Examples

The following example shows how to use IncreaseZoom in conjunction with a FlowDocumentPageViewer. The FlowDocumentPageViewer provides an implementation that responds to the IncreaseZoom command by decreasing the zoom percentage.

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">

<!-- NavigationCommands.IncreaseZoom -->
<MenuItem
  Command="NavigationCommands.IncreaseZoom"
  CommandTarget="{Binding ElementName=flowDocumentPageViewer}" />

<!-- The following FlowDocumentPageViewer is used to process NavigationCommands.IncreaseZoom commands -->
<FlowDocumentPageViewer Name="flowDocumentPageViewer">
  <FlowDocument>

Remarks

This command indicates the intention to increase the zoom.

DocumentViewer, FlowDocumentReader, FlowDocumentScrollViewer, and FlowDocumentPageViewer implement support for responding to the IncreaseZoom command, although you are not required to use it; in many cases the implementation in response to that command is the responsibility of the application writer.
