public DvbSubDestinationSettings withShadowOpacity(Integer shadowOpacity) {

        return this;
    }
Specify the opacity of the shadow. Enter a value from 0 to 255, where 0 is transparent and 255 is opaque. If
Style passthrough is set to Enabled, leave Shadow opacity blank to pass through the shadow style information in
your input captions to your output captions. If Style passthrough is set to disabled, leave blank to use a value
of 0 and remove all shadows from your output captions. Within your job settings, all of your DVB-Sub settings must
be identical.
