Rendering Effectlist always gives InvalidcastException

[SeriousGeorge]

I try to render multiple effects as a list (the amount and order of the effects can be dynamic). But everytime I render more than the Source it throws an InvalidCastException.

Working code with source only: ` applicationData = ApplicationData.Current; localFolder = applicationData.LocalFolder; imageFile = await localFolder.GetFileAsync("pic.jpg"); IAsyncOperation stream = FileIO.ReadBufferAsync(imageFile);

        var scale = new ScaleEffect(2);
        var rotation = new RotationEffect(30);
        var blur = new BlurEffect(10);

        using (var source = new BufferProviderImageSource(stream.AsBufferProvider()))
        {
            EffectList list = new EffectList() {Source = source};
            using (WriteableBitmapRenderer renderer = new WriteableBitmapRenderer(list))
            {
                renderer.OutputOption = OutputOption.PreserveAspectRatio;
                renderer.WriteableBitmap = new WriteableBitmap(1024,768);

                WriteableBitmap wp = await renderer.RenderAsync();
                imageControl.Source = wp;
            }
        }

`

Not working with list: ` applicationData = ApplicationData.Current; localFolder = applicationData.LocalFolder; imageFile = await localFolder.GetFileAsync("pic.jpg"); IAsyncOperation stream = FileIO.ReadBufferAsync(imageFile);

        var scale = new ScaleEffect(2);
        var rotation = new RotationEffect(30);
        var blur = new BlurEffect(10);

        using (var source = new BufferProviderImageSource(stream.AsBufferProvider()))
        {
            EffectList list = new EffectList() {source,scale,rotation,blur};
            using (WriteableBitmapRenderer renderer = new WriteableBitmapRenderer(list))
            {
                renderer.OutputOption = OutputOption.PreserveAspectRatio;
                renderer.WriteableBitmap = new WriteableBitmap(1024,768);

                WriteableBitmap wp = await renderer.RenderAsync();
                imageControl.Source = wp;
            }
        }

`

I also tried with JpegRenderer... same result. Additionally I can't find any complete sample using EffectList().

In your second code sample you are not actually setting a source. You are just sending in a list of four items. Try something like this:

EffectList list = new EffectList() {scale,rotation,blur}; list.Source = source;

Wow, that was quick. Thanks a lot! It's working now.
