Detailed Description

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

Multi-dimensional image iterator which only walks a region.

ImageRegionReverseIterator is a templated class to represent a multi-dimensional iterator. ImageRegionReverseIterator is templated over the image type ImageRegionReverseIterator 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 ImageRegionReverseConstIterator. The current class only adds write access to image pixels.

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.

Member Enumeration Documentation

template<typename TImage>

anonymous enum

inherited

Dimension of the image the iterator walks. This enum is needed so that 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.

Enumerator:

ImageIteratorDimension

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.

Definition at line 112 of file itkImageRegionReverseConstIterator.h.

Constructor & Destructor Documentation

template<typename TImage >

itk::ImageRegionReverseIterator< TImage >::ImageRegionReverseIterator ( )

Default constructor. Needed since we provide a cast constructor.

Definition at line 28 of file itkImageRegionReverseIterator.txx.

template<typename TImage >

itk::ImageRegionReverseIterator< TImage >::ImageRegionReverseIterator	(	ImageType *	ptr,
		const RegionType &	region
	)

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

Definition at line 38 of file itkImageRegionReverseIterator.txx.

template<typename TImage >

itk::ImageRegionReverseIterator< TImage >::ImageRegionReverseIterator ( const ImageConstIterator< TImage > & it )

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.

Definition at line 49 of file itkImageRegionReverseIterator.txx.

template<typename TImage >

itk::ImageRegionReverseIterator< TImage >::ImageRegionReverseIterator ( const ImageRegionReverseConstIterator< TImage > & it )

protected

the construction from a const iterator is declared protected in order to enforce const correctness.

Definition at line 56 of file itkImageRegionReverseIterator.txx.

template<typename TImage >

ImageRegionReverseIterator< TImage > itk::ImageRegionReverseIterator< TImage >::End ( void ) const

Return an iterator for the end of the region. "End" is defined as one pixel past the last pixel of the region.

Deprecated:: Use GoToEnd() instead

template<typename TImage>

static unsigned int itk::ImageReverseConstIterator< TImage >::GetImageIteratorDimension ( )

inlinestaticinherited

Definition at line 279 of file itkImageReverseConstIterator.h.

template<typename TImage>

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

Run-time type information (and related methods).

template<typename TImage>

const RegionType& itk::ImageReverseConstIterator< TImage >::GetRegion ( void ) const

inlineinherited

Definition at line 315 of file itkImageReverseConstIterator.h.

template<typename TImage>

void itk::ImageRegionReverseConstIterator< TImage >::GoToBegin ( void )

Move an iterator to the beginning of the region. "Begin" for a reverse iterator is the last pixel in the region.

template<typename TImage>

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

template<typename TImage>

Self& itk::ImageRegionReverseConstIterator< TImage >::operator++ ( )

inlineinherited

iterator's index. For a reverse iterator, this moves backwards through the region. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the start of the row of the region to the end of the previous row of the region) up until the iterator tries to moves before the first pixel of the region. Here, the iterator will be set to be one pixel before the start of the region.

See also:: operator++(int).

Definition at line 260 of file itkImageRegionReverseConstIterator.h.

template<typename TImage>

Self& itk::ImageRegionReverseConstIterator< TImage >::operator-- ( )

inlineinherited

Decrement (prefix) the fastest moving dimension of the iterator's index. For a reverse iterator, this moves forward through the region. 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 start 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.
