<question>What tools are available for post-processing my PDF document?</question>
<answer>
- <ul>
- <li>
- The most popular one that we are aware of is <link
- href="http://www.lowagie.com/iText">iText</link>, which has tools
- for adding security features, document properties, watermarks, and
- many other features to PDF files. FOP and iText can be integrated
- into one Java application, see sample code for <link
- href="#pdf-security">encryption</link>.
- The bad news is that iText swallows PDF bookmarks.
- </li>
-
- <li>
- You can use Adobe Acrobat (the full version, not the Reader) to
- process the file manually or with scripting that it supports.

PDF is the best supported output format. It is also the most accurate
with text and layout. This creates a PDF document that is streamed out
as each page is rendered. This means that the internal page index
