Example

This example will create a ZoomTransition and apply it to a Leadtools.Windows.Controls.ImageViewer control.

Imports Leadtools.Windows.Media.Transitions 
Imports LeadtoolsWpfTransitionsExamples.Leadtools.Help 
Imports Leadtools.Windows.Controls 
 
Public Sub ZoomTransition_ZoomTransition(ByVal viewer As ImageViewer) 
   Dim zoomTransition As ZoomTransition = New ZoomTransition() 
   zoomTransition.TransitionType = ZoomTransitionType.FromCenter 
   zoomTransition.AutoReverse = True 
   zoomTransition.Fill = New ImageBrush(New BitmapImage(New Uri(System.IO.Path.Combine(LEAD_VARS.ImagesDir, "sample3.cmp")))) 
   zoomTransition.Duration = New Duration(TimeSpan.FromSeconds(1)) 
   zoomTransition.FillBehavior = System.Windows.Media.Animation.FillBehavior.HoldEnd 
   zoomTransition.Grain = 10 
 
   viewer.Transition = zoomTransition 
 
   ' Begin the transition 
   zoomTransition.Begin() 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
