Models: PixelIteratorConcept, PixelBasedConcept, HasDynamicXStepTypeConcept. Pixels are traversed from the top to the bottom row and from the left to the right within each row

## Member Function Documentation
reference operator[] | ( | difference_type | d | ) | const`[inline]`
For some reason operator[] provided by iterator_adaptor 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: iterator_from_2d.hpp
