Initiall y, an image described by raster content having an original number of bits per pixel is provided. The image is divided into tiles such that each of the tiles represents a portion of the image. Then, for each of the tiles, a determination is made on how best to represen t the tile, as a collection of rectfills, imagemasks, raster data or a combination thereof.
