Conversion of the display list to an intermediate format representation is estimated to succeed within available memory. The method proceeds to rasterizing the display list, i.e. to convert the display list to the intermediate format representation. If a memory allocation request fails during conversion of the display list to the intermediate format representation (630), the display list is split (625), in z-order, into at least two sub-display lists to reduce a number of objects on a scanline to be processed at a time. An intermediate format representation is generated (680) for each of the sub-display lists to render the graphical representation. By splitting the display list, in z-order, the method facilitates completion of the rasterization of the graphical representation within the available memory. 13753095_1
