The RtfWriter is in bug-fix-only mode, * will be deprecated end of 2005 and removed end of 2007. * * A DocWriter class for Rich Text Files (RTF). *

* A RtfWriter can be added as a DocListener * to a certain Document by getting an instance. * Every Element added to the original Document * will be written to the OutputStream of this RtfWriter. *

* Example: *

 * // creation of the document with a certain size and certain margins
 * Document document = new Document(PageSize.A4, 50, 50, 50, 50);
 * try {
 *    // this will write RTF to the Standard OutputStream
 *    RtfWriter.getInstance(document, System.out);
 *    // this will write Rtf to a file called text.rtf
 *    RtfWriter.getInstance(document, new FileOutputStream("text.rtf"));
 *    // this will write Rtf to for instance the OutputStream of a HttpServletResponse-object
 *    RtfWriter.getInstance(document, response.getOutputStream());
 * }
 * catch(DocumentException de) {
 *    System.err.println(de.getMessage());
 * }
 * // this will close the document and all the OutputStreams listening to it
 * document.close();
 * 
*

* LIMITATIONS
* There are currently still a few limitations on what the RTF Writer can do: *
