itk::ImageSliceConstIteratorWithIndex< TImage > Class Template Reference

#include <itkImageSliceConstIteratorWithIndex.h>

Detailed Description

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

Multi-dimensional image iterator which only walks a region.

A multi-dimensional image iterator that extends the ImageLinearConstIteratorWithIndex from iteration along lines in an image to iteration along both lines and planes (slices) within an image. A slice is defined as a 2D plane spanned by two vectors pointing along orthogonal coordinate axes. The slice orientation of the iterator is defined by specifying its two spanning axes using the methods:

SetFirstDirection(n)
SetSecondDirection(n)

where n is the number of the axis.

Use the following methods to move the iterator between slices:

NextSlice()
PreviousSlice()

To test the position of the iterator with respect to the end or beginning of the slice use the following methods:

IsAtReverseEndOfSlice()
IsAtEndOfSlice()

The following code, for example, illustrates the typical use of this iterator. For more information please see the Software Guide.

ImageSliceConstIteratorWithIndex<ImageType> it( image, image->GetRequestedRegion() );
 
it.SetFirstDirection(2);
it.SetSecondDirection(0);
 
it.GoToBegin();
while( !it.IsAtEnd() )
{
  while( !it.IsAtEndOfSlice() )
  {
    while( !it.IsAtEndOfLine() )
    {
       value = it.Get();  // it.Set() doesn't exist in the Const Iterator
       ++it;
    }
    it.NextLine();
  }
  it.NextSlice();
 }

Constructor & Destructor Documentation

ImageSliceConstIteratorWithIndex() [1/3]

template<typename TImage>

itk::ImageSliceConstIteratorWithIndex< TImage >::ImageSliceConstIteratorWithIndex ( )

inline

Default constructor. Needed since we provide a cast constructor.

Definition at line 133 of file itkImageSliceConstIteratorWithIndex.h.

ImageSliceConstIteratorWithIndex() [2/3]

template<typename TImage>

itk::ImageSliceConstIteratorWithIndex< TImage >::ImageSliceConstIteratorWithIndex ( const ImageType *  ptr, const RegionType &  region  )

inline

Constructor establishes an iterator to walk a particular image and a particular region of that image. Initializes the iterator at the begin of the region.

Definition at line 139 of file itkImageSliceConstIteratorWithIndex.h.

ImageSliceConstIteratorWithIndex() [3/3]

template<typename TImage>

itk::ImageSliceConstIteratorWithIndex< TImage >::ImageSliceConstIteratorWithIndex ( const ImageConstIteratorWithIndex< TImage > &  it )

inline

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