Syntax

Shape.getPathIterator(AffineTransform at, double flatness) has the following syntax.

PathIterator getPathIterator(AffineTransform at,    double flatness)

Example

In the following code shows how to use Shape.getPathIterator(AffineTransform at, double flatness) method.

import java.awt.Shape;
import java.awt.geom.PathIterator;
import java.awt.geom.Rectangle2D;
//from   w  w  w .java2s . c  om
public class Main {
  public static void main(String[] args) throws Exception {
    Shape s = new Rectangle2D.Double(0, 0, 72, 72);

    PathIterator pi = s.getPathIterator(null,2);

    while (pi.isDone() == false) {
      describeCurrentSegment(pi);
      pi.next();
    }

  }

  public static void describeCurrentSegment(PathIterator pi) {
    double[] coordinates = new double[6];
    int type = pi.currentSegment(coordinates);
    switch (type) {
    case PathIterator.SEG_MOVETO:
      System.out.println("move to " + coordinates[0] + ", " + coordinates[1]);
      break;
    case PathIterator.SEG_LINETO:
      System.out.println("line to " + coordinates[0] + ", " + coordinates[1]);
      break;
    case PathIterator.SEG_QUADTO:
      System.out.println("quadratic to " + coordinates[0] + ", " + coordinates[1] + ", "
          + coordinates[2] + ", " + coordinates[3]);
      break;
    case PathIterator.SEG_CUBICTO:
      System.out.println("cubic to " + coordinates[0] + ", " + coordinates[1] + ", "
          + coordinates[2] + ", " + coordinates[3] + ", " + coordinates[4] + ", " + coordinates[5]);
      break;
    case PathIterator.SEG_CLOSE:
      System.out.println("close");
      break;
    default:
      break;
    }
  }
}

The code above generates the following result.
