How can I export a pdf with 'edit=>changes=>show' disabled?

I can load LibreOffice 4.0 with python uno bridge ok, and load a document with writer and save it out to pdf.

Using python uno, I want to disable toolbar=>edit=>changes=>show before saving to a local file URL as a pdf. If I don’t do this, the exported pdf shows up with strike-out text from previous edits visible.

What is the nodepath to this option, and what ParameterValue should I set it to?

The name of change tracking aspects is “Redline”. Node path is com.sun.star.document.RedlineDisplayType and the parameter values are given here. Presumably you want NONE.
