Detailed Description

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

Multi-dimensional image iterator.

ImageConstIteratorWithIndex is a templated class to represent a multi-dimensional iterator. ImageConstIteratorWithIndex is templated over the dimension of the image and the data type of the image.

ImageConstIteratorWithIndex is a base class for image iterators. It provides the basic construction and comparison operations. However, it does not provide mechanisms for moving the iterator. A subclass of ImageConstIteratorWithIndex must be used to move the iterator.

ImageConstIteratorWithIndex is a multi-dimensional iterator, requiring 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, ImageConstIteratorWithIndex holds a reference to the image over which it is traversing.

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

Constructor & Destructor Documentation

template<typename TImage>

itk::ImageConstIteratorWithIndex< TImage >::ImageConstIteratorWithIndex ( )

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

template<typename TImage>

itk::ImageConstIteratorWithIndex< TImage >::ImageConstIteratorWithIndex ( 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::ImageConstIteratorWithIndex< TImage >::ImageConstIteratorWithIndex ( const TImage * ptr,

const RegionType & region

)

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