AnimatedImage/AnimatedImage/FrameRenderer.cs

Line 111 in cf66270

stream.Position = 0;

solution:

            var position = stream.Position;
            stream.Position = 0;
            var magic = new byte[Signature.MaxLength];
            stream.Read(magic, 0, magic.Length);
            if (Signature.IsGifSignature(magic))
            {
                stream.Position = 0;
                var gif = new GifFile(stream);
                renderer = new GifRenderer(gif, factory);

                return true;
            }
            else
            {
                stream.Position = position;
            }
