Change the zoom level of a spreadsheet

The SpreadsheetViewerApp provides several methods to set the zoom level of the worksheet shown in preview mode or a running ViewApp. A worksheet can be zoomed out to a minimum of ten percent of its original size or zoomed in to a maximum of 400% using the slider magnification tool, or to an infinite percentage using the zoom control magnifier icon.

• 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 15 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 + or - control increases or decreases magnification in increments of 10 percent.
