CircularTransition Class

Summary

The CircularTransition class gives you precise control over Circular transition effects.

Syntax

C++

public class CircularTransition : Leadtools.Windows.Media.Transitions.EllipticalTransition, System.Windows.Media.Animation.IAnimatable

Public Class CircularTransition  
   Inherits Leadtools.Windows.Media.Transitions.EllipticalTransition 
   Implements System.Windows.Media.Animation.IAnimatable

public ref class CircularTransition : public Leadtools.Windows.Media.Transitions.EllipticalTransition, System.Windows.Media.Animation.IAnimatable

Example

This example will create a CircularTransition 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 CircularTransition_CircularTransition(ByVal viewer As ImageViewer) 
   Dim circularTransition As CircularTransition = New CircularTransition() 
   circularTransition.TransitionType = EllipticalTransitionType.CenterInterlaceInOut 
   circularTransition.AutoReverse = True 
   circularTransition.Fill = New ImageBrush(New BitmapImage(New Uri(System.IO.Path.Combine(LEAD_VARS.ImagesDir, "sample3.cmp")))) 
   circularTransition.Duration = New Duration(TimeSpan.FromSeconds(1)) 
   circularTransition.FillBehavior = System.Windows.Media.Animation.FillBehavior.HoldEnd 
   circularTransition.Grain = 10 
 
   viewer.Transition = circularTransition 
 
   ' Begin the transition 
   circularTransition.Begin() 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
