FO Processor Tab (DITA OT Transformations)

When you create a new transformation scenario or edit an existing one, a configuration dialog box allows you to customize the transformation with various options in several tabs.

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

• 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 DITA_OT_DIR/plugins/org.dita.pdf2/lib directory of the Oxygen XML Author plugin installation directory.
