I have a BufferedImage and I want to get the RGB Data from it. The code
is written below, but I am not able to get what I want. Help is needed
and greatly appreciated.

    .....
    BufferedImage bi;
    width = bi.getWidth();
    height = bi.getHeight();
    cm = bi.getColorModel();
    Raster raster = bi.getRaster();
    DataBuffer dataBuffer = raster.getDataBuffer();
    int bank = raster.getNumBands();
    int dataType = raster.getTransferType();
    if (dataType != dataBuffer.TYPE_BYTE){
      throw new Exception("Unsupported Data Type!");
    }
    DataBufferByte dataBufferByte = (DataBufferByte) dataBuffer;
    if(bank == 1){
      pixels = (byte[]) dataBufferByte.getData().clone();
    }
    else if (bank == 3){
      RGBdata = new byte[3][width * height];
      RGBdata = dataBufferByte.getBankData();
    }
