Example

This C#/VB.NET code shows how to show animation from GIF image file in WpfAnimatedImageViewer.

VB.NET


''' <summary>
''' Shows animation in animated image viewer.
''' </summary>
''' <param name="viewer">An animated image viewer.</param>
''' <param name="filename">The filename.</param>
Private Sub StartAnimation(viewer As Vintasoft.Imaging.Wpf.UI.WpfAnimatedImageViewer, filename As String)
    ' if image collection of the image viewer is not empty
    If viewer.Images.Count > 0 Then
        ' clear the image collection of the image viewer
        viewer.Images.ClearAndDisposeItems()
    End If
    ' open the file
    viewer.Images.Add(filename)
    ' start the animation
    viewer.Animation = True
End Sub


/// <summary>
/// Shows animation in animated image viewer.
/// </summary>
/// <param name="viewer">An animated image viewer.</param>
/// <param name="filename">The filename.</param>
private void StartAnimation(Vintasoft.Imaging.Wpf.UI.WpfAnimatedImageViewer viewer, string filename)
{
    // if image collection of the image viewer is not empty
    if (viewer.Images.Count > 0)
    {
        // clear the image collection of the image viewer
        viewer.Images.ClearAndDisposeItems();
    }
    // open the file
    viewer.Images.Add(filename);
    // start the animation
    viewer.Animation = true;
