* Esta clase se encarga de la gesti?n del dibujado de datos le?dos desde la capa

85 |
* es un buffer (RasterBuffer) y un objeto que realice la funci?n de escritura de datos a
|
86 |
* partir de un estado inicial.
|
87 |
* Esta capa del renderizado gestiona Extents, rotaciones, tama?os de vista pero la escritura
|
88 |
* de datos desde el buffer al objeto image es llevada a cabo por ImageDrawer.

93 |
* <LI>replicateBands: Para visualizaci?n de raster de una banda. Dice si se replica sobre las otras dos bandas

* de visualizaci?n o se ponen a 0.</LI>
|
95 |
* <LI>enhanced: aplicaci?n de filtro de realce</LI>
|
96 |
* <LI>removeEnds: Eliminar extremos en el filtro de realce. Uso del segundo m?ximo y m?nimo</LI>
|
97 |
* <LI>tailTrim: Aplicacion de recorte de colas en el realce. Es un valor decimal que representa el porcentaje del recorte entre 100.
