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

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.

Definition at line 113 of file itkImageRegionReverseConstIterator.h.

Constructor & Destructor Documentation

template<typename TImage >

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

Default constructor. Needed since we provide a cast constructor.

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.

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.

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.

Member Function Documentation

template<typename TImage >

Self itk::ImageRegionReverseIterator< TImage >::Begin ( void ) const

Return an iterator for the beginning of the region. "Begin" is defined as the first pixel in the region.

Deprecated:: Use GoToBegin() instead

Reimplemented from itk::ImageRegionReverseConstIterator< TImage >.

template<typename TImage >

Self 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

Reimplemented from itk::ImageRegionReverseConstIterator< TImage >.

const PixelType itk::ImageReverseConstIterator< TImage >::Get ( void ) const [inline, inherited]

Get the pixel value

Definition at line 323 of file itkImageReverseConstIterator.h.

static unsigned int itk::ImageReverseConstIterator< TImage >::GetImageIteratorDimension ( ) [inline, static, inherited]

Get the dimension (size) of the index.

Definition at line 283 of file itkImageReverseConstIterator.h.

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

Get the index. This provides a read only reference to the index. This causes the index to be calculated from pointer arithmetic and is therefore an expensive operation.

See also:: SetIndex

Definition at line 308 of file itkImageReverseConstIterator.h.

virtual const char* itk::ImageRegionReverseConstIterator< TImage >::GetNameOfClass ( ) const [virtual, inherited]

Run-time type information (and related methods).

const RegionType& itk::ImageReverseConstIterator< TImage >::GetRegion ( ) const [inline, inherited]

Get the region that this iterator walks. ImageReverseConstIterators know the beginning and the end of the region of the image to iterate over.

Definition at line 319 of file itkImageReverseConstIterator.h.

void itk::ImageRegionReverseConstIterator< TImage >::GoToBegin ( void ) [inline, inherited]

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

Reimplemented from itk::ImageReverseConstIterator< TImage >.

Definition at line 213 of file itkImageRegionReverseConstIterator.h.

void itk::ImageRegionReverseConstIterator< TImage >::GoToEnd ( void ) [inline, inherited]

Move an iterator to the end of the region. "End" for a reverse iterator is defined as one pixel before the first pixel in the region.

Reimplemented from itk::ImageReverseConstIterator< TImage >.

Definition at line 224 of file itkImageRegionReverseConstIterator.h.

bool itk::ImageReverseConstIterator< TImage >::IsAtBegin ( void ) [inline, inherited]

Is the iterator at the beginning of the (reverse) region? "Begin" for a reverse iterator is the last pixel in the region.

Definition at line 371 of file itkImageReverseConstIterator.h.

bool itk::ImageReverseConstIterator< TImage >::IsAtEnd ( void ) [inline, inherited]

Is the iterator at the end of the (reverse) region? "End" for a reverse iterator is one pixel before the first pixel in the region.

Definition at line 378 of file itkImageReverseConstIterator.h.

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

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

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

Definition at line 289 of file itkImageReverseConstIterator.h.

References itk::ImageReverseConstIterator< TImage >::m_Buffer, and itk::ImageReverseConstIterator< TImage >::m_Offset.

Self& itk::ImageRegionReverseConstIterator< TImage >::operator++ ( ) [inline, inherited]

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 266 of file itkImageRegionReverseConstIterator.h.

Self& itk::ImageRegionReverseConstIterator< TImage >::operator-- ( ) [inline, inherited]

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.

void itk::ImageRegionReverseConstIterator< TImage >::SetIndex ( const IndexType & ind ) [inline, inherited]

Set the index. No bounds checking is performed. This is overridden from the parent because we have an extra ivar.

Return a const reference to the pixel This method will provide the fastest access to pixel data, but it will NOT support ImageAdaptors.
