1. A computer program product, tangibly embodied on a computer readable medium, for rendering an electronic document page, the computer program product comprising instructions operable to cause a programmable processor to: receive an electronic document page including one or more graphics objects, the graphics objects including at least one transparent graphics object; select a subregion of the document page where the transparent graphics object is located, the selected subregion having a complexity that does not satisfy a complexity condition; repeatedly divide the selected subregion into a plurality of smaller subregions, including computing a new complexity for each smaller subregion, until each smaller subregion has a complexity that satisfies the complexity condition; and process every smaller subregion to generate one or more opaque object components in the smaller subregion that represent an appearance of the smaller subregion.
