Detailed Description

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

A multi-dimensional iterator templated over image type.

This is a base class of ImageConstIterator that adds write-access functionality. Please see ImageConstIterator for more information.

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.

Constructor & Destructor Documentation

template<typename TImage>

itk::ImageIterator< TImage >::ImageIterator ( )

Default Constructor. Need to provide a default constructor since we provide a copy constructor.

template<typename TImage>

itk::ImageIterator< TImage >::~ImageIterator ( ) [inline]

Default Destructor

Definition at line 101 of file itkImageIterator.h.

template<typename TImage>

itk::ImageIterator< TImage >::ImageIterator ( const Self & it )

Copy Constructor. The copy constructor is provided to make sure the handle to the image is properly reference counted.

template<typename TImage>

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

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

template<typename TImage>

itk::ImageIterator< TImage >::ImageIterator ( const ImageConstIterator< TImage > & it ) [protected]

This constructor is declared protected in order to enforce const-correctness

Member Function Documentation

template<typename TImage>

Self itk::ImageIterator< 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::ImageConstIterator< TImage >.

template<typename TImage>

Self itk::ImageIterator< 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::ImageConstIterator< TImage >.

template<typename TImage>

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

Get the pixel value

Definition at line 326 of file itkImageConstIterator.h.

Definition at line 146 of file itkImageIterator.h.

template<typename TImage>

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

Definition at line 237 of file itkImageConstIterator.h.

template<typename TImage>

const IndexType itk::ImageConstIterator< TImage >::GetIndex ( void ) const [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.

Member Data Documentation

template<typename TImage>

const unsigned int itk::ImageIterator< TImage >::ImageIteratorDimension = TImage::ImageDimension [static]

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.
