* \class ImageIteratorWithIndex |
| 27 |
|
* \brief A base class for multi-dimensional iterators templated over image |
| 28 |
|
* type that are designed to efficiently keep track of the iterator |
| 29 |
|
* position. |
| 30 |
|
* |
| 31 |
|
* This class inherits from ImageConstIteratorWithIndex and only adds |
| 32 |
|
* write-access functionality. See ImageConstIteratorWithIndex for more |
| 33 |
|
* information. |
