        //Instantiage BarCodeGenerator object
        BarCodeGenerator barCodeGenerator = new BarCodeGenerator(settings);
        //Generate image data based on settings and save it to BufferedImage instance
        BufferedImage bufferedImage = barCodeGenerator.generateImage();
        //Save the Barcode as PNG
        ImageIO.write(bufferedImage, "png", new File("Codabar.png"));
    }
}
