Detailed Description

template<typename TImage>
class itk::ReflectiveImageRegionIterator< TImage >

Multi-dimensional image iterator which only walks a region.

ReflectiveImageRegionIterator is a templated class to represent a multi-dimensional iterator. ReflectiveImageRegionIterator is templated over the image type ReflectiveImageRegionIterator is constrained to walk only within the specified region and along a line parallel to one of the coordinate axis.

Most of the functionality is inherited from the ReflectiveImageRegionConstIterator. The current class only adds write access to image pixels.

Constructor & Destructor Documentation

template<typename TImage> itk::ReflectiveImageRegionIterator< TImage >::ReflectiveImageRegionIterator (   )

Default constructor. Needed since we provide a cast constructor.

template<typename TImage> itk::ReflectiveImageRegionIterator< TImage >::ReflectiveImageRegionIterator (  ImageType *  ptr, const RegionType &  region )

Constructor establishes an iterator to walk a particular image and a particular region of that image.

template<typename TImage> itk::ReflectiveImageRegionIterator< TImage >::ReflectiveImageRegionIterator (  const ImageIteratorWithIndex< TImage > &  it  )

Constructor that can be used to cast from an ImageIterator to an ReflectiveImageRegionIterator. Many routines return an ImageIterator but for a particular task, you may want an ReflectiveImageRegionIterator. Rather than provide overloaded APIs that return different types of Iterators, itk returns ImageIterators and uses constructors to cast from an ImageIterator to a ReflectiveImageRegionIterator.

template<typename TImage> the construction from a const iterator is declared protected in order to enforce const correctness* itk::ReflectiveImageRegionIterator< TImage >::ReflectiveImageRegionIterator (  const ReflectiveImageRegionConstIterator< TImage > &  it  )  [protected]

template<typename TImage> itk::ImageConstIteratorWithIndex< TImage >::itkStaticConstMacro (  ImageDimension  , unsigned  int, TImage::ImageDimension  )  [inherited]

Dimension of the image the iterator walks. This constant is needed so functions that are templated over image iterator type (as opposed to being templated over pixel type and dimension) can have compile time access to the dimension of the image that the iterator walks.

template<typename TImage> Self& itk::ReflectiveImageRegionConstIterator< TImage >::operator++ (   )  [inherited]

Increment (prefix) the fastest moving dimension of the iterator's index. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the end of the row of the region to the beginning of the next row of the region) up until the iterator tries to moves past the last pixel of the region. Here, the iterator will be set to be one pixel past the end of the region. See also: operator++(int)
