XamlAnimatedGif / WpfAnimatedGif

Gif are not animated when the BitmapImage is already downloaded when settting animation source

Could you give more details on how to reproduce the issue?

I was wrong, it is not when image is already loaded. It happen when the BitmapImage is already downloaded.
if I do

ImageModule.BitmapImage.DownloadCompleted += (e, a) =>
 {
       ImageBehavior.SetAnimatedSource(image, ImageModule.BitmapImage);
  };

There will be no animation. When I set the AnimatedSource when BitmapImage.IsDownloading is true, the animation will work.

I don't have this problem with XamlAnimatedGif but the animation is too slow with this library.

I got an AnimationLoaded event but GetAnimationController return null. So I must reach this part of the code

WpfAnimatedGif/WpfAnimatedGif/ImageBehavior.cs

Lines 408 to 412 in 5e30f4e

    
           if (source != null) 
        
           { 
        
               SetIsAnimationLoaded(imageControl, true); 
        
               imageControl.RaiseEvent(new RoutedEventArgs(AnimationLoadedEvent, imageControl)); 
        
           }

My BitmapImage use a stream source and not a Uri so

WpfAnimatedGif/WpfAnimatedGif/ImageBehavior.cs

Line 369 in 5e30f4e

bool isLoadingDeferred = IsLoadingDeferred(source);

must be false.

OK, so there seems to be multiple problems... Not sure where it's coming from. If you could provide a short but complete example that reproduces the issue, it would be very helpful.

I did some debbuging and in the end the problem didn't came from your library. My BitmapSource reference was changed so when I setted set animation source at different time I ended up setting a different source and one was corrupted.

I'm glad you were able to solve your problem. Thanks for letting me know!

	if (source != null)
	{
	SetIsAnimationLoaded(imageControl, true);
	imageControl.RaiseEvent(new RoutedEventArgs(AnimationLoadedEvent, imageControl));
	}
