Description

This PDF Creation Listener parses meta data elements from an (X)HTML document and appends them to the info dictionary of a PDF document.

The XHTML document is parsed for relevant PDF meta data during construction, then adds the meta data to the PDF document when the PDF document is closed by the calling ITextRenderer.

• SUBJECT, DC.SUBJECT
• KEYWORDS

Valid PDF meta names are defined in Adobe's PDF Reference (Sixth Edition), section "10.2.1 - Document Information Dictionary", table 10.2, pg.844 http://www.adobe.com/devnet/pdf/pdf_reference.html

Usage

 // Setup output stream
 OutputStream outputStream = ... 
 
 // Create W3C document model
 Document doc = ...
 
 // Create new PDF renderer
 ITextRenderer renderer = new ITextRenderer();
 
 // Add PDF creation listener
 PDFCreationListener pdfCreationListener = new XHtmlMetaToPdfInfoAdapter( doc );
 renderer.setListener( pdfCreationListener);
 
 // Add W3C document to renderer
 renderer.setDocument( doc, null );
       
 // Layout PDF document
 renderer.layout();
 
 // Write PDF document
 renderer.createPDF( outputStream, true );
