Detailed Description

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

A multi-dimensional iterator templated over image type that walks a region of pixels, scanline by scanline or in the direction of the fastest axis.

The itk::ImageScanlineIterator is optimized for iteration speed and is the first choice for pixel-wise operations on an image. This iterator is preferred over the older ImageRegionIterator even when knowledge of the current line state is not desired because of its speed.

Member Typedef Documentation

◆ AccessorType

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

Accessor type that convert data between internal and external representations.

Definition at line 128 of file itkImageConstIterator.h.

◆ ImageType

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

Image type alias support

Definition at line 112 of file itkImageConstIterator.h.

◆ IndexType

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

Index type alias support

Definition at line 100 of file itkImageConstIterator.h.

◆ InternalPixelType

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

Definition at line 121 of file itkImageConstIterator.h.

◆ OffsetType

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

Offset type alias support

Definition at line 106 of file itkImageConstIterator.h.

◆ PixelContainer

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

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

using itk::ImageConstIterator< TImage >::PixelType = typename TImage::PixelType

External Pixel Type

Definition at line 124 of file itkImageConstIterator.h.

◆ RegionType

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

Region type alias support

Definition at line 109 of file itkImageConstIterator.h.

◆ Self

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

Standard class type aliases.

Definition at line 46 of file itkImageScanlineIterator.h.

◆ SizeType

template<typename TImage >

Constructor & Destructor Documentation

◆ ImageScanlineIterator() [1/4]

template<typename TImage >
itk::ImageScanlineIterator< TImage >::ImageScanlineIterator ( )
default

Default constructor. Needed since we provide a cast constructor.

◆ ImageScanlineIterator() [2/4]

template<typename TImage >
itk::ImageScanlineIterator< TImage >::ImageScanlineIterator ( ImageType ptr,
const RegionType region 
)

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

◆ ImageScanlineIterator() [3/4]

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

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

◆ ImageScanlineIterator() [4/4]

template<typename TImage >
itk::ImageScanlineIterator< TImage >::ImageScanlineIterator ( const ImageScanlineConstIterator< TImage > &  it)
protected

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

Member Function Documentation

◆ operator=()

template<typename TImage >
Self& itk::ImageScanlineIterator< TImage >::operator= ( const ImageScanlineConstIterator< TImage > &  it)
protected

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

◆ Set()

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

Set the pixel value

Definition at line 78 of file itkImageScanlineIterator.h.

◆ Value()

template<typename TImage >
PixelType& itk::ImageScanlineIterator< 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.
