createBuffer

Buffer createBuffer(int dataType,
                    int width,
                    int height,
                    int bandNr,
                    boolean malloc)

Deprecated. Use BufferFactory to get a BufferParams and build a Buffer BufferParam params = RasterManager.getBufferFactory().createBufferParams(dataType, width, height, bandNr, malloc); Buffer buffer = RasterManager.getBufferFactory().createBuffer(params);

Genera instancias del buffer de datos adecuado al tamaño del raster. Si no hay muchos datos (menos de cacheMemorySize) creará un buffer en memoria. Si hay más de esta cantidad entonces crearemos un buffer cacheado (RasterCache). A partir de la cantidad señalada por multicacheMemorySize haremos un buffer cacheado donde cada página no ocupa todo el ancho del raster ya que este será muy grande. La gestión de una cache donde cada pagina ha de partir una línea lleva una complejidad añadida.

Parameters:

dataType - Tipo de dato

width - Ancho

height - Alto

bandNr - Banda

flag - En caso de buffers de memoria este flag a true significa que se reserva la memoria para el buffer de forma normal y si está a false no se reserva por lo que la reserva deberá ser posterior.

Returns:

Objeto RasterBuffer

Throws:

RasterDriverException

NotSupportedExtensionException

FileNotFoundException

createMemoryBuffer

Buffer createMemoryBuffer(int dataType,
                          int width,
                          int height,
                          int bandNr,
                          boolean malloc)

Deprecated. Use BufferFactory to get a BufferParams and build a Buffer BufferParam params = RasterManager.getBufferFactory().createMemoryBufferParams(dataType, width, height, bandNr, malloc); Buffer buffer = RasterManager.getBufferFactory().createBuffer(params);

Genera una instancia del buffer de solo lectura. Este buffer consta de una cache y unos apuntadores a las páginas en disco. Cuando se accede a los datos se carga en memoria la página pedida.

Parameters:

dataType - Tipo de dato

width - Ancho

height - Alto

bandNr - Banda

flag - En caso de buffers de memoria este flag a true significa que se reserva la memoria para el buffer de forma normal y si está a false no se reserva por lo que la reserva deberá ser posterior.
