Detailed Description

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

A multi-dimensional iterator templated over image type that walks a region of pixels.

The itk::ImageRegionIterator is optimized for iteration speed and is the first choice for iterative, pixel-wise operations on an image. ImageRegionIterator is the least specialized of the ITK image iterator classes. ImageRegionIterator is templated over the image type, and is constrained to walk only within the specified region and along a line parallel to one of the coordinate axes, "wrapping" to the next line as it reaches the boundary of the image. To walk the entire image, specify the region to be image->GetRequestedRegion().

Most of the functionality is inherited from the ImageRegionConstIterator. The current class only adds write access to image pixels.

Constructor & Destructor Documentation

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator ( )

Default constructor. Needed since we provide a cast constructor.

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

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

template<typename TImage>
itk::ImageRegionIterator< TImage >::ImageRegionIterator ( const ImageRegionConstIterator< TImage > &  it)
protected

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

Member Function Documentation

template<typename TImage>
itk::ImageRegionIterator< TImage >::itkLegacyMacro ( Self Begin(void)  const)

Return an iterator for the beginning of the region. "Begin" is defined as the first pixel in the region.

Deprecated:
Use GoToBegin() instead
template<typename TImage>
itk::ImageRegionIterator< TImage >::itkLegacyMacro ( Self End(void)  const)

Return an iterator for the end of the region. "End" is defined as one pixel past the last pixel of the region.

Deprecated:
Use GoToEnd() instead
template<typename TImage>
Self& itk::ImageRegionIterator< TImage >::operator= ( const ImageRegionConstIterator< TImage > &  it)
protected

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

template<typename TImage>
void itk::ImageRegionIterator< TImage >::Set ( const PixelType value) const
inline
template<typename TImage>
PixelType& itk::ImageRegionIterator< TImage >::Value ( void  )
inline

Return a reference to the pixel This method will provide the fastest access to pixel data, but it will NOT support ImageAdaptors.
