Module viewer_prefs 

PDF viewer preferences from the catalog’s /ViewerPreferences dict (and the catalog-level /PageLayout and /PageMode entries that travel with them).

These preferences are hints PDF viewers should honor when displaying the document — whether to hide chrome, fit the window to the first page, which page mode to open in, etc. They are advisory, not mandatory; consumers may override.
