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.

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::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.

Is the iterator at the beginning of the region?

Definition at line 265 of file itkImageConstIteratorWithIndex.h.

template<typename TImage>
itk::ImageConstIteratorWithIndex< TImage >::itkStaticConstMacro ImageDimension  ,
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.

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.
