itk::LineIterator< TImage > Class Template Reference

#include <itkLineIterator.h>

Detailed Description

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

An iterator that walks a Bresenham line through an ND image with write access to pixels.

LineIterator is an iterator that walks a Bresenham line through an image. The iterator is constructed similar to other image iterators, except instead of specifying a region to traverse, you specify two indices. The interval specified by the two indices is closed. So, a line iterator specified with the same start and end index will visit exactly one pixel.

LineConstIterator<ImageType> it(image, I1, I2);
while (!it.IsAtEnd())
{
// visits at least 1 pixel
}

Member Typedef Documentation

◆ AccessorType

template<typename TImage>
using itk::LineConstIterator< TImage >::AccessorType = typename TImage::AccessorType

Accessor type that convert data between internal and external representations.

Definition at line 104 of file itkLineConstIterator.h.

◆ ImageType

template<typename TImage>
using itk::LineConstIterator< TImage >::ImageType = TImage

Image type alias support

Definition at line 88 of file itkLineConstIterator.h.

◆ IndexType

template<typename TImage>
using itk::LineConstIterator< TImage >::IndexType = typename TImage::IndexType

Index type alias support

Definition at line 70 of file itkLineConstIterator.h.

◆ InternalPixelType

template<typename TImage>
using itk::LineConstIterator< TImage >::InternalPixelType = typename TImage::InternalPixelType

Internal Pixel Type

Definition at line 97 of file itkLineConstIterator.h.

◆ OffsetType

template<typename TImage>
using itk::LineConstIterator< TImage >::OffsetType = typename TImage::OffsetType

Offset type alias support

Definition at line 73 of file itkLineConstIterator.h.

◆ PixelContainer

template<typename TImage>
using itk::LineConstIterator< TImage >::PixelContainer = typename TImage::PixelContainer

PixelContainer type alias support Used to refer to the container for the pixel data. While this was already typedef'ed in the superclass, it needs to be redone here for this subclass to compile properly with gcc.

Definition at line 93 of file itkLineConstIterator.h.

◆ PixelContainerPointer

template<typename TImage>
using itk::LineConstIterator< TImage >::PixelContainerPointer = typename PixelContainer::Pointer

Definition at line 94 of file itkLineConstIterator.h.

◆ PixelType

template<typename TImage>
using itk::LineConstIterator< TImage >::PixelType = typename TImage::PixelType

External Pixel Type

Definition at line 100 of file itkLineConstIterator.h.

◆ RegionType

template<typename TImage>
using itk::LineConstIterator< TImage >::RegionType = typename TImage::RegionType

Region type alias support

Definition at line 79 of file itkLineConstIterator.h.

◆ Self

template<typename TImage>
using itk::LineIterator< TImage >::Self = LineIterator

Standard class type aliases.

Definition at line 61 of file itkLineIterator.h.

◆ SizeType

template<typename TImage>
using itk::LineConstIterator< TImage >::SizeType = typename TImage::SizeType

Constructor & Destructor Documentation

◆ LineIterator()

template<typename TImage>
itk::LineIterator< TImage >::LineIterator ( ImageType imagePtr,
const IndexType firstIndex,
const IndexType lastIndex 
)

Constructor establishes an iterator to walk along a path

◆ ~LineIterator()

template<typename TImage>
itk::LineIterator< TImage >::~LineIterator ( )
overridedefault

Default Destructor.

Member Function Documentation

◆ GetNameOfClass()

template<typename TImage>
const char* itk::LineIterator< TImage >::GetNameOfClass ( ) const
overridevirtual

◆ operator=()

template<typename TImage>
Self& itk::LineIterator< TImage >::operator= ( const Self it)

operator= is provided to make sure the handle to the image is properly reference counted.

◆ Set()

template<typename TImage>
void itk::LineIterator< TImage >::Set ( const PixelType value)
inline

Set the pixel value

Definition at line 89 of file itkLineIterator.h.

◆ Value()

template<typename TImage>
const PixelType& itk::LineIterator< 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.

Definition at line 103 of file itkLineIterator.h.

Member Data Documentation

◆ ImageIteratorDimension

template<typename TImage>
constexpr unsigned int itk::LineIterator< TImage >::ImageIteratorDimension = TImage::ImageDimension
staticconstexpr

Dimension of the image that the iterator walks. This constant is needed so that 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.

Definition at line 67 of file itkLineIterator.h.
