  <p>please click on the link and see what value i should provide to extract left rectangle. can you give me any idea.</p>
  
  <p>i got code to crop a portion of image. here is one sample for cropping programmatically.</p>
  
  <pre><code>Rectangle cropRect = new Rectangle(...);
  Bitmap src = Image.FromFile(fileName) as Bitmap;
  Bitmap target = new Bitmap(cropRect.Width, cropRect.Height);
  
  using(Graphics g = Graphics.FromImage(target))
  {
      g.DrawImage(src, new Rectangle(0, 0, target.Width, target.Height), 
                  cropRect,                        
                  GraphicsUnit.Pixel);
  }
  </code></pre>
  
  <p>my concern is what value i should give here to crop the exact left rectangle from the image. <code>Rectangle cropRect = new Rectangle(...);</code></p>
  
  <p>can anyone give me any idea. thanks i got this code from this url
