A graphical object rendering system for the rendering of images from edge based object descriptions, into pixel based data, is disclosed. The system includes a buffer that comprises an array of storage structures to hold pixel level data, with each pixel level data structure further comprising a series of setable level indicators. A separate storage arrangement is provided for storing an edged based object description of the desired image, each edge of each object having a level value corresponding to the level of the object. An edge insertion means is connected to the buffer and the storage arrangement, to alter the setable level indicators at locations corresponding to any intersection of the edges with the pixels. A highest object determinator is configured to determine the object with the highest currently active level, the highest object determinator being connected to the buffer and, for each corresponding pixel level data structure of the array of pixel level data structures, it determines the object with the highest currently active level. <IMAGE>
