## Member Function Documentation
reference operator[] | ( | difference_type | d | ) | const`[inline]`
For some reason operator[] provided by iterator_facade returns a custom class that is convertible to reference We require our own reference because it is registered in iterator_traits The documentation for this class was generated from the following file: pixel_iterator_adaptor.hpp
