GenerateImage.java

private BufferedImage generateImage(MobileElement element, File screenshot) {
    BufferedImage qrCodeImage = null;

    try {
        BufferedImage fullImage = ImageIO.read(screenshot);
        Point imageLocation = element.getLocation();

        int qrCodeImageWidth = element.getSize().getWidth();
        int qrCodeImageHeight = element.getSize().getHeight();

        int pointXPosition = imageLocation.getX();
        int pointYPosition = imageLocation.getY();

        qrCodeImage = fullImage.getSubimage(pointXPosition, pointYPosition, qrCodeImageWidth, qrCodeImageHeight);
        ImageIO.write(qrCodeImage, "png", screenshot);
    } catch (IOException e) {
        log.error("Problem during the image generation", e);
