* Esta clase contiene informaci?n de transparencia de un objeto. Los objetos
|
| 43 |
* pueden ser dataset, grid u otros. Cuando un usuario quiere a?adir nueva
|
| 44 |
* informaci?n de transparencia crea un objeto de este tipo que debe ser
|
| 45 |
* mezclado (merge) con otros objetos de este tipo que existan para la misma
|
| 46 |
* fuente de datos.
|
| 47 |
* </p>
|
| 48 |
* <p>
|
| 49 |
* Un multirasterdatset obtiene los distintos objetos transparency de todos los
|
| 50 |
* ficheros que los componen. Para realizar un solo objeto transparency se har?
|
| 51 |
* un merge de todos ellos.
|
| 52 |
* </p>
|
| 53 |
* <p>
|
| 54 |
* Finalmente y antes de renderizar se necesita un objeto Transparency. Este
|
| 55 |
* estar? compuesto con toda la informaci?n de transparencia aplicar, es decir,
|
| 56 |
* todos los objetos Transparency mezclados.Transparency con tiene el
|
| 57 |
* m?todo de procesado de un pixel. Se le proporciona un pixel y devuelve este
|
| 58 |
* mismo pixel con la transparencia aplicada.
|
| 59 |
* </p>
|
| 60 |
* <p>
|
| 61 |
* Una transparencia que se aplica a un buffer puede tener cuatro procedencias distintas:
|
| 62 |
* <UL>
|
| 63 |
* <LI>Mascara: Un buffer de NxN aplicado sobre la zona a renderizar como una m?scara de
|
| 64 |
* transparencia. Las bandas alpha de las imagenes se comportan de esta forma.</LI>
|
| 65 |
* <LI>Opacidad global: Un valor de opacidad se aplicado a cada pixel a renderizar. Este es
|
| 66 |
* igual para todos los p?xeles.</LI>
|
| 67 |
* <LI>Rangos: Una lista de rangos de valores RGB. Cada pixel cuyo valor est? dentro de alguno
|
| 68 |
* de los rangos se aplica como transparente.</LI>
|
| 69 |
* <LI>Dato: Todos los valores del buffer que coincidan con ese dato son puestos como transparente.
|
| 70 |
* Para que esto sea posible tenemos que disponer del buffer de datos originales sin ning?n proceso.</LI>
|
| 71 |
* </UL>
