AnimatedImage

A simple library to display animated GIF images , animated PNG images and animated WEBP images in WPF and AvaloniaUI, usable in XAML or in code.

How to use (WPF)

These properties are compatible with those of WpfAnimatedGif.

It's very easy to use: in XAML, instead of setting the Source property, set the AnimatedSource attached property to the image you want:

<Window x:Class="WpfAnimatedGif.Demo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:anim="https://github.com/whistyun/AnimatedImage.Wpf"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Image anim:ImageBehavior.AnimatedSource="Images/animated.gif" />

You can also specify the repeat behavior (the default is 0x, which means it will use the repeat count from the GIF metadata):

<Image anim:ImageBehavior.RepeatBehavior="3x"
       anim:ImageBehavior.AnimatedSource="Images/animated.gif" />

And of course you can also set the image in code:

var image = new BitmapImage();
image.BeginInit();
image.UriSource = new Uri(fileName);
image.EndInit();
ImageBehavior.SetAnimatedSource(img, image);

How to use (AvaloniaUI)

It has some compatibility with WPF: set the AnimatedSource attached property to the image you want:

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:anim="https://github.com/whistyun/AnimatedImage.Avalonia"
        Title="MainWindow" Height="350" Width="525">
    <Image anim:ImageBehavior.AnimatedSource="avares://MyLib/Images/animated.gif" />

You can also specify the repeat behavior (the default is 0x, which means it will use the repeat count from the GIF metadata):

<Image anim:ImageBehavior.RepeatBehavior="3x"
       anim:ImageBehavior.AnimatedSource="Images/animated.gif" />
