@aws-cdk/aws-medialive-alpha.CaptionFontSize

Experimental

@aws-cdk/aws-medialive-alpha is an experimental (alpha) package: its API may change in any release, without a major version bump.

CaptionFontSize Class

Font size for burn-in and DVB-Sub captions.

Use {@link CaptionFontSize.AUTO} to scale the font size with the output resolution, or {@link CaptionFontSize.of} to set an exact size in points.
