|
* \brief Give access to partial aspects a type |
| 28 |
|
* |
| 29 |
|
* DefaultPixelAccessor is templated over an internal type and an |
| 30 |
|
* external type representation. This class encapsulates a |
| 31 |
|
* customized convertion between the internal and external |
| 32 |
|
* type representations. |
| 33 |
|
* |
| 34 |
|
* PixelAccessor is the class responsible for pixel-to-pixel |
| 35 |
|
* transformation during image data access. The DefaultPixelAccessor |
| 36 |
|
* is an identity operation on the pixel value. It only exist in |
| 37 |
|
* order to standarize the way in which pixels are accessed. |
| 38 |
|
* |
| 39 |
|
* PixelAccessor are used by ImageAdaptors in order to present |
| 40 |
|
* an Image as being of a different type. The usual application |
| 41 |
|
* of ImageAccessors is Image casting, by avoiding the overhead |
| 42 |
|
* of an ImageFilter that performs the complete transformation |
