Detailed Description

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

A multi-dimensional iterator templated over image type that walks pixels within a region and is specialized to keep track of its image index location.

This class is a specialization of ImageRegionConstIteratorWithIndex that adds write-access (the Set() method). Please see ImageRegionConstIteratorWithIndex for more information.

Constructor & Destructor Documentation

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

Default constructor. Needed since we provide a cast constructor.

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

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

template<typename TImage >
itk::ImageRegionIteratorWithIndex< TImage >::ImageRegionIteratorWithIndex ( const ImageRegionConstIteratorWithIndex< TImage > &  it  )  [protected]

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

Definition at line 261 of file itkImageConstIteratorWithIndex.h.

template<typename TImage>
bool itk::ImageConstIteratorWithIndex< 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 162 of file itkImageConstIteratorWithIndex.h.

template<typename TImage>
Self& itk::ImageRegionConstIteratorWithIndex< 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.

operator--
template<typename TImage>
Self& itk::ImageRegionConstIteratorWithIndex< TImage >::operator-- (  )  [inherited]

Decrement (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 beginning of the row of the region to the end of the previous row of the region) up until the iterator tries to moves past the first pixel of the region. Here, the iterator will be set to be one pixel past the beginning of the region.

Member Data Documentation

template<typename TImage>
const unsigned int itk::ImageConstIteratorWithIndex< TImage >::ImageDimension = TImage::ImageDimension [static, 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.
