Detailed Description

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

Multi-dimensional image iterator which only walks a region.

ReflectiveImageRegionConstIterator is a templated class to represent a multi-dimensional iterator. ReflectiveImageRegionConstIterator is templated over the image type. ReflectiveImageRegionConstIterator is constrained to walk only within the specified region.

ReflectiveImageRegionConstIterator will perform two passes over the image along each dimension. It is useful for algorithms that require to go back and forth (once) over the data.

By setting the BeginOffset and EndOffset parameters, you can arrange for the starting point, when going forwards, to be different from the ending point, when going backwards. Along dimension d, when going forwards the iterator traverses the interval [BeginIndex[d]+BeginOffset[d], EndIndex[d]). When going back, it traverses the interval (EndIndex[d]-EndOffset[d], BeginIndex[d]]. Setting both offsets to (1, ..., 1) enables the DanielssonDistanceMapImageFilter to process the entire image, rather than removing a one-pixel border.

Member Typedef Documentation

template<typename TImage>

typedef TImage itk::ReflectiveImageRegionConstIterator< 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. Note that we have to rescope Image back to itk::Image to that is it not confused with ImageIterator::Image.

Reimplemented from itk::ImageConstIteratorWithIndex< TImage >.

Reimplemented in itk::ReflectiveImageRegionIterator< TImage >.

Constructor & Destructor Documentation

template<typename TImage>

itk::ReflectiveImageRegionConstIterator< TImage >::ReflectiveImageRegionConstIterator ( )

Default constructor. Needed since we provide a cast constructor.

template<typename TImage>

itk::ReflectiveImageRegionConstIterator< TImage >::~ReflectiveImageRegionConstIterator ( )

inline

Default destructor.

Definition at line 96 of file itkReflectiveImageRegionConstIterator.h.

template<typename TImage>

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

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

Member Function Documentation

template<typename TImage>

void itk::ReflectiveImageRegionConstIterator< TImage >::FillOffsets ( const OffsetValueType & value )

Fill both offsets with a single value.

template<typename TImage>

OffsetType itk::ReflectiveImageRegionConstIterator< TImage >::GetBeginOffset ( const OffsetType & )

inline

Get the begin offset. Forward iteration starts at this offset from the current region.

Definition at line 151 of file itkReflectiveImageRegionConstIterator.h.

template<typename TImage>

OffsetType itk::ReflectiveImageRegionConstIterator< TImage >::GetEndOffset ( const OffsetType & )

inline

Get the end offset. Reverse iteration starts at this offset from the current region.

Definition at line 156 of file itkReflectiveImageRegionConstIterator.h.

template<typename TImage>

void itk::ReflectiveImageRegionConstIterator< TImage >::GoToBegin ( void )

Move an iterator to the beginning of the region.

Reimplemented from itk::ImageConstIteratorWithIndex< TImage >.

template<typename TImage>

bool itk::ReflectiveImageRegionConstIterator< TImage >::IsAtBegin ( void ) const

inline

Is the iterator at the beginning of the region?

Definition at line 134 of file itkReflectiveImageRegionConstIterator.h.

template<typename TImage>

bool itk::ReflectiveImageRegionConstIterator< TImage >::IsReflected ( unsigned int ) const

template<typename TImage>

Self& itk::ReflectiveImageRegionConstIterator< TImage >::operator++ ( )

Increment (prefix) the fastest moving dimension of the iterator's index. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the end of the row of the region to the beginning of the next row of the region) up until the iterator tries to moves past the last pixel of the region. Here, the iterator will be set to be one pixel past the end of the region.
