What is the difference between iText's getPageN() and getPageNRelease() calls?
<p>I've wondered this for awhile.  There are two calls in PdfReader for getting a page dictionary:  getPageN() and getPageNRelease().</p>

<p>Under which circumstances should we use one or the other?  </p>

<p>Are there performance implications of one or the other?</p>

<p>For example, I have an algorithm that is iterating each page in an existing PDF and reading data from it.  Which call should I use?</p>
