title: Taking screenshot of a webpage programmatically
body: <p>How do take a sceenshot of a webpage programmatically given the URL as input?</p>
  
  <p>And here is what I have till now:</p>
  
  <pre><code>// The size of the browser window when we want to take the screenshot (and the size of the resulting bitmap)
  Bitmap bitmap = new Bitmap(1024, 768);
  Rectangle bitmapRect = new Rectangle(0, 0, 1024, 768);
  // This is a method of the WebBrowser control, and the most important part
  webBrowser1.DrawToBitmap(bitmap, bitmapRect);
  
  // Generate a thumbnail of the screenshot (optional)
  System.Drawing.Image origImage = bitmap;
  System.Drawing.Image origThumbnail = new Bitmap(120, 90, origImage.PixelFormat);
  
  Graphics oGraphic = Graphics.FromImage(origThumbnail);
  oGraphic.CompositingQuality = CompositingQuality.HighQuality;
  oGraphic.SmoothingMode = SmoothingMode.HighQuality;
  oGraphic.InterpolationMode = InterpolationMode.HighQualityBicubic;
  Rectangle oRectangle = new Rectangle(0, 0, 120, 90);
  oGraphic.DrawImage(origImage, oRectangle);
  
  // Save the file in PNG format
  origThumbnail.Save(@"d:\Screenshot.png", ImageFormat.Png);
  origImage.Dispose();
  </code></pre>
  
  <p>But this is not working. It is only giving me a white blank picture. What am I missing here?</p>
  
  <p>Is there any other way I could get the screenshot of a web page programmatically?</p>
