Description

This script allows to set some viewer preferences.

DisplayPreferences(string preferences)

The available settings are (case-sensitive):

FullScreen: displays the document full-screen
HideMenubar: hides the menu
HideToolbar: hides all toolbars
HideWindowUI: hides all window elements (scrollbars, navigation controls, bookmarks...)
DisplayDocTitle: displays the title of the document instead of the file name
CenterWindow: centers the window
FitWindow: sizes the window (when not maximized) to fit the page

Note: these settings are ignored when the PDF is displayed in a browser.
