* Class for the WCS layer.
|
| 115 |
*
|
| 116 |
* Capa para el WCS.
|
| 117 |
*
|
| 118 |
* Las capas WCS son tileadas para descargarlas del servidor. Esto quiere decir que
|
| 119 |
* est?n formadas por multiples ficheros raster. Por esto la fuente de datos raster (IRasterDatasource)
|
| 120 |
* de la capa FLyrWCS es un objeto de tipo CompositeDataset. Este objeto est? compuesto por un array
|
| 121 |
* bidimensional de MultiRasterDataset. Cada uno de los MultiRasterDataset corresponde con un tile
|
| 122 |
* salvado en disco. Estos MultiRasterDataset se crean cada vez que se repinta ya que en WCS a cada
|
| 123 |
* zoom varian los ficheros fuente. La secuencia de creaci?n de un CompositeDataset ser?a la siguiente:
|
| 124 |
* <UL>
|
| 125 |
* <LI>Se hace una petici?n de dibujado por parte del usuario llamando al m?todo draw de FLyrWCS</LI>
|
| 126 |
* <LI>Se tilea la petici?n</LI>
|
| 127 |
* <LI>Cada tile se dibuja abriendo una FLyrRaster para ese tile</LI>
|
| 128 |
* <LI>Si es el primer dibujado se guarda una referencia en la capa WMS a las propiedades de renderizado, orden de bandas,
|
| 129 |
* transparencia, filtros aplicados, ...</LI>
|
| 130 |
* <LI>Si no es el primer dibujado se asignan las propiedades de renderizado cuya referencia se guarda en la capa WMS</LI>
|
| 131 |
* <LI>Se guarda el MultiRasterDataset de cada tile</LI>
|
| 132 |
* <LI>Al acabar todos los tiles creamos un CompositeDataset con los MultiRasterDataset de todos los tiles</LI>
|
| 133 |
* <LI>Asignamos a la capa la referencia de las propiedades de renderizado que tenemos almacenadas. De esta forma si hay
|
| 134 |
* alguna modificaci?n desde el cuadro de propiedades ser? efectiva sobre los tiles que se dibujan.</LI>
|
| 135 |
* </UL>
