public ByteComponentRaster ( SampleModel sampleModel , Point origin ) { this ( sampleModel , sampleModel . createDataBuffer ( ) , new Rectangle ( origin . x , origin . y , sampleModel . getWidth ( ) , sampleModel . getHeight ( ) ) , origin , null ) ; }
constructs a bytecomponentraster with the given samplemodel . the raster ' s upper left corner is origin and it is the same size as the samplemodel . a databuffer large enough to describe the raster is automatically created . samplemodel must be of type singlepixelpackedsamplemodel or componentsamplemodel .
