (Line2F A, Point2F p, Vector2F v) Returns the intersection of a line and a uni-directional ray. Parameters: A: The line to test. p: End point of the ray. v: The ray direction vector. Returns:
IsInside	Boolean IsInside (Rect2F rect)
Length	Double Length () Calculate the length of the line segment Returns: The line length
NearestPoint	Point2F NearestPoint (Point2F p, Double& distance) Find the nearest point on the line to given point. Parameters: p: Returns:
NearestPoint	Point2F NearestPoint (Line2F line, Double& distance, Double tolerance)
Overlaps static	Point2F[] Overlaps (Line2F A, Line2F B, Double tolerance)
ProjectionIntersect static	Point2F ProjectionIntersect (Line2F A, Line2F B) Find the intersection of 2 bidirectional rays. Parameters: A: 1st ray (described by a line). B: 2nd ray (described by a line). Returns: The intersection point or Point2F.Undefined if the rays do not intersect (i.e. parallel).
RegionInside	Boolean RegionInside (Rect2F rect)
ToString	String ToString () String representation of the line. Returns: (X1,Y1)-(X2,Y2)
