FlowDocumentReader.MinZoom Property

Definition

Gets or sets the minimum allowable Zoom level for the FlowDocumentReader.

C#
public double MinZoom { get; set; }

Property Value

The minimum allowable Zoom level for the FlowDocumentReader, interpreted as a percentage. The default is 80.0 (minimum zoom of 80%).

Examples

The following example shows how to set the MinZoom attribute.

XAML
<FlowDocumentReader
  IsFindEnabled="True"  
  IsPrintEnabled="True"
  MinZoom="50" MaxZoom="1000"
  Zoom="120" ZoomIncrement="5"
>
  <FlowDocument>
    <Paragraph>
      Flow content...
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

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

C#
FlowDocumentReader flowDocRdr = new FlowDocumentReader();

// Enable find...
flowDocRdr.IsFindEnabled = true;
// Enable printing...
flowDocRdr.IsPrintEnabled = true;
// Set zoom between 50% and 1000%.
flowDocRdr.MinZoom = 50;
flowDocRdr.MaxZoom = 1000;
// Set the zoom increment to 5%.
flowDocRdr.ZoomIncrement = 5;
// Set the initial zoom to 120%.
flowDocRdr.Zoom = 120;

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

Remarks

The default FlowDocumentReader user interface (UI) includes a slider that can be used to adjust the Zoom level. This property specifies the lower-limit value for the Zoom slider.
