Namespace: vigra
According to the NTSC analog videa standard, the functor realizes the transformation
By default,
. This default can be overridden in the constructor. Y' represents the luminance ("brightness") of the color. The transformation is scaled so that the following bounds apply:
Traits defined:
the functor's argument type
the result's component type
the functor's result type
default constructor. The maximum value for each RGB component defaults to 255.
