The following example shows how to set the Zoom attribute.

<FlowDocumentScrollViewer
  HorizontalScrollBarVisibility="Auto" 
  VerticalScrollBarVisibility="Auto" 
  IsSelectionEnabled="True" 
  IsToolBarVisible="True" 
  MinZoom="50" MaxZoom="1000"
  Zoom="120" ZoomIncrement="5"
>
  <FlowDocument>
    <Paragraph>
      Flow content...
    </Paragraph>
  </FlowDocument>
</FlowDocumentScrollViewer>

The following example shows how to set the Zoom property programmatically.

FlowDocumentScrollViewer flowDocScrollViewer = new FlowDocumentScrollViewer();

// Enable content selection.
flowDocScrollViewer.IsSelectionEnabled = true;
// Enable the toolbar.
flowDocScrollViewer.IsToolBarVisible = true;

// Set zoom between 50% and 1000%.
flowDocScrollViewer.MinZoom = 50;
flowDocScrollViewer.MaxZoom = 1000;
// Set the zoom increment to 5%.
flowDocScrollViewer.ZoomIncrement = 5;
// Set the initial zoom to 120%.
flowDocScrollViewer.Zoom = 120;

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("Flow content...")));
flowDocScrollViewer.Document = flowDoc;
