It is determined whether any object of the one or more objects on the document page is a transparent object. If a transparent object is found, the document page is divided into a plurality of subregions. For each subregion, a set of one or more opaque object components is generated for any object having a location in the subregion. The document page is rendered, including separately rendering each of the plurality of subregions.
