# SetDisplayMode

`SetDisplayMode(mixed zoom [, string layout])`

## Description

Defines the way the document is to be displayed by the viewer. The zoom level can be set: pages can be displayed entirely on screen, occupy the full width of the window, use real size, be scaled by a specific zooming factor or use viewer default (configured in the Preferences menu of Acrobat). The page layout can be specified too: single at once, continuous display, two columns or viewer default.
By default, documents use the full width mode with continuous display.

## Parameters

  or a number indicating the zooming factor to use.
`layout`
  The page layout. Possible values are:
