Expand description

PDF viewer-preference hints, gathered from the catalog’s /ViewerPreferences sub-dict plus the catalog-level /PageLayout and /PageMode.

Every field has a spec-defined default (see ISO 32000-2 §12.2 Table 147, §7.7.2 Table 28); a document with no /ViewerPreferences dict gets all defaults.

Fields§

§hide_toolbar: bool

/HideToolbar — hide viewer toolbar when document is active.

§hide_menubar: bool

/HideMenubar — hide viewer menu bar.

§hide_window_ui: bool

/HideWindowUI — hide UI elements like scroll bars.

§fit_window: bool

/FitWindow — resize the window to fit the first page.

§center_window: bool

/CenterWindow — center the window on the screen.

§display_doc_title: bool

/DisplayDocTitle — display the document title in the title bar.

§non_full_screen_page_mode: PageMode

/NonFullScreenPageMode — /PageMode to use when leaving full-screen.

§direction: ReadingDirection

/Direction — predominant reading order.

§page_layout: PageLayout

Catalog-level /PageLayout.

§page_mode: PageMode

Catalog-level /PageMode.

§print_scaling: PrintScaling

/PrintScaling — default print-scaling preference.

§duplex: Option<Duplex>

/Duplex — default print-duplex preference.

§pick_tray_by_pdf_size: Option<bool>

/PickTrayByPDFSize — choose paper tray based on PDF page size.

§num_copies: Option<u32>

/NumCopies — default number of copies to print.
