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

java.awt.image.IndexColorModel.createCompatibleWritableRaster()
Creates a WritableRaster with the specified width and height that has a data layout (SampleModel) compatible with this ColorModel. This method only works for color models with 16 or fewer bits per pixel.
Since IndexColorModel can be subclassed, any subclass that supports greater than 16 bits per pixel must override this method. @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 the number of bits in apixel is greater than 16 @see WritableRaster @see SampleModel
