Detailed Description

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

A multi-dimensional iterator templated over image type that walks pixels within a region and is specialized to keep track of its image index location.

This class is a specialization of ImageRegionConstIteratorWithIndex that adds write-access (the Set() method). Please see ImageRegionConstIteratorWithIndex for more information.

Constructor & Destructor Documentation

template<typename TImage>

itk::ImageRegionIteratorWithIndex< TImage >::ImageRegionIteratorWithIndex ( )

default

Default constructor. Needed since we provide a cast constructor.

template<typename TImage>

itk::ImageRegionIteratorWithIndex< TImage >::ImageRegionIteratorWithIndex	(	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::ImageRegionIteratorWithIndex< TImage >::ImageRegionIteratorWithIndex

(

const ImageIteratorWithIndex< TImage > &

it

)

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

template<typename TImage>

itk::ImageRegionIteratorWithIndex< TImage >::ImageRegionIteratorWithIndex ( const ImageRegionConstIteratorWithIndex< 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::ImageRegionIteratorWithIndex< TImage >::operator= ( const ImageRegionConstIteratorWithIndex< TImage > &  it )

protected

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

template<typename TImage>

void itk::ImageRegionIteratorWithIndex< TImage >::Set ( const PixelType &  value ) const

inline

Set the pixel value

Definition at line 106 of file itkImageRegionIteratorWithIndex.h.

template<typename TImage>

PixelType& itk::ImageRegionIteratorWithIndex< TImage >::Value ( )

inline

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