Namespace:
Microsoft.UI.Xaml.Controls
Edit

An animated Visual that can be used by other objects, such as an AnimatedIcon.

This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).

Examples

This example displays and animates an object that implements IAnimatedVisualSource2:

void AddVisualAndShowStartAnimation(
    const winrt::Border& element,
    const& winrt::IAnimatedVisualSource2 source,
    const winrt::hstring& initialState,
    const winrt::hstring& steadyState,
    const winrt::Color& themeColor )
{
    winrt::IAnimatedVisual animatedVisual = source.TryCreateAnimatedIconVisual();

    // Find the playback positions in the animation of the two states
    auto const markers = source.Markers();
    auto const fromProgress = static_cast<float>(markers.Lookup(initialState));
    auto const toProgress = static_cast<float>(markers.Lookup(steadyState));

    // Set the theme color as the animated visual's foreground.
    source.SetColorProperty("Foreground", themeColor);

    // Helper that uses TryCreateAnimatedVisual to add the source to the XAML element tree.
    // See IAnimatedVisualSource.TryCreateAnimatedVisual for more information.
    AddVisualToElement(element, animatedVisual);

    // Helper to play an animation.
    // See IAnimatedVisual for more information.
    PlaySegment(animatedVisual.RootVisual(), fromProgress, toProgress);
}

Remarks

Call the IAnimatedVisualSource.TryCreateAnimatedVisual method to retrieve an IAnimatedVisual object. This IAnimatedVisual can then be used to get a Composition.Visual, which can be added to a XAML element tree using the methods of ElementCompositionPreview.

Properties

Markers

Gets a collection that provides a mapping of marker names to playback positions in the animation.
