List of all members.

## Detailed Description

### template<typename D>
struct boost::gil::PixelDereferenceAdaptorConcept< D >

Represents a unary function object that can be invoked upon dereferencing a pixel iterator.

DEREFERENCE ADAPTOR CONCEPTS This can perform an arbitrary computation, such as color conversion or table lookup

    concept PixelDereferenceAdaptorConcept<boost::UnaryFunctionConcept D>
      : DefaultConstructibleConcept<D>, CopyConstructibleConcept<D>, AssignableConcept<D>  {
        typename const_t;         where PixelDereferenceAdaptorConcept<const_t>;
        typename value_type;      where PixelValueConcept<value_type>;
        typename reference;         // may be mutable
        typename const_reference;   // must not be mutable
        static const bool D::is_mutable;

        where Convertible<value_type,result_type>;
