Class DiskMemImageGraphics

java.lang.Object
  extended by java.awt.Graphics
      extended by java.awt.Graphics2D
          extended by org.jaitools.tiledimage.DiskMemImageGraphics

public class DiskMemImageGraphics
extends Graphics2D

A Graphics class for drawing into a DiskMemImage. As with JAI's TiledImageGraphics class, java.awt routines do the work and the purpose of this class is to serve the image data in a form that those routines can handle.

Most of the methods in this class are identical in function to those in Graphics2D; these have not been documented here.

clipRect

public void clipRect(int x,
                     int y,

getClip

public Shape getClip()

Note that if a transform has been applied the result of this method may only be approximately equal to the clip region originally set. This is because the clip region is stored internally in its transformed state, and the result of this method is calculated by applying the inverse of the transform to stored region.
