docs: This is the most simple way to change a PDF into a
  portable collection. Choose one of the following names:
  <ul>
  <li>PdfName.D (detailed view)
  <li>PdfName.T (tiled view)
  <li>PdfName.H (hidden)
  </ul>
  Pass this name as a parameter and your PDF will be
  a portable collection with all the embedded and
  attached files as entries.
  @param initialView can be PdfName.D, PdfName.T or PdfName.H
