ABSTRACT:
Methods, systems, and articles of manufacture consistent with the present invention improve drawing operations for drawing an object that has object information onto a background image, which has background image information, already displayed on a display device. A sub-region of the object including at least one pixel intersected by a boundary of the object is determined, where the sub-region corresponds to a portion of the background image information. It is determined whether the portion of the background image information corresponding to the sub-region is stored locally with respect to a program or remotely with respect to the program. When it is determined that the portion of the background image information is stored locally, the portion of the background image information is retrieved locally to facilitate generating a redrawn sub-region of the object.
