Examples of WritableRaster

ae.java.awt.image.WritableRaster
This class extends Raster to provide pixel writing capabilities. Refer to the class comment for Raster for descriptions of how a Raster stores pixels.
The constructors of this class are protected. To instantiate a WritableRaster, use one of the createWritableRaster factory methods in the Raster class.
