List of all members.


Detailed Description

template<typename Derived, typename Iterator, typename SFn>
class boost::gil::detail::step_iterator_adaptor< Derived, Iterator, SFn >

An adaptor over an existing iterator that changes the step unit.

(i.e. distance(it,it+1)) by a given predicate. Instead of calling base's operators ++, --, +=, -=, etc. the adaptor is using the passed policy object SFn for advancing and for computing the distance between iterators.
