Example 3 with QrCodeEncoder

use of boofcv.alg.fiducial.qrcode.QrCodeEncoder in project BoofCV by lessthanoptimal.

the class ExampleRenderQrCode method main.

public static void main(String[] args) {
    // Uses a flow pattern to specify the QR Code. You can control all aspects of the QR
    // like specifying the version, mask, and message types or let it select all of that for you.
    QrCode qr = new QrCodeEncoder().setError(QrCode.ErrorLevel.M).addAutomatic("This is a Test ん鞠").fixate();
    // NOTE: The final function you call must be fixate() that's how it knows its done
    // QrCodeGenerator is the base class with all the logic and the children tell it how to
    // write in a specific format. QrCodeGeneratorImage is included with BoofCV and is used
    // to creates images
    QrCodeGeneratorImage render = new QrCodeGeneratorImage(20);
    render.render(qr);
    // Convert it to a BufferedImage for display purposes
    BufferedImage image = ConvertBufferedImage.convertTo(render.getGray(), null);
    ShowImages.showWindow(image, "Rendered QR Code", true);
// You can also save it to disk by uncommenting the line below
// UtilImageIO.saveImage(image,"qrcode.png");
// WARNING! This rendered image lacks the white border which is required to be a compliant
// QR Code. As of this writing BoofCV's implementation might not be able to handle
// this image unless you add a white border.
