Detailed Description

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

Multi-dimensional image iterator which only walks a region.

ImageRegionIterator is a templated class to represent a multi-dimensional iterator. ImageRegionIterator is templated over the image type ImageRegionIterator is constrained to walk only within the specified region and along a line parallel to one of the coordinate axis.

Most of the functionality is inherited from the ImageRegionConstIterator. The current class only adds write access to image pixels.

Member Typedef Documentation

template<typename TImage>
typedef Superclass::AccessorType itk::ImageRegionIterator< TImage >::AccessorType
 

Accessor type that convert data between internal and external representations.

Reimplemented from itk::ImageRegionConstIterator< TImage >.

Definition at line 65 of file itkImageRegionIterator.h.

template<typename TImage>
typedef Superclass::ImageType itk::ImageRegionIterator< TImage >::ImageType
 

Image typedef support. While this was already typdef'ed in the superclass it needs to be redone here for this subclass to compile properly with gcc.

Reimplemented from itk::ImageRegionConstIterator< TImage >.

template<typename TImage>
typedef Superclass::PixelContainer itk::ImageRegionIterator< TImage >::PixelContainer

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 ImageIteratorWithIndex< 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.

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator const ImageRegionConstIterator< TImage > &    it [protected]
 

the construction from a const iterator is declared protected in order to enforce const correctness.


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>
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>
Self& itk::ImageRegionIterator< TImage >::operator= const ImageRegionConstIterator< TImage > &    it [protected]
 

the construction from a const iterator is declared protected in order to enforce const correctness.

template<typename TImage>
void itk::ImageRegionIterator< TImage >::Set const PixelType   value const [inline]
 

Set the pixel value

template<typename TImage>
PixelType& itk::ImageRegionIterator< TImage >::Value void    [inline]
 

Return a reference to the pixel This method will provide the fastest access to pixel data, but it will NOT support ImageAdaptors.
