title: Create an Image or PdfTemplate from a PDF file
body: <p>While using the itextsharp library for pdf generation, I came across this method:-</p>
  
  <pre><code>iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(itextsharp.text.pdf.PdfTemplate);
  </code></pre>
  
  <p>Where, we can get Image instance from a PdfTemplate. But, I don't know how to create a PdfTemplate and there is no constructor taking a pdf file name or stream.</p>
  
  <p>Why I want this is: I want to create an Image from a PDF file and then isert this image into another pdf file.</p>
  
  <p>Anybody knows how to create PdfTemplate object ?</p>
