Add Duplex and PrintScaling to viewer preferences
-------------------------------------------------
Key: PDFBOX-1111
URL: https://issues.apache.org/jira/browse/PDFBOX-1111
Project: PDFBox
Issue Type: Improvement
Components: PDModel
Affects Versions: 1.6.0
Environment: Patch created on version 1.7.0-SNAPSHOT, Revision 1163182.
Reporter: Andrea Vacondio
Priority: Minor
Fix For: 1.7.0
Attachments: duplex_and_printscaling.diff
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.
