> org.apache.pdfbox.pdmodel.interactive.viewerpreferences.PDViewerPreferences
> currently doesn't support viewer preferences Duplex and PrintScaling (defined
> in PDF Reference 1.7, Table 8.1). I created a simple patch to the above
> mentioned class including the two preferences.
> Notes:
> 1. They require pdfversion 1.7 and 1.6 respectively. I don't know if this is
> the reason why they are not currently available and I also don't know if
> there's a way in PDFBox to make sure that the document version is consistent
> with the version required by the preferences.
> 2. Since the target jdk version is 1.5 I suggest to refactor the viewer
> preferences area to use Enums instead of String constants (Ex. right now I
> think nothing prevents to set a READING_DIRECTION constant as a
> NON_FULL_SCREEN_MODE) making the code more robust.
