Class PolylineShape

java.lang.Object
  extended by com.lowagie.text.pdf.internal.PolylineShape
All Implemented Interfaces:
java.awt.Shape

public class PolylineShape
extends java.lang.Object
implements java.awt.Shape

Class that defines a Polyline shape. This class was originally written by wil - amristar.com.au and integrated into iText by Bruno.


Field Summary
protected  int np
          The total number of points.
protected  int[] x
          All the X-values of the coordinates in the polyline.
protected  int[] y
          All the Y-values of the coordinates in the polyline.
 
Constructor Summary
PolylineShape(int[] x, int[] y, int nPoints)
          Creates a PolylineShape.
 
Method Summary
 boolean contains(double x, double y)
          A polyline can't contain a point.
 boolean contains(double x, double y, double w, double h)
          A polyline can't contain a point.
 boolean contains(java.awt.geom.Point2D p)
          A polyline can't contain a point.
 boolean contains(java.awt.geom.Rectangle2D r)
          A polyline can't contain a point.
 java.awt.Rectangle getBounds()
          Returns the bounding box of this polyline.
 java.awt.geom.Rectangle2D getBounds2D()
          Returns the bounding box of this polyline.
 java.awt.geom.PathIterator getPathIterator(java.awt.geom.AffineTransform at)
          Returns an iteration object that defines the boundary of the polyline.
 java.awt.geom.PathIterator getPathIterator(java.awt.geom.AffineTransform at, double flatness)
          There's no difference with getPathIterator(AffineTransform at); we just need this method to implement the Shape interface.
 boolean intersects(double x, double y, double w, double h)
          Checks if one of the lines in the polyline intersects with a given rectangle.
 boolean intersects(java.awt.geom.Rectangle2D r)
          Checks if one of the lines in the polyline intersects with a given rectangle.
