// or you can let it automatically select everything
AztecCode marker = new AztecEncoder().addAutomatic("Code 2D!").fixate();
// NOTE: The final function you call must be fixate(), that's how it knows it's done

// Render the marker as an image. It's also possible to render as a PDF or your own custom format

BufferedImage output = ConvertBufferedImage.convertTo(rendered, null);

// You can also save it to disk by uncommenting the line below
// UtilImageIO.saveImage(output, "aztec.png");

// Display the rendered marker
