public class ExampleRenderAztecCode {
	public static void main( String[] args ) {
		// Create a marker to render. Almost everything about how the marker is constructed can be manually specified
		// 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
		GrayU8 rendered = AztecGenerator.renderImage(/* pixel per square */ 10, /* border squares */ 1, marker);

		// Convert it to a BufferedImage for display purposes
		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
		ShowImages.showWindow(output, "Rendered Aztec Code", true);
