Display GIF in a WP7 application with Silverlight

I would like to display gif in my WP7 application. Is there some way to achieve this ?

I've tryed this one http://imagetools.codeplex.com/ but can't make it working with WP7.

Thanks in advance for any help

Solution 1:

In fact, it's working, but it lacks some documentation.

After some troubles, here's how to use it :

reference ImageTools
reference ImageTools.Controls
reference ImageTools.IO.Gif

Add namespace in xaml :

xmlns:imagetools="clr-namespace:ImageTools.Controls;assembly=ImageTools.Controls"

And resources :

<phone:PhoneApplicationPage.Resources>
    <imagetools:ImageConverter x:Key="ImageConverter" />
</phone:PhoneApplicationPage.Resources>

Then use the control with the converter :

<imagetools:AnimatedImage Source="{Binding ImageSource, Converter={StaticResource ImageConverter}}" />

Your ImageSource should be an Uri, for example :

ImageSource = new Uri("http://mysite/my.gif", UriKind.Absolute);

Don't forget to add decoded :

ImageTools.IO.Decoders.AddDecoder<GifDecoder>();

Check out Jamie Rodriguez's post here on using GIFs with WP7. He uses the ImageTools project from CodePlex.

I struggled to get the accepted answer working. The following solution worked for me to display a static gif.

    public ImageResponse(string imageUrl)
    {
        InitializeComponent();

        ImageTools.IO.Decoders.AddDecoder<GifDecoder>();

        var imageResponse = new ExtendedImage();
        imageResponse.UriSource = new Uri(imageUrl);

        imageResponse.LoadingCompleted += this.ImageResponseLoadingCompleted;
    }

    private void ImageResponseLoadingCompleted(object sender, EventArgs e)
    {
        var imageResponse = (ExtendedImage)sender;

        Classes.Util.UiThread.Invoke(() =>
            {
                this.ImageResponse.Source = imageResponse.ToBitmap();
            });
    }

Classes.Util.UiThread is a helper class I use to call the UI Thread

this.ImageResponse is a standard image control

Solution 4:

Is it an animated GIF? If not, I would try converting the GIF to another supported file format before using it in your app.

Solution 5:

WP7 Silverlight supports JPG/PNG.
