Usage

From source file:Main.java

public static void main(String[] args) {
    String s = "The quick brown fox jumps over the lazy dog!";
    BufferedImage bi = new BufferedImage(1, 1, BufferedImage.TYPE_INT_RGB);
    Graphics g = bi.getGraphics();
    FontMetrics fm = g.getFontMetrics();
    Rectangle2D b = fm.getStringBounds(s, g);
    System.out.println(b);/*from   w  w  w .  j a va2s .  c o  m*/
    bi = new BufferedImage((int) b.getWidth(), (int) (b.getHeight() + fm.getDescent()),
            BufferedImage.TYPE_INT_RGB);
    g = bi.getGraphics();
    g.drawString(s, 0, (int) b.getHeight());

    JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(bi)));

    // Technique 3 - JLabel
    JLabel l = new JLabel(s);
    l.setSize(l.getPreferredSize());
    bi = new BufferedImage(l.getWidth(), l.getHeight(), BufferedImage.TYPE_INT_RGB);
    g = bi.getGraphics();
    g.setColor(Color.WHITE);
    g.fillRect(0, 0, 400, 100);
    l.paint(g);

    JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(bi)));
