Bagaimana untuk Menghamparkan Teks dengan betul pada BufferedImage menggunakan Graphics2D?

protected BufferedImage Process2(BufferedImage image){
    Graphics2D gO = image.createGraphics();
    gO.setColor(Color.red);
    gO.setFont(new Font( "SansSerif", Font.BOLD, 12 ));
    gO.drawString(this.text, this.x, this.y);
    System.err.println(this.text+this.x+this.y);
    return image;
}

public class TextOverlay {

    public static BufferedImage process(BufferedImage image, String text, int x, int y) {
        int w = image.getWidth();
        int h = image.getHeight();
        BufferedImage processed = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);

        // Create Graphics2D object for the processed image
        Graphics2D g2 = processed.createGraphics();

        // Transfer the contents of the original image to the processed image
        g2.drawImage(image, 0, 0, w, h, null);

        // Set the text color and font
        g2.setColor(Color.red);
        Font font = new Font("SansSerif", Font.BOLD, 12);
        g2.setFont(font);

        // Get the font metrics to determine the bounding box for the text
        FontMetrics fm = g2.getFontMetrics(font);
        int textWidth = fm.stringWidth(text);
        int textHeight = fm.getAscent() - fm.getDescent();

        int textX = x - textWidth / 2;

        // Draw the text on the processed image
        g2.drawString(text, textX, textY);

        // Dispose of the Graphics2D object
        g2.dispose();

BufferedImage image = ... // Load your original image

String text = "Hello, world!";

// Use the processed image as needed
