    Abstract: Method and apparatus for management of image data using dynamic image pixel management for composite image display of image data so that "overlayed" and transparent images may be displayed, changed, and redisplayed in real time. On redisplay, the invention returns values of only those pixels, the values of which have changed, or any subset of all pixels. The invention is independent of the hardware used to display images and permits true color with transparency regardless of the number of display hardware bit planes available.
