Xamarin SignaturePadView GetImage Android Black Background

I always get a black background color, even when I set it to white:

  SignaturePadView sigView = new SignaturePadView(Forms.Context);
  sigView.StrokeColor = Color.Black;
  sigView.BackgroundColor = Color.White;
  var stream = await sigView.GetImageStreamAsync(SignatureImageFormat.Jpeg);

It is working on iOS, but Android doesn't. Is there something else I can do to get a white background?

EDIT: The resulting jpg-file has a black background, not the view!

Saving transparent layer in jpg results in black background. Save in png instead to keep the alpha layer.

Can you try using GetImage method of the Signature pad View ?

sigView.GetImage(Android.Graphics.Color.Black, Android.Graphics.Color.White, false);

We uses this and gets in white background with black signature.
