為什麼我的文字疊加不能正確顯示在 BufferedImage 上？

gO.drawString(this.text, this.x, this.y + 12);

private BufferedImage process(BufferedImage image) {
    Graphics2D g2d = image.createGraphics();
    // Code to overlay text...
    g2d.dispose();
    return image;
}

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 + 12);
    System.err.println(this.text+this.x+this.y);
    return image;
}
