15 | * 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.
