How do I get an animated gif to work in WPF?

Question

What control type should I use - Image, MediaElement, etc.?

Answer 1

I couldn't get the most popular answer to this question (above by Dario) to work properly. The result was weird, choppy animation with weird artifacts. Best solution I have found so far: https://github.com/XamlAnimatedGif/WpfAnimatedGif

You can install it with NuGet

PM> Install-Package WpfAnimatedGif

and to use it, at a new namespace to the Window where you want to add the gif image and use it as below

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:gif="http://wpfanimatedgif.codeplex.com" <!-- THIS NAMESPACE -->
    Title="MainWindow" Height="350" Width="525">

<Grid>
    <!-- EXAMPLE USAGE BELOW -->
    <Image gif:ImageBehavior.AnimatedSource="Images/animated.gif" />

The package is really neat, you can set some attributes like below

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

and you can use it in your code as well:

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

EDIT: Silverlight support

As per josh2112's comment if you want to add animated GIF support to your Silverlight project then use github.com/XamlAnimatedGif/XamlAnimatedGif

I post a solution extending the image control and using the Gif Decoder. The gif decoder has a frames property. I animate the FrameIndex property. The event ChangingFrameIndex changes the source property to the frame corresponding to the FrameIndex (that is in the decoder). I guess that the gif has 10 frames per second.

class GifImage : Image
{
    private bool _isInitialized;
    private GifBitmapDecoder _gifDecoder;
    private Int32Animation _animation;

    public int FrameIndex
    {
        get { return (int)GetValue(FrameIndexProperty); }
        set { SetValue(FrameIndexProperty, value); }
    }

    private void Initialize()
    {
        _gifDecoder = new GifBitmapDecoder(new Uri("pack://application:,,," + this.GifSource), BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
        _animation = new Int32Animation(0, _gifDecoder.Frames.Count - 1, new Duration(new TimeSpan(0, 0, 0, _gifDecoder.Frames.Count / 10, (int)((_gifDecoder.Frames.Count / 10.0 - _gifDecoder.Frames.Count / 10) * 1000))));
        _animation.RepeatBehavior = RepeatBehavior.Forever;
        this.Source = _gifDecoder.Frames[0];

        _isInitialized = true;
    }

    static GifImage()
    {
        VisibilityProperty.OverrideMetadata(typeof (GifImage),
            new FrameworkPropertyMetadata(VisibilityPropertyChanged));
    }

    private static void VisibilityPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        if ((Visibility)e.NewValue == Visibility.Visible)
        {
            ((GifImage)sender).StartAnimation();
        }
        else
        {
            ((GifImage)sender).StopAnimation();
        }
    }

    public static readonly DependencyProperty FrameIndexProperty =
        DependencyProperty.Register("FrameIndex", typeof(int), typeof(GifImage), new UIPropertyMetadata(0, new PropertyChangedCallback(ChangingFrameIndex)));

    static void ChangingFrameIndex(DependencyObject obj, DependencyPropertyChangedEventArgs ev)
    {
        var gifImage = obj as GifImage;
        gifImage.Source = gifImage._gifDecoder.Frames[(int)ev.NewValue];
    }

    /// <summary>
    /// Defines whether the animation starts on it's own
    /// </summary>
    public bool AutoStart
    {
        get { return (bool)GetValue(AutoStartProperty); }
        set { SetValue(AutoStartProperty, value); }
    }

    public static readonly DependencyProperty AutoStartProperty =
        DependencyProperty.Register("AutoStart", typeof(bool), typeof(GifImage), new UIPropertyMetadata(false, AutoStartPropertyChanged));

    private static void AutoStartPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        if ((bool)e.NewValue)
            (sender as GifImage).StartAnimation();
    }

    public string GifSource
    {
        get { return (string)GetValue(GifSourceProperty); }
        set { SetValue(GifSourceProperty, value); }
    }

    public static readonly DependencyProperty GifSourceProperty =
        DependencyProperty.Register("GifSource", typeof(string), typeof(GifImage), new UIPropertyMetadata(string.Empty, GifSourcePropertyChanged));

    private static void GifSourcePropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        (sender as GifImage).Initialize();
    }

    /// <summary>
    /// Starts the animation
    /// </summary>
    public void StartAnimation()
    {
        if (!_isInitialized)
            this.Initialize();

        BeginAnimation(FrameIndexProperty, _animation);
    }

    /// <summary>
    /// Stops the animation
    /// </summary>
    public void StopAnimation()
    {
        BeginAnimation(FrameIndexProperty, null);
    }
}

