C# 클래스 Accord.Math.Geometry.LineSegment

The class encapsulates 2D line segment and provides some tool methods related to lines.

The class provides some methods which are related to line segments: distance to point, finding intersection point, etc.

A line segment may be converted to a Line.

Sample usage:

// create a segment LineSegment segment = new LineSegment( new Point( 0, 0 ), new Point( 3, 4 ) ); // get segment's length float length = segment.Length; // get intersection point with a line Point? intersection = segment.GetIntersectionWith( new Line( new Point( -3, 8 ), new Point( 0, 4 ) ) );

공개 메소드들

메소드 설명
DistanceToPoint ( System.Point point ) : float

Calculate Euclidean distance between a point and a finite line segment.

Equals ( object obj ) : bool

Check if this instance of LineSegment equals to the specified one.

GetHashCode ( ) : int

Get hash code for this instance.

GetIntersectionWith ( Line other ) : Point?

Finds, provided it exists, the intersection point with the specified Line.

If the line and the segment do not intersect, the method returns . If the line and the segment share multiple points, the method throws an InvalidOperationException.

GetIntersectionWith ( LineSegment other ) : Point?

Finds, provided it exists, the intersection point with the specified LineSegment.

If the two segments do not intersect, the method returns . If the two segments share multiple points, this throws an InvalidOperationException.

LineSegment ( System.Point start, System.Point end ) : System

Initializes a new instance of the LineSegment class.

ToString ( ) : string

Get string representation of the class.

operator ( ) : bool

Equality operator - checks if two line segments have equal parameters.
