/** \class ImageRegionReverseIterator |
| 27 |
|
* \brief Multi-dimensional image iterator which only walks a region. |
| 28 |
|
* |
| 29 |
LEN |
* ImageRegionReverseIterator is a templated class to represent a multi-dimensional |
| 30 |
|
* iterator. ImageRegionReverseIterator is templated over the image type |
| 31 |
|
* ImageRegionReverseIterator is constrained to walk only within the |
| 32 |
|
* specified region and along a line parallel to one of the coordinate axis. |
| 33 |
|
* |
| 34 |
LEN |
* Most of the functionality is inherited from the ImageRegionReverseConstIterator. |
| 35 |
|
* The current class only adds write access to image pixels. |
| 36 |
|
* |
| 37 |
|
* \par MORE INFORMATION |
| 38 |
|
* For a complete description of the ITK Image Iterators and their API, please |
| 39 |
|
* see the Iterators chapter in the ITK Software Guide. The ITK Software Guide |
| 40 |
|
* is available in print and as a free .pdf download from http://www.itk.org. |
