Examples of java.awt.image.ColorModel.createCompatibleWritableRaster()

java.awt.image.ColorModel.createCompatibleWritableRaster()
Creates a WritableRaster with the specified width and height that has a data layout (SampleModel) compatible with this ColorModel. Since ColorModel is an abstract class, any instance is an instance of a subclass. Subclasses must override this method since the implementation in this abstract class throws an UnsupportedOperationException. @param w the width to apply to the new WritableRaster @param h the height to apply to the new WritableRaster @return a WritableRaster object with the specifiedwidth and height. @throws UnsupportedOperationException if thismethod is not supported by this ColorModel @see WritableRaster @see SampleModel