Usage example (XAML):

<controls:GifImage x:Name="gifImage" Stretch="None" GifSource="/SomeImage.gif" AutoStart="True" />

Answer 3

How about this tiny app: Code behind:

public MainWindow()
{
  InitializeComponent();
  Files = Directory.GetFiles(@"I:\images");
  this.DataContext= this;
}
public string[] Files
{get;set;}

XAML:

<Window x:Class="PicViewer.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="175" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
        <ListBox x:Name="lst" ItemsSource="{Binding Path=Files}"/>
        <MediaElement Grid.Column="1" LoadedBehavior="Play" Source="{Binding ElementName=lst, Path=SelectedItem}" Stretch="None"/>
    </Grid>
</Window>

Answer 4

I, too, did a search and found several different solution in just a thread on the old MSDN forums. (link no longer worked so I removed it)

The simplest to execute seems to be to use a WinForms PictureBox control, and went like this (changed a few things from the thread, most of it the same).

Add a reference to System.Windows.Forms, WindowsFormsIntegration, and System.Drawing to your project first.

<Window x:Class="GifExample.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
    xmlns:winForms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
    Loaded="Window_Loaded" >
    <Grid>
        <wfi:WindowsFormsHost>
            <winForms:PictureBox x:Name="pictureBoxLoading">
            </winForms:PictureBox>
        </wfi:WindowsFormsHost>
    </Grid>
</Window >

Then in the Window_Loaded handler, you would set the pictureBoxLoading.ImageLocation property to the image file path that you want to show.

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    pictureBoxLoading.ImageLocation = "../Images/mygif.gif";
}

The MediaElement control was mentioned in that thread, but it is also mentioned that it is a rather heavy control, so there were a number of alternatives, including at least 2 homebrewed controls based on the Image control, so this is the simplest.

Answer 5

Its very simple if you use <MediaElement>:

<MediaElement  Height="113" HorizontalAlignment="Left" Margin="12,12,0,0" 
Name="mediaElement1" VerticalAlignment="Top" Width="198" Source="C:\Users\abc.gif"
LoadedBehavior="Play" Stretch="Fill" SpeedRatio="1" IsMuted="False" />

Answer 6

Here is my version of animated image control. You can use standard property Source for specifying image source. I further improved it. I am a russian, project is russian so comments are also in Russian. But anyway you should be able understand everything without comments. :)

/// <summary>
/// Control the "Images", which supports animated GIF.
/// </summary>
public class AnimatedImage : Image
{
    #region Public properties

    /// <summary>
    /// Gets / sets the number of the current frame.
    /// </summary>
    public int FrameIndex
    {
        get { return (int) GetValue(FrameIndexProperty); }
        set { SetValue(FrameIndexProperty, value); }
    }

    /// <summary>
    /// Gets / sets the image that will be drawn.
    /// </summary>
    public new ImageSource Source
    {
        get { return (ImageSource) GetValue(SourceProperty); }
        set { SetValue(SourceProperty, value); }
    }

        BitmapImage lBitmapImage = aEventArgs.NewValue as BitmapImage;

Answer 7

I use this library: https://github.com/XamlAnimatedGif/WpfAnimatedGif

First, install library into your project (using Package Manager Console):

    PM > Install-Package WpfAnimatedGif

Then, use this snippet into XAML file:

    <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:gif="http://wpfanimatedgif.codeplex.com"
        Title="MainWindow" Height="350" Width="525">
        <Grid>
            <Image gif:ImageBehavior.AnimatedSource="Images/animated.gif" />
        ...

I hope helps.

I modified Mike Eshva's code,And I made it work better.You can use it with either 1frame jpg png bmp or mutil-frame gif.If you want bind a uri to the control,bind the UriSource properties or you want bind any in-memory stream that you bind the Source propertie which is a BitmapImage.

This is a custom control. You need to create it in WPF App Project,and delete the Template override in style.

Basically the same PictureBox solution above, but this time with the code-behind to use an Embedded Resource in your project:

In XAML:

<WindowsFormsHost x:Name="_loadingHost">
  <Forms:PictureBox x:Name="_loadingPictureBox"/>
</WindowsFormsHost>

In Code-Behind:

public partial class ProgressIcon
{
    public ProgressIcon()
    {
        InitializeComponent();
        var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("My.Namespace.ProgressIcon.gif");
        var image = System.Drawing.Image.FromStream(stream);
        Loaded += (s, e) => _loadingPictureBox.Image = image;
    }
}

Answer 10

I had this issue, until I discovered that in WPF4, you can simulate your own keyframe image animations. First, split your animation into a series of images, title them something like "Image1.gif", "Image2,gif", and so on. Import those images into your solution resources. I'm assuming you put them in the default resource location for images.

