import java.awt.image.DataBufferByte; //导入方法依赖的package包/类
/**
* Constructs a BytePackedRaster with the given SampleModel,
* DataBuffer, and parent. DataBuffer must be a DataBufferByte and
* SampleModel must be of type MultiPixelPackedSampleModel.
* 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.
*
* @exception RasterFormatException if the parameters do not conform
* to requirements of this Raster type.
