Generic Image Library: planar_pixel_iterator Struct Template Reference

Modules | Alphabetical List | Class List | Directories | File List | GIL Home Page # planar_pixel_iterator Struct Template Reference [planar_pixel_iterator, planar_pixel_iterator, Models] `#include <planar_pixel_iterator.hpp>` List of all members. ## Detailed Description ### template<typename ChannelPtr, typename ColorSpace> struct boost::gil::planar_pixel_iterator< ChannelPtr, ColorSpace > An iterator over planar pixels. Models HomogeneousColorBaseConcept, PixelIteratorConcept, HomogeneousPixelBasedConcept, MemoryBasedIteratorConcept, HasDynamicXStepTypeConcept. Planar pixels have channel data that is not consecutive in memory. To abstract this we use classes to represent references and pointers to planar pixels.

## Constructor & Destructor Documentation
planar_pixel_iterator | ( | P * | pix | ) | `[inline]`
Copy constructor and operator= from pointers to compatible planar pixels or planar pixel references. That allow constructs like pointer = &value or pointer = &reference Since we should not override operator& that's the best we can do. ## 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 struct was generated from the following file: planar_pixel_iterator.hpp
