Yes, this way you don't have a device description.

you can combine
    PreviewImage.DataDescription:=GetDescriptionFromDevice(0, 0, 0);
    PreviewImage.SetSize(PreviewWidth*32, PreviewHeight*32);
to
    PreviewImage.DataDescription:=GetDescriptionFromDevice(
      0, PreviewWidth*32, PreviewHeight*32);

btw, why the *32 ?
