Struct ViewerPreferences

pub struct ViewerPreferences<'a> { /* private fields */ }

Writer for a viewer preference dictionary.

This struct is created by Catalog::viewer_preferences.

Implementations

impl ViewerPreferences<'_>

pub fn hide_toolbar(&mut self, hide: bool) -> &mut Self

Write the /HideToolbar attribute to set whether the viewer should hide its toolbars while the document is open.

pub fn hide_menubar(&mut self, hide: bool) -> &mut Self

Write the /HideMenubar attribute to set whether the viewer should hide its menu bar while the document is open.

pub fn fit_window(&mut self, fit: bool) -> &mut Self

Write the /FitWindow attribute to set whether the viewer should resize its window to the size of the first page.

pub fn center_window(&mut self, center: bool) -> &mut Self

Write the /CenterWindow attribute to set whether the viewer should center its window on the screen.

pub fn display_doc_title(&mut self, display: bool) -> &mut Self

Write the /DisplayDocTitle attribute to set whether the viewer should display the document’s title from the Title entry as the window’s title. PDF 1.4+

pub fn non_full_screen_page_mode(&mut self, mode: PageMode) -> &mut Self

Write the /NonFullScreenPageMode attribute to set which chrome elements the viewer should show for a document which requests full screen rendering in its catalog when it is not shown in full screen mode.

Panics if mode is PageMode::FullScreen.

pub fn direction(&mut self, dir: Direction) -> &mut Self

Write the /Direction attribute to aid the viewer in how to lay out the pages visually. PDF 1.3+.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.
