Example 3 with AztecEncoder

use of boofcv.alg.fiducial.aztec.AztecEncoder in project BoofCV by lessthanoptimal.

the class ExampleRenderAztecCode method main.

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);
