Detailed Description

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

Multi-dimensional image iterator that walks an image region, excluding a second region contained within the first.

ImageRegionExclusionConstIteratorWithIndex is a templated class to represent a multi-dimensional iterator. ImageRegionExclusionConstIteratorWithIndex is templated over the image type. ImageRegionExclusionConstIteratorWithIndex is constrained to walk only within the specified region. The exclusion region is set after construction. By default the exclusion region is empty and the iterator will behave as the itk::ImageRegionIteratorWithIndex with a penalty in performance due to internal bounds checking.

As with other ITK image iterators, ImageRegionExclusionConstIteratorWithIndex requires more information be specified before the iterator can be used than conventional iterators. Whereas the std::vector::iterator from the STL only needs to be passed a pointer to establish the iterator, the multi-dimensional image iterator needs a pointer, the size of the buffer, the size of the region, the start index of the buffer, and the start index of the region. To gain access to this information, ImageRegionExclusionConstIteratorWithIndex holds a reference to the image over which it is traversing.

ImageRegionExclusionConstIteratorWithIndex assumes a particular layout of the image data. The is arranged in a 1D array as if it were [][][][slice][row][col] with Index[0] = col, Index[1] = row, Index[2] = slice, etc.

The operator++ method provides a simple syntax for walking around a region of a multidimensional image. operator++ iterates across a row, constraining the movement to within a region of image. When the iterator reaches the boundary of the region along a row, the iterator automatically wraps to the next row, starting at the first pixel in the row that is part of the region. This allows for simple processing loops of the form:

Constructor & Destructor Documentation

Default constructor. Needed since we provide a cast constructor.

Definition at line 158 of file itkImageRegionExclusionConstIteratorWithIndex.h.

template<typename TImage>
itk::ImageRegionExclusionConstIteratorWithIndex< TImage >::ImageRegionExclusionConstIteratorWithIndex ( const TImage *  ptr,
const RegionType region 
) [inline]

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

Definition at line 162 of file itkImageRegionExclusionConstIteratorWithIndex.h.

template<typename TImage>
itk::ImageRegionExclusionConstIteratorWithIndex< TImage >::ImageRegionExclusionConstIteratorWithIndex ( const ImageConstIteratorWithIndex< TImage > &  it  )  [inline]

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

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::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::ImageRegionExclusionConstIteratorWithIndex< TImage >::operator++ (  ) 

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.

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 next 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.

template<typename TImage>
void itk::ImageRegionExclusionConstIteratorWithIndex< TImage >::SetExclusionRegionToInsetRegion (  ) 

Set the exclusion region to be inset one pixel in from the region the iterator walks. This configures the iterator to only walk the pixels on the boundary of the region.
