7 printed
8
10 This has been split out from preferences() in PDF::Builder.

13 Creates a new ViewerPreferences object from a PDF::Builder object.
14 %preferences = $self->get_preferences()
16 Returns a hash containing all of the viewer preferences that are

21 "undef" if not.

24 Sets one or more viewer preferences, as described in the
25 preferences section below.

28 Viewer Preferences describe how the document should be presented on
29 screen or in print. Not all PDF viewers will respect these
30 preferences.
31 Boolean preferences default to false and take (or return) 0 or 1 as
33 arguments.
34 Bounding Box preferences take (or return) one of "media_box",
36 "crop_box", "bleed_box", "trim_box", or "art_box".

63 display the name of the PDF file containing the document.
64 non_full_screen_page_mode (name)
66 The document's page mode, specifying how to display the document on
67 exiting full-screen mode. Options are the same as "page_mode" in

69 options aren't supported.
70 direction ('l2r' or 'r2l')
72 The predominant reading order for text (left-to-right or right-to-
73 left).
74 This entry has no direct effect on the document's contents or page

99 duplex ('simplex', 'duplex_short', or 'duplex_long')
101 The paper handling option that shall be used when printing the file
102 from the print dialog. The duplex values represent whether the
103 page should be flipped on its short edge or long edge,
104 respectively.
105 pick_tray_by_pdf_size (boolean)
107 A flag specifying whether the PDF page size shall be used to select

112 The page numbers used to initialize the print dialog box when the
113 file is printed. The array shall contain an even number of
114 integers to be interpreted in pairs, with each pair specifying the
