Being derived from ``Vec<_Tp, 4>`` , ``Scalar_`` and ``Scalar`` can be used just as typical 4-element vectors. In addition, they can be converted to/from ``CvScalar`` . The type ``Scalar`` is widely used in OpenCV to pass pixel values. Being derived from ``Vec<_Tp, 4>`` , ``Scalar_`` and ``Scalar`` can be used just as typical 4-element vectors.
