// 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;
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
Remarks
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.