You are going to use the Image control. Use the following XAML code. I've removed the non-essentials.

<Image Name="Image1">
   <Image.Triggers>
      <EventTrigger RoutedEvent="Image.Loaded"
         <EventTrigger.Actions>
            <BeginStoryboard>
               <Storyboard>
                   <ObjectAnimationUsingKeyFrames Duration="0:0:1" Storyboard.TargetProperty="Source" RepeatBehavior="Forever">
                      <DiscreteObjectKeyFrames KeyTime="0:0:0">
                         <DiscreteObjectKeyFrame.Value>
                            <BitmapImage UriSource="Images/Image1.gif"/>
                         </DiscreteObjectKeyFrame.Value>
                      </DiscreteObjectKeyFrames>
                     <DiscreteObjectKeyFrames KeyTime="0:0:0.25">

Answer 11

An alternative to waiting animation in WPF is:

 <ProgressBar Height="20" Width="100" IsIndeterminate="True"/>

It will show an animated progress bar.

Answer 12

Thanks for your post Joel, it helped me solve WPF's absence of support for animated GIFs. Just adding a little code since I had a heck of a time with setting the pictureBoxLoading.Image property due to the Winforms api.

I had to set my animated gif image's Build Action as "Content" and the Copy to output directory to "Copy if newer" or "always". Then in the MainWindow() I called this method. Only issue is that when I tried to dispose of the stream, it gave me a red envelope graphic instead of my image. I'll have to solve that problem. This removed the pain of loading a BitmapImage and changing it into a Bitmap (which obviously killed my animation because it is no longer a gif).

private void SetupProgressIcon()
{
   Uri uri = new Uri("pack://application:,,,/WPFTest;component/Images/animated_progress_apple.gif");
   if (uri != null)
   {
      Stream stream = Application.GetContentStream(uri).Stream;   
      imgProgressBox.Image = new System.Drawing.Bitmap(stream);
   }
}

Usage:

<localComponents:GifImage x:Name="gifImage" IsAutoStart="True" GifSource="{Binding Path=value}" />

As it would not cause memory leak and it animated the gif image own time line, you can try it.

Answer 14

I suggest using the WebBrowser control.

If the gif is on the web, you can set the source in XAML:

<WebBrowser Source="https://media.giphy.com/media/Ent2j55lyQipa/giphy.gif" />

If it is a local file you can create the Source from code-behind.

XAML:

<WebBrowser x:Name="WebBrowser" />

Code-behind:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    string curDir = Directory.GetCurrentDirectory();
    this.WebBrowser.Source = new Uri(String.Format("file:///{0}/10-monkey.gif", curDir));
}

Answer 15

Previously, I faced a similar problem, I needed to play .gif file in your project. I had two choices:

• using PictureBox from WinForms

• using a third-party library, such as WPFAnimatedGif from codeplex.com.

Version with PictureBox did not work for me, and the project could not use external libraries for it. So I made it for myself through Bitmap with help ImageAnimator. Because, standard BitmapImage does not support playback of .gif files.

Full example:

XAML

<Window x:Class="PlayGifHelp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" Loaded="MainWindow_Loaded">

    <Grid>
        <Image x:Name="SampleImage" />
    </Grid>
</Window>

Code behind

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    Bitmap _bitmap;
    BitmapSource _source;

    private BitmapSource GetSource()
    {
        if (_bitmap == null)
        {
            string path = Directory.GetCurrentDirectory();

            // Check the path to the .gif file
            _bitmap = new Bitmap(path + @"\anim.gif");
        }

        IntPtr handle = IntPtr.Zero;
        handle = _bitmap.GetHbitmap();

        return Imaging.CreateBitmapSourceFromHBitmap(handle, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
    }

    private void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {
        _source = GetSource();
        SampleImage.Source = _source;
        ImageAnimator.Animate(_bitmap, OnFrameChanged);
    }

    private void FrameUpdatedCallback()
    {
        ImageAnimator.UpdateFrames();

        if (_source != null)
        {
            _source.Freeze();
        }

        _source = GetSource();

        SampleImage.Source = _source;
        InvalidateVisual();
    }

    private void OnFrameChanged(object sender, EventArgs e)
    {
        Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(FrameUpdatedCallback));
    }
}

Bitmap does not support URI directive, so I load .gif file from the current directory.

