Method of sorting two-dimensional graphic images for converting into raster lines

A method for sorting two-dimensional graphics data into raster lines is described. The method decomposes the graphic images into vector line and arc segments with their associated two-dimensional coordinates. A vector or sub-shape list is then established containing the coordinates of all the vector lines and arcs. Sorting is then performed on the vector data by organizing each vector based upon its X- or Y- coordinate information. Pixels that make up each sub-shape are then computed. This computation is performed for each sub-shape in the order given by the sorted, sub-shape list. The resultant pixel list is ordered according to the X- or Y- dimensional sort previously performed. Pixels generated in a partially pre-sorted arrangement are arranged in a pixel array. The stored pixel array is then used to form raster lines.
