示例1: ByteBandedRaster

import java.awt.image.DataBufferByte; //導入方法依賴的package包/類
/**
 *  Constructs a ByteBandedRaster with the given sampleModel,
 *  DataBuffer, and parent. DataBuffer must be a DataBufferShort and
 *  SampleModel must be of type BandedSampleModel.
 *  When translated into the base Raster's
 *  coordinate system, aRegion must be contained by the base Raster.
 *  Origin is the coordinate in the new Raster's coordinate system of
 *  the origin of the base Raster.  (The base Raster is the Raster's
 *  ancestor which has no parent.)
 *
 *  Note that this constructor should generally be called by other
 *  constructors or create methods, it should not be used directly.
 *  @param sampleModel     The SampleModel that specifies the layout.
 *  @param dataBuffer      The DataBufferShort that contains the image data.
 *  @param aRegion         The Rectangle that specifies the image area.
 *  @param origin          The Point that specifies the origin.
 *  @param parent          The parent (if any) of this raster.
