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.

concept PixelIteratorConcept<typename Iterator>
    : boost_concepts::RandomAccessTraversalConcept<Iterator>, PixelBasedConcept<Iterator>
{
    where PixelValueConcept<value_type>;
    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
};
