itk::ImageScanlineIterator< TImage > Class Template Reference

#include <itkImageScanlineIterator.h>

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.

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

Image type alias support

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 ( TImage *  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.
