The PDFSettings property returns a PDFVBASettings object that allows you to set options used when publishing to PDF.
Examples:
The following VBA example publishes the current document to PDF with some of the settings changed from their defaults.
Sub Test()
With ActiveDocument.PDFSettings
.Author = "John Doe"
.ColorMode = pdfCMYK
.ComplexFillsAsBitmaps = True
.FountainSteps = 10
End With
ActiveDocument.PublishToPDF "C:\Temp\Document.pdf"
End Sub
