Detailed Description

template<typename Loc2>
class boost::gil::iterator_from_2d< Loc2 >

Provides 1D random-access navigation to the pixels of the image. 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:
