How to get system's closed caption font size?
问题 I want to get system's closed caption font style, and I referd doc. So far everything is good, except the font size. According to doc, ClosedCaptionProperties.FontSize returns enum ClosedCaptionSize , see code switch (Windows.Media.ClosedCaptioning.ClosedCaptionProperties.FontSize) { case Windows.Media.ClosedCaptioning.ClosedCaptionSize.FiftyPercent: richtextblock.FontSize = 50; break; case Windows.Media.ClosedCaptioning.ClosedCaptionSize.OneHundredPercent: richtextblock.FontSize = 100; break
