<div class="markdown level1 remarks"><p>Most long Pdf documents contain an outline structure that is displayed on a pane
on the left of the reader. The outline makes it easy to browse through a
document's structure and find specific topics. The <b>AddBookmark</b>
method allows you to build this outline structure by adding outline entries
(bookmarks).</p>
