Returns a BufferedImage with a data layout and color model compatible with this GraphicsConfiguration. This method has nothing to do with memory-mapping a device.

Returns the default AffineTransform for this GraphicsConfiguration. This AffineTransform is typically the Identity transform for most normal screens. The default AffineTransform maps coordinates onto the device such that 72 user space coordinate units measure approximately 1 inch in device space. The normalizing transform can be used to make this mapping more exact. Coordinates in the coordinate space defined by the default AffineTransform for screen and printer devices have the origin in the upper left-hand corner of the target region of the device, with X coordinates increasing to the right and Y coordinates increasing downwards. For image buffers not associated with a device, such as those not created by createCompatibleImage, this AffineTransform is the Identity transform.

Returns an AffineTransform that can be concatenated with the default AffineTransform of a GraphicsConfiguration so that 72 units in user space equals 1 inch in device space. 
 For a particular Graphics2D, g, one can reset the transformation to create such a mapping by using the following pseudocode:

     g.setTransform(gc.getDefaultTransform());
     g.transform(gc.getNormalizingTransform());

 Note that sometimes this AffineTransform is identity, such as for printers or metafile output, and that this AffineTransform is only as accurate as the information supplied by the underlying system. For image buffers not associated with a device, such as those not created by createCompatibleImage, this AffineTransform is the Identity transform since there is no valid distance measurement.
