Class Scalar

  org.opencv.core.Scalar

public class Scalar
extends java.lang.Object

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

template class Scalar_ : public Vec<_Tp, 4> {... };

// C++ code:

typedef Scalar_ Scalar;

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.
