METHOD, APPARATUS AND SYSTEM FOR RENDERING A GRAPHICAL REPRESENTATION WITHIN LIMITED MEMORY

摘要

A method of controlling memory usage in a graphics rendering system. The method comprises converting a plurality of layers of graphical objects to an intermediate format representation, the layers being formed by grouping the graphical objects into a plurality of layers based on a first complexity threshold; and in response to detecting a memory shortage condition in execution of the graphics rendering system, determining a second complexity threshold based on the detected memory shortage condition, the second complexity threshold being lower than the first complexity threshold. The method also comprises identifying a layer of the plurality of layers based on the second complexity threshold, the identified layer being different to a layer which triggered the memory shortage condition, and converting the identified layer of graphical objects to the intermediate format representation to release memory occupied by graphical objects of the identified layer.
