Detailed Description

clase base para el manejo de una textura con su copia comprimida en memoria

Esta clase mantiene en memoria una copia comprimida de la imagen a medida que esta imagen es requerida se aumenta el numero de referencia cuando la cantidad de referencias llegan a cero se da de baja de la memoria de opengl

just execute this time for building the texture really in card memory

then apply the buffer

int moTextureMemory::GetReference

(

)

Devuelve una referencia (internamente marca la referencia y asigna la imagen a la textura) Para liberar la memoria de opengl hay q desreferenciar...

Returns

la cantidad de referencias (si es 0 es que no pudo cargar nada, asi q la referencia no sirve)

Definition at line 1319 of file moTexture.cpp.

MOboolean moTextureMemory::Init ( moText  p_name, MOuint  p_moid, moResourceManager *  p_res, moTexParam  p_param = MODefTex2DParams  )

virtual

Inicializa propiedades básicas de la textura tales como el nombre, id, administradores y parámetros.

Parameters

p_name	nombre de la textura.
p_moid	Moldeo ID de la textura.
p_res	puntero al administrador de recursos, del cual son extraidos todos los administradores que la textura necesita (GL, Data, File, etc).
p_param	parámetros de textura.

Returns

true si la operación fue exitosa, false en caso contrario.

Reimplemented from moTexture.

if there were already something , delete it! size may be different now!!!

close memory

Calculate luminance and contrast from histogram

calculate luminance

Calculating contrast difference or luminance variance
