title: ITextSharp Multiple Page PDF from several templates
body: <p>I have a requirement to generate a PDF from multiple different (Unknown page Sized PDF's)</p>
  
  <ol>
  <li>Create a cover sheet from a template and write the text onto it.</li>
  <li>Pull a PDF (Unknown page size) and append to the above 3) Repeat</li>
  <li>until all required PDF's are attached</li>
  </ol>
  
  <p>Step 1 is not a problem and this is working, so I have a a cover sheet PDF generated. I now need a way to append the additional PDF's as above. How can we achieve this using ITextSharp?</p>
