public class LineSegment

extends java.lang.Object

Class to represent a single line segment.

Field Summary

RegionPixelStats	core_stats stats about the pixels contained within the line's core region
DPoint	direction
DPoint	end the other endpoint
EndPoint	endpoint1 the EndPoint object corresponding to start
EndPoint	endpoint2 the EndPoint object corresponding to end
int	id Its id - same ID as its corresponding quadric group
QuadricGroup	quads
DPoint	start one endpoint of the line
double	width the width, in pixels
RegionPixelStats	wing1_stats stats about the pixels contained in wing #1
RegionPixelStats	wing2_stats stats about the pixels contained in wing #2

Constructor Summary

LineSegment(int _id, DPoint p1, DPoint p2, double w, RegionPixelStats _core_stats, RegionPixelStats _wing1_stats, RegionPixelStats _wing2_stats, QuadricGroup qg)
create a new LineSegment with given id, start, end, and width

Method Summary
