title: What is BufferedImageOp stands for?
body: <p>I just want to enlarge a <code>BufferedImage</code> and make a watermark on it.Here is my code.</p>
  
  <pre><code>            BufferedImage image = GetHtmlImage(doc, base_url, width, -1);
              if (image.getHeight() &lt; MaxShortHeight) {
                  return "";
              }
              BufferedImage gimage = new BufferedImage(image.getWidth(), image.getHeight() + 20, BufferedImage.TYPE_INT_RGB);
              Graphics2D g2 = gimage.createGraphics();
              g2.setBackground(Color.WHITE);
              g2.drawImage(image, BufferedImageOp, 0, 0);
              g2.setColor(Color.BLACK);
              g2.drawString("Press by Shisoft WebFusion http://www.shisoft.net/", 10, image.getHeight() - 10);
              ByteArrayOutputStream os = new ByteArrayOutputStream();
              ImageIO.write(gimage, "jpeg", os);
  </code></pre>
  
  <p>At 'g2.drawImage(image, BufferedImageOp, 0, 0);'.I don't know what is <code>BufferedImageOp</code>.Could someone make an example.</p>
  
  <p>Thank you.</p>
