represent a geometry segment line

Public Methods

Method	Description
Clone ( ) : Line2D	creates an instance of the GeometryLine class that is identical to the current GeometryLine
FindIntersection ( Line2D line0, Line2D line1 ) : int	find the number of intersection points for two segments
FindIntersection ( Line2D line0, Line2D line1, PointF &intersectPnt ) : int	find the intersection points of two segments
GetIntervalPoint ( float rate ) : PointF	get an interval point on the line of the segment
Line2D ( ) : System	constructor default StartPoint = (0.0, 0.0), EndPoint = (1.0, 0.0)
Line2D ( PointF startPnt, PointF endPnt ) : System	constructor
Scale ( float rate ) : void	scale the segment according to the center of the segment
Shift ( float distance ) : void	parallelly shift the line

Method	Description
CalculateBoundingBox ( ) : void	calculate BoundingBox according to StartPoint and EndPoint
