this is my code :

here are the decoder statements at the top of the page:


ex_img = new ExtendedImage();
            ex_img.LoadingCompleted += ExtendedImage_LoadingCompleted;
            ex_img.UriSource = new Uri("/Images/0_0.gif",UriKind.Relative);
        private void ExtendedImage_LoadingCompleted(object sender, EventArgs e)
            ExtendedImage image = (ExtendedImage)sender;
            Dispatcher.BeginInvoke(() =>
                                       var bitmap = image.ToBitmap();
                                           im.Source = bitmap;
            // Image is now loaded.


error :
