Change the zoom level of a document

The DocViewerApp provides several methods to set the zoom level of a document page shown in preview mode or a running ViewApp. A page can be zoomed out to a minimum of nine percent of its original size and zoomed in to a maximum of 500 percent.

• Zoom in and zoom out controls

  

  These controls appear above the displayed document on the menu bar. Each time the user selects a zoom in or zoom out control, the view magnification increases or decreases by ten percent.

• Zoom slider control

  

  The slider control appears beneath the displayed document on the status bar. Moving the slider right or left increases or decreases the magnification of the document view.

  Users can also select the + or - controls at the ends of the slider. Each press of the + control increments magnification of a document by10 percent. Each press of the - control decrements magnification of a document by 10 percent.
