nth_channel_deref_fn Struct Template Reference [Models] #include <image_view_factory.hpp> List of all members. Detailed Description template<typename SrcP> struct boost::gil::detail::nth_channel_deref_fn< SrcP > Function object that returns a grayscale reference of the N-th channel of a given reference. Models: PixelDereferenceAdaptorConcept. If the input is a pixel value or constant reference, the function object is immutable. Otherwise it is mutable (and returns non-const reference to the n-th channel).
