XSL-FO (Apache FOP) Processor for Generating PDF Output

The Oxygen XML Author installation package is distributed with the Apache FOP that is a Formatting Objects processor for transforming your XML documents to PDF. FOP is a print and output independent formatter driven by XSL Formatting Objects. FOP is implemented as a Java application that reads a formatting object tree and renders the resulting pages to a specified output.

To see the version of the built-in XSL-FO processor for your installation, go to Help > About > Libraries and search for Apache FOP.

Other FO processors can be configured in the FO Processors preferences page.
