<object Zoom="double" .../>
Property Value
Type: System.DoubleThe current zoom level, interpreted as a percentage. The default value 100.0 (zoom level of 100%).
Default FlowDocumentReader user interface (UI) includes a zoom control that provides buttons for increasing or decreasing the zoom, as well as a slider for adjusting the zoom level. The following figure shows the zoom controls on a FlowDocumentReader with default UI.

The zoom level is constrained by the values of the MinZoom and MaxZoom properties.
The following example shows how to set the Zoom attribute.
<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 Zoom property programmatically.
Dim flowDocRdr As 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 Dim flowDoc As New FlowDocument(New Paragraph(New Run("Flow content..."))) flowDocRdr.Document = flowDoc
