Examples of LineSegment

com.vividsolutions.jts.geom.LineSegment
Represents a line segment defined by two {@link Coordinate}s. Provides methods to compute various geometric properties and relationships of line segments.
This class is designed to be easily mutable (to the extent of having its contained points public). This supports a common pattern of reusing a single LineSegment object as a way of computing segment properties on the segments defined by arrays or lists of {@link Coordinate}s. @version 1.7
dwlab.shapes.line_segments.LineSegment
It's line section between 2 pivots (sprites centers).
gnu.java.awt.java2d.LineSegment
org.geomajas.gwt.client.spatial.LineSegment
Representation of a LineSegment, mainly for mathematical purposes. Can calculate much needed line to line and line to point calculations. @author Pieter De Graef
