public class Code2of5OrientationTest {

   @param args
   @throws BarcodeException 
   @throws ConfigurationException 
   @throws IOException 
  public static void main(String[] argsthrows ConfigurationException, BarcodeException, IOException {

    BarcodeUtil util = BarcodeUtil.getInstance();
    BarcodeGenerator gen = util.createBarcodeGenerator(buildCfg("2of5"));

    OutputStream fout = new FileOutputStream("2of5ori.jpg");
    int resolution = 200;
    int orientation = -270//Orientation must be 0, 90, 180, 270, -90, -180 or -270
    BitmapCanvasProvider canvas = new BitmapCanvasProvider(
        fout, "image/jpeg", resolution, BufferedImage.TYPE_BYTE_BINARY, false, orientation);

    gen.generateBarcode(canvas, "12345678");

  private static Configuration buildCfg(String type) {
    DefaultConfiguration cfg = new DefaultConfiguration("barcode");

    //Bar code type
    DefaultConfiguration child = new DefaultConfiguration(type);
      //Human readable text position
      DefaultConfiguration attr = new DefaultConfiguration("human-readable");
      DefaultConfiguration subAttr = new DefaultConfiguration("placement");
    return cfg;

It gives the following output,

CODE 2of5 Barcode
