itk::ImageRegionIterator< TImage > Class Template Reference
#include <itkImageRegionIterator.h>
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
| itk::ImageRegionIterator< TImage >::ImageRegionIterator | ( | ) |
Default constructor. Needed since we provide a cast constructor.
| 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.
| 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.
| 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

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

| Self itk::ImageRegionIterator< TImage >::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.

| Self& itk::ImageRegionConstIterator< TImage >::operator++ | ( | ) | [inline, inherited] |
Increment (prefix) the fastest moving dimension of the iterator's index. This operator will constrain the iterator within the region (i.e. the iterator will automatically wrap from the end of the row of the region to the beginning of the next row of the region) up until the iterator tries to moves past the last pixel of the region. Here, the iterator will be set to be one pixel past the end of the region.
