ScaleFactor Property (RasterImageViewer)

Summary

The zoom factor used to display the image.

Syntax

C++

[DescriptionAttribute("Select one of the center mode available to the control (none, horizontal, vertical or both).")] 
[CategoryAttribute("Behavior")] 
public virtual double ScaleFactor {get; set;}

<DescriptionAttribute("Select one of the center mode available to the control (none, horizontal, vertical or both).")> 
<CategoryAttribute("Behavior")> 
Public Overridable Property ScaleFactor As Double

[DescriptionAttribute("Select one of the center mode available to the control (none, horizontal, vertical or both).")] 
[CategoryAttribute("Behavior")] 
public: 
virtual property double ScaleFactor { 
   double get(); 
   void set (    double ); 
}

Property Value

The zoom factor used to display the image.

Remarks

You can get and set this property when the SizeMode property is RasterPaintSizeMode.Normal. This property is read only when the SizeMode property is set to any other value. When SizeMode is set to RasterPaintSizeMode.Stretch, the zoom factor is the smallest of the Width or Height zoom factors (the aspect ratio is not preserved).

Public Sub RasterImageViewer_ScaleFactor(ByVal viewer As RasterImageViewer) 
   viewer.ScaleFactor = viewer.ScaleFactor * 0.9F 
   Dim s As String = String.Format("CurrentXScaleFactor {0}, CurrentYScaleFactor {1}", viewer.CurrentXScaleFactor, viewer.CurrentYScaleFactor) 
   MessageBox.Show(s) 
End Sub
