* Carga el buffer con las bandas RGB del raster con los par?metros especificados de extensi?n
|
412 |
* y tama?o de buffer. El problema de ecw es que solo podemos leer 3 bandas de una vez ya que solo disponemos
|
413 |
* de una llamada readLineRGBA. Para leer m?s bandas tendremos que hacer multiples llamadas a setView para leer
|
414 |
* 3 cada vez.
|
415 |
*
|
416 |
* Si por ejemplo tenemos un ecw de 6 bandas [0, 1, 2, 3, 4, 5] y queremos cargar un buffer con el siguiente orden
|
417 |
* [0, -, 2, -, 4, -] La variable readBandsFromECW har? la llamada a setView con los valores [0, 2, 4, 0, 0, 0]. La
|
418 |
* funci?n drawRGB ser? la encargada de hacer el switch para obtener [0, -, 2, -, 4, -].
|
419 |
*
|
420 |
* Bug#1: Si se dispone de un ecw de m?s de tres bandas podemos llamar a setView con readBandsFromECW con el orden
|
421 |
* que queramos, por ejemplo [3, 2, 5, 1, 0] pero para ecw de 3 bandas la llamada con las bandas cambiadas no
|
422 |
* hace caso. El caso de readBandsFromECW = [2, 0, 1] ser? tomado siempre como [0, 1, 2].
