Detailed Description

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

Multi-dimensional image iterator which only walks a region.

ReflectiveImageRegionConstIterator is a templated class to represent a multi-dimensional iterator. ReflectiveImageRegionConstIterator is templated over the image type. ReflectiveImageRegionConstIterator is constrained to walk only within the specified region.

ReflectiveImageRegionConstIterator will perform two passes over the image along each dimension. It is useful for algorithms that require to go back and forth (once) over the data.

By setting the BeginOffset and EndOffset parameters, you can arrange for the starting point, when going forwards, to be different from the ending point, when going backwards. Along dimension d, when going forwards the iterator traverses the interval [BeginIndex[d]+BeginOffset[d], EndIndex[d]). When going back, it traverses the interval (EndIndex[d]-EndOffset[d], BeginIndex[d]]. Setting both offsets to (1, ..., 1) enables the DanielssonDistanceMapImageFilter to process the entire image, rather than removing a one-pixel border.

Constructor & Destructor Documentation

Default constructor. Needed since we provide a cast constructor.

template<typename TImage>
itk::ReflectiveImageRegionConstIterator< TImage >::~ReflectiveImageRegionConstIterator (  )  [inline]

Default destructor.

Definition at line 94 of file itkReflectiveImageRegionConstIterator.h.

template<typename TImage>
itk::ReflectiveImageRegionConstIterator< TImage >::ReflectiveImageRegionConstIterator ( 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::ReflectiveImageRegionConstIterator< TImage >::ReflectiveImageRegionConstIterator ( 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::ReflectiveImageRegionConstIterator< TImage >::ReflectiveImageRegionConstIterator ( const ImageConstIteratorWithIndex< TImage > &  it  ) 

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

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.

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.
