Save PDF with Bookmarks

How to save a book as PDF with bookmarks?

I am exporting an open book as PDF using the following script:

var params = GetSaveDefaultParams()

var returnParamsp =new PropVals()

var i = GetPropIndex(params, Constants.FS_FileType)

params[i].propVal.ival =Constants.FV_SaveFmtPdf

file.Save(pdfName, params, returnParamsp)

This works fine but the pdf document does not have bookmarks. I would like to get the same

result as if a selected "Generate PDF bookmarks" (translated from German) on the Bookmars

page of the PDF Settings dialog.

I guess I will have to set some property value, but which one? Is there a place where I can

look it up?

Thanks
