Detailed Documentation
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.
Construction
Scalar_()
various constructors
Methods
Scalar_<_Tp> mul( const Scalar_<_Tp>& a, double scale = 1 ) const
per-element product
template <typename T2> operator Scalar_< T2 >() const
conversion to another data type
static Scalar_<_Tp> all(_Tp v0)
returns a scalar with all elements set to v0
