Detailed Description

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

Multi-dimensional image iterator.

ImageReverseConstIterator is a templated class to represent a multi-dimensional iterator. ImageReverseConstIterator is templated over the dimension of the image and the data type of the image.

ImageReverseConstIterator is a base class for all the reverse image iterators. It provides the basic construction and comparison operations. However, it does not provide mechanisms for moving the iterator. A subclass of ImageReverseConstIterator must be used to move the iterator.

ImageReverseConstIterator is a multi-dimensional iterator, requiring more information be specified before the iterator can be used than conventional iterators. Whereas the std::vector::iterator from the STL only needs to be passed a pointer to establish the iterator, the multi-dimensional image iterator needs a pointer, the size of the buffer, the size of the region, the start index of the buffer, and the start index of the region. To gain access to this information, ImageReverseConstIterator holds a reference to the image over which it is traversing.

ImageReverseConstIterator assumes a particular layout of the image data. In particular, the data is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.

MORE INFORMATION: For a complete description of the ITK Image Iterators and their API, please see the Iterators chapter in the ITK Software Guide. The ITK Software Guide is available in print and as a free .pdf download from http://www.itk.org.

template<typename TImage>

itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator ( ImageType * ptr,

const RegionType & region

) [inline]

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

References itk::ImageReverseConstIterator< TImage >::IndexType, itk::ImageReverseConstIterator< TImage >::RegionType, and itk::ImageReverseConstIterator< TImage >::SizeType.

template<typename TImage>

itk::ImageReverseConstIterator< TImage >::ImageReverseConstIterator ( const ImageConstIterator< TImage > & it ) [inline]

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

template<typename TImage>

const IndexType itk::ImageReverseConstIterator< TImage >::GetIndex ( void ) [inline]

template<typename TImage>

itk::ImageReverseConstIterator< TImage >::itkStaticConstMacro ( ImageIteratorDimension ,

unsigned int,

TImage::ImageDimension

)

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>

bool itk::ImageReverseConstIterator< TImage >::operator!= ( const Self & it ) const [inline]

Comparison operator. Two iterators are the same if they "point to" the same memory location
