JLabelのテキストで背景画像を切り抜いて表示する

JLabel label = new JLabel("ABC") {
  @Override protected void paintComponent(Graphics g) {
    // super.paintComponent(g);
    Graphics2D g2 = (Graphics2D) g.create();
    g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                        RenderingHints.VALUE_ANTIALIAS_ON);
    g2.drawImage(image, 0, 0, getWidth(), getHeight(), this);
    FontRenderContext frc = g2.getFontRenderContext();
    String text = getText();
    GlyphVector gv = getFont().createGlyphVector(frc, text);
    Rectangle2D b = gv.getVisualBounds();
    double w = getWidth();
    double h = getHeight();
    double cx = w / 2d - b.getCenterX();
    double cy = h / 2d - b.getCenterY();
    AffineTransform toCenter = AffineTransform.getTranslateInstance(cx, cy);
    Shape s = toCenter.createTransformedShape(gv.getOutline());
    Area bg = new Area(new Rectangle2D.Double(0d, 0d, w, h));
    bg.subtract(new Area(s));
    g2.setColor(getBackground());
    g2.fill(bg);
    g2.dispose();
  }
};
label.setBackground(new Color(0xE6_00_00_32, true));
label.setFont(new Font(Font.SERIF, Font.BOLD, 140));
