boost::gil::PixelIteratorConcept
An STL random access traversal iterator over a model of PixelConcept.
Synopsis
Declared in <boost/gil/concepts/pixel_iterator.hpp>
template<typename Iterator>
struct PixelIteratorConcept;Description
GIL's iterators must also provide the following metafunctions:
-
const_iterator_type<Iterator>Returns a read‐only equivalent ofIterator -
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.
