template<class T1,class T2,class T3> inline T2       &second(      ColorSpace<T1,T2,T3> &x)
template<class T1,class T2,class T3> inline const T2 &second(const ColorSpace<T1,T2,T3> &x)

Second part (element-wise)

Returns

An array representing the second part of X

Remarks

This function supposes the existence of a function second applicable on each element. A function second is defined for color spaces of the library and for the STL pair structur. The function second has to be overloaded for any other classes, and should give a reference back, if a use as left-value is expected.
