* Driver para la compresi?n en formato Ecw.
|
| 16 |
*
|
| 17 |
* Puede exportar un fichero desde un GeoRasterFile en cualquier formato soportado
|
| 18 |
* por los drivers de lectura a uno en formato Ecw.
|
| 19 |
*
|
| 20 |
* Puede salvar a disco en formato Ecw obteniendo los datos que van siendo servidos
|
| 21 |
* desde el cliente. Este cliente debe implementar un IDataWriter o tener un objeto
|
| 22 |
* que lo implemente. Inicialmente le pasar? los par?metros de la imagen de salida
|
| 23 |
* y cuando el driver comience a escribir le ir? solicitando m?s a trav?s del m?todo
|
| 24 |
* readData de IDataWriter. El cliente ser? el que lleve el control de lo que va
|
| 25 |
* sirviendo y lo que le queda por servir.
