question: public IntegerInterleavedRaster ( SampleModel sampleModel , DataBuffer dataBuffer , Point origin ) { this ( sampleModel , dataBuffer , new Rectangle ( origin . x , origin . y , sampleModel . getWidth ( ) , sampleModel . getHeight ( ) ) , origin , null ) ; }
target:  Constructs a IntegerInterleavedRaster with the given SampleModel and DataBuffer.  The Raster's upper left corner is origin and it is the same sizes the SampleModel.  The DataBuffer is not initialized and must be a DataBufferInt compatible with SampleModel. SampleModel must be of type SinglePixelPackedSampleModel.
