    int height = originalImage.getHeight();
    final BufferedImage textImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g = textImage.createGraphics();

    FontRenderContext frc = g.getFontRenderContext();
    Font font = new Font("Arial", Font.BOLD, 50);
    GlyphVector gv = font.createGlyphVector(frc, "java2s.com");

    int xOff = 0;
    int yOff = 50;

    Shape shape = gv.getOutline(xOff, yOff);
