Oxygen XML Editor includes a built-in DITA Map PDF - based on HTML5 & CSS transformation scenario based on a DITA-OT CSS-based PDF Publishing plugin that converts DITA maps to PDF using a CSS-based processing engine and an HTML5 intermediate format. Oxygen XML Editor comes bundled with a built-in CSS-based PDF processing engine called Oxygen PDF Chemistry. Oxygen XML Editor also supports some third-party processors.

For those who are familiar with CSS, this makes it very easy to style and customize the PDF output of your DITA projects without having to work with xsl:fo customizations. This transformation also includes some built-in publishing templates that you can use for the layout of your PDF output and you can create your own templates or edit existing ones.

The following CSS-based PDF processors can be used:
  • Oxygen PDF Chemistry - A built-in processor that is bundled with Oxygen XML Editor. For more information, see the Oxygen PDF Chemistry User Guide. This is the supported processor.
  • Prince Print with CSS (not included in the Oxygen XML Editor installation kit) - A third-party component that needs to be purchased from http://www.princexml.com.
  • Antenna House Formatter (not included in the Oxygen XML Editor installation kit) - A third-party component that needs to be purchased from http://www.antennahouse.com/antenna1/formatter/.
