        JLabel label = new JLabel("ABCD");
        label.setSize(label.getPreferredSize());
        label.putClientProperty(KEY_TEXT_ANTIALIASING, aaHint);
        label.putClientProperty(KEY_TEXT_LCD_CONTRAST, lcdContrast);

        int w = label.getWidth();
        int h = label.getHeight();

        BufferedImage buffImage = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);
        Graphics2D g = buffImage.createGraphics();
        g.setColor(Color.WHITE);
        g.fillRect(0, 0, w, h);
        label.paint(g);
        g.dispose();

        HashSet<Color> colors = new HashSet<>();