Answer 16

Small improvement of GifImage.Initialize() method, which reads proper frame timing from GIF metadata.

    private void Initialize()
    {
        _gifDecoder = new GifBitmapDecoder(new Uri("pack://application:,,," + this.GifSource), BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);

        int duration=0;
        _animation = new Int32AnimationUsingKeyFrames();
        _animation.KeyFrames.Add(new DiscreteInt32KeyFrame(0, KeyTime.FromTimeSpan(new TimeSpan(0))));
        foreach (BitmapFrame frame in _gifDecoder.Frames)
        {
            BitmapMetadata btmd = (BitmapMetadata)frame.Metadata;
            duration += (ushort)btmd.GetQuery("/grctlext/Delay");
            _animation.KeyFrames.Add(new DiscreteInt32KeyFrame(_gifDecoder.Frames.IndexOf(frame)+1, KeyTime.FromTimeSpan(new TimeSpan(duration*100000))));
        }            
         _animation.RepeatBehavior = RepeatBehavior.Forever;
        this.Source = _gifDecoder.Frames[0];            
        _isInitialized = true;
    }

Answer 17

I am not sure if this has been solved but the best way is to use the WpfAnimatedGid library. It is very easy, simple and straight forward to use. It only requires 2lines of XAML code and about 5 lines of C# Code in the code behind.

You will see all the necessary details of how this can be used there. This is what I also used instead of re-inventing the wheel

Answer 18

Adding on to the main response that recommends the usage of WpfAnimatedGif, you must add the following lines in the end if you are swapping an image with a Gif to ensure the animation actually executes:

ImageBehavior.SetRepeatBehavior(img, new RepeatBehavior(0));
ImageBehavior.SetRepeatBehavior(img, RepeatBehavior.Forever);

So your code will look like:

var image = new BitmapImage();
image.BeginInit();
image.UriSource = new Uri(fileName);
image.EndInit();
ImageBehavior.SetAnimatedSource(img, image);
ImageBehavior.SetRepeatBehavior(img, new RepeatBehavior(0));
ImageBehavior.SetRepeatBehavior(img, RepeatBehavior.Forever);

You could try using a WebBrowser UI Control and setting the html string to an HTML image tag...

XML:

    <WebBrowser Name="webBrowser1"/>

C#: f

    webBrowser1.NavigateToString(        
      @"<img src=""arrow-24.png""/>"
    );

i have some simple solution for animate gif images as separated frames. All u need is - to pass List of images in new class:

class AniImage: Image
    {
        private Int32Animation ani = new Int32Animation(); 
        private List<Image> images; 
        public int duration { get; set; } 
        static FrameworkPropertyMetadata metadata = new FrameworkPropertyMetadata(new PropertyChangedCallback(ChangedCallbackMethod));
        public static readonly DependencyProperty frameProperty = DependencyProperty.Register("Frame", typeof(int), typeof(AniImage), metadata);
        static void ChangedCallbackMethod(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {            
            AniImage ai = (AniImage)d; 
            int curFrame = (int)e.NewValue; 
            ai.Source = ai.images[curFrame].Source; 
        }            
        public int Frame
        {
            get { return (int)GetValue(frameProperty); }
            set { SetValue(frameProperty, value); }
        }
        public AniImage(List<Image> imgs)
        {
            images = imgs; 
            duration = 2; 
            Frame = 0; 
            this.Source = imgs[0].Source;                
            if(images.Count > 1)
            {
                ani.From = 0;
                ani.To = images.Count - 1;
                ani.By = 1;
                ani.Duration = TimeSpan.FromSeconds(duration);
                ani.RepeatBehavior = RepeatBehavior.Forever;
                BeginAnimation(frameProperty, ani); 
            }           
        }
    }

For create new object:

        List<Image> imagesList = new List<Image>();
        string[] imgNames = {
            "Resources/spaceship021.gif",
            "Resources/spaceship022.gif",
            "Resources/spaceship023.gif",
            "Resources/spaceship024.gif",
            "Resources/spaceship025.gif" };

        foreach (string s in imgNames)
        {
            Image img = new Image();
            img.Source = new BitmapImage(new Uri(s, UriKind.Relative));
            imagesList.Add(img);
        }

        ship = new AniImage(imagesList);

        ship.Width = 100;
        ship.Height = 100;
        Canvas.SetLeft(ship, 250);
        Canvas.SetBottom(ship, 50);
        field.Children.Add(ship);
