Abstract:
A computer-readable medium having computer-executable instructions for performing steps including:(a) detecting first indicia indicative of a first race condition threshold being met for a band from a page of image data; (b) responsive to the first indicia, pre-rasterizing the band to form a pre-rasterized band; (c) responsive to the pre-rasterizing, detecting second indicia indicative of the pre-rasterizing not being required to enable normal completion of image processing for the band; and, (d) responsive to the second indicia, comparing an estimated memory consumption of an estimated compressed form of the pre-rasterized band with a memory consumption of a display list associated with the pre-rasterized band, and keeping one of the pre-rasterized band and the display list, whichever consumes less memory, and freeing the other.
