## Detailed Description

template<typename Iterator>
struct boost::gil::PixelIteratorConcept< Iterator >

An STL random access traversal iterator over a model of PixelConcept.

GIL's iterators must also provide the following metafunctions:

- `const_iterator_type<Iterator>`: Returns a read-only equivalent of `Iterator`
- `iterator_is_mutable<Iterator>`: Returns whether the given iterator is read-only or mutable
- `is_iterator_adaptor<Iterator>`: Returns whether the given iterator is an adaptor over another iterator. See IteratorAdaptorConcept for additional requirements of adaptors.

typename const_iterator_type<It>::type;
where PixelIteratorConcept<const_iterator_type<It>::type>;
static const bool iterator_is_mutable<It>::value;
static const bool is_iterator_adaptor<It>::value; // is it an iterator adaptor
};
