How to remove document structure tags by default?

[hana]

I want to export Visio documents as PDFs but don't want the document structure tags on.  I know I can uncheck the box each time I wish to convert the document, but is there a way of making this the default?
I'm also curious why would you want a black outline around an image like that?

In Visio you can export document to PDF/XPS format via code with ExportAsFixedFormat method. This method have parameters: ColorAsBlack, IncludeBackground and IncludeStructureTags. Each of these parameters have default value, which is TRUE.
You can write simple one line macro like as in the example for change these parameters...
