List of all members.
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
