Question about JAI posted example?

Question

Thank you
I just wondered if I could ask, I found this example JAI code on the web. The code compiles, but in the example said they missed out some lines at the begining, do you these missing lines were to read-in a image?
import java.awt.*;
import java.awt.image.*;
import javax.media.jai.*;
public class CreateRGBImage{
   public static void main(String[] args){
      int width = 121; int height = 121; // Dimensions of the image
      byte[] data = new byte[width*height*3]; // Image data array.
      int count = 0; // Temporary counter.
      for(int w=0;w<width;w++) // Fill the array with a pattern.
         for(int h=0;h<height;h++){
            data[count+0] = (count % 2 == 0) ? (byte)255: (byte) 0;
            data[count+1] = 0;
            data[count+2] = (count % 2 == 0) ? (byte) 0: (byte)255;
            count += 3;
      // Create a Data Buffer from the values on the single image array.
      DataBufferByte dbuffer = new DataBufferByte(data,width*height*3);
      // Create an pixel interleaved data sample model.
      SampleModel sampleModel = RasterFactory.
      createPixelInterleavedSampleModel(DataBuffer.TYPE_BYTE,
      width,height,3);
      // Create a compatible ColorModel.
      ColorModel colorModel = PlanarImage.createColorModel(sampleModel);
      // Create a WritableRaster.
      Raster raster = RasterFactory.createWritableRaster(sampleModel,dbuffer,
      new Point(0,0));
      // Create a TiledImage using the SampleModel.
      TiledImage tiledImage = new TiledImage(0,0,width,height,0,0,
      sampleModel,colorModel);
      // Set the data of the tiled image to be the raster.
      tiledImage.setData(raster);
      // Save the image on a file.
      JAI.create("filestore",tiledImage,"rgbpattern.tif","TIFF");
}

I didnot go thru the code you posted but I know that the following workstry {
        // From file
        AudioInputStream stream = AudioSystem.getAudioInputStream(new File("audiofile"));
        // From URL
        stream = AudioSystem.getAudioInputStream(new URL("http://hostname/audiofile"));
        // At present, ALAW and ULAW encodings must be converted
        // to PCM_SIGNED before it can be played
        AudioFormat format = stream.getFormat();
        if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
            format = new AudioFormat(
                    AudioFormat.Encoding.PCM_SIGNED,
                    format.getSampleRate(),
                    format.getSampleSizeInBits()*2,
                    format.getChannels(),
                    format.getFrameSize()*2,
                    format.getFrameRate(),
                    true);        // big endian
            stream = AudioSystem.getAudioInputStream(format, stream);
        // Create the clip
        DataLine.Info info = new DataLine.Info(
            Clip.class, stream.getFormat(), ((int)stream.getFrameLength()*format.getFrameSize()));
        Clip clip = (Clip) AudioSystem.getLine(info);
        // This method does not return until the audio file is completely loaded
        clip.open(stream);
        // Start playing
        clip.start();
    } catch (MalformedURLException e) {
    } catch (IOException e) {
    } catch (LineUnavailableException e) {
    } catch (UnsupportedAudioFileException e) {
    }
