Imágenes divididas en bloques
Una imagen grande podría no caber en la memoria disponible y, por lo tanto, ser difícil de mostrar y procesar. El objeto blockedImage
ofrece una solución al problema: representa una imagen como un conjunto de bloques de datos más pequeños que pueden cargarse y procesarse de forma independiente. Un objeto blockedImage
admite imágenes grandes con uno o varios niveles de resolución.
