Constructor & Destructor Documentation

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator  ) 
 

Default constructor. Needed since we provide a cast constructor.

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator ImageType ptr,
const RegionType region
 

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

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator const ImageIterator< TImage > &  it  ) 
 

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

Member Function Documentation

template<typename TImage>
Self itk::ImageRegionIterator< TImage >::Begin void   )  const
 

Return an iterator for the beginning of the region. "Begin" is defined as the first pixel in the region.

Deprecated:
Use GoToBegin() instead

Reimplemented from itk::ImageRegionConstIterator< TImage >.

template<typename TImage>
itk::ImageRegionConstIterator< TImage >::Decrement prefix   )  const [inherited]
 

template<typename TImage>
Self itk::ImageRegionIterator< TImage >::End void   )  const
 

Return an iterator for the end of the region. "End" is defined as one pixel past the last pixel of the region.

Deprecated:
Use GoToEnd() instead

Reimplemented from itk::ImageRegionConstIterator< TImage >.

template<typename TImage>
PixelType itk::ImageConstIterator< TImage >::Get void   )  const [inline, inherited]
 

Get the pixel value

Definition at line 316 of file itkImageConstIterator.h.

template<typename TImage>
const ImageType* itk::ImageConstIterator< TImage >::GetImage  )  const [inline, inherited]
 

Get the image that this iterator walks.

Reimplemented in itk::ImageIterator< TImage >.

Definition at line 312 of file itkImageConstIterator.h.

template<typename TImage>
static unsigned int itk::ImageConstIterator< TImage >::GetImageIteratorDimension  )  [inline, static, inherited]
 

Get the dimension (size) of the index.

Definition at line 227 of file itkImageConstIterator.h.

template<typename TImage>
const IndexType itk::ImageConstIterator< TImage >::GetIndex void   )  const [inline, inherited]
 

Get the index. This provides a read only reference to the index. This causes the index to be calculated from pointer arithmetic and is therefore an expensive operation.

See also:
SetIndex

Definition at line 298 of file itkImageConstIterator.h.

template<typename TImage>
virtual const char* itk::ImageRegionConstIterator< TImage >::GetNameOfClass  )  const [virtual, inherited]
 

Run-time type information (and related methods).

template<typename TImage>
const RegionType& itk::ImageConstIterator< TImage >::GetRegion  )  const [inline, inherited]
 

Get the region that this iterator walks. ImageConstIterators know the beginning and the end of the region of the image to iterate over.

Definition at line 308 of file itkImageConstIterator.h.

template<typename TImage>
void itk::ImageRegionConstIterator< TImage >::GoToBegin void   )  [inline, inherited]
 

Move an iterator to the beginning of the region. "Begin" is defined as the first pixel in the region.

Reimplemented from itk::ImageConstIterator< TImage >.

Definition at line 210 of file itkImageRegionConstIterator.h.

template<typename TImage>
void itk::ImageRegionConstIterator< TImage >::GoToEnd void   )  [inline, inherited]
 

Move an iterator to the end of the region. "End" is defined as one pixel past the last pixel of the region.

template<typename TImage>
bool itk::ImageConstIterator< TImage >::IsAtBegin void   )  const [inline, inherited]
 

Is the iterator at the beginning of the region? "Begin" is defined as the first pixel in the region.

Definition at line 353 of file itkImageConstIterator.h.

template<typename TImage>
bool itk::ImageConstIterator< TImage >::IsAtEnd void   )  const [inline, inherited]
 

Is the iterator at the end of the region? "End" is defined as one pixel past the last pixel of the region.

template<typename TImage>
itk::ImageConstIterator< TImage >::itkStaticConstMacro ImageIteratorDimension  ,
unsigned  int,
TImage::ImageDimension

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.
