@Name(value="cv::Scalar_<double>")
public static class opencv_core.Scalar
extends opencv_core.AbstractScalar

\brief Template class for a 4-element vector derived from Vec.

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.
