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.

Constructor & Destructor Documentation

template<typename TImage>

itk::ImageScanlineIterator< TImage >::ImageScanlineIterator

(

)

Default constructor. Needed since we provide a cast constructor.

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.

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.

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.
