FO Processor Tab (DITA-OT Transformations)
The FO Processor tab is available for DITA-OT transformations with a PDF output type.
This tab allows you to select an FO Processor to be used for the transformation.


You can choose one of the following processors:
- Apache FOP
- The default processor that comes bundled with Oxygen XML.
- XEP
- The RenderX
XEP processor. If XEP is already installed, Oxygen XML displays the detected
installation path under the drop-down menu. XEP is considered installed if it was
detected in one of the following sources:
- XEP was configured as an external FO Processor in the FO Processors option page.
- The system property com.oxygenxml.xep.location was set to point to the XEP executable file for the platform (for example: xep.bat on Windows).
- XEP was installed in the /plugins/org.dita.pdf2/lib directory of the Oxygen XML installation directory.
- Antenna House
-
The Antenna House (AH Formatter) processor. If Antenna House is already installed, Oxygen XML displays the detected installation path under the drop-down menu. Antenna House is considered installed if it was detected in one of the following sources:
- Environment variable set by Antenna House installation (the newest installation version will be used).
- Antenna House was added as an external FO Processor in the Oxygen XML preferences pages.
To further customize the PDF output obtained from the Antenna House processor, follow these steps:- Edit the transformation scenario.
