20090317011DEVICE AND METHOD FOR SIMPLIFYING VECTOR GRAPHICS - Today's computer programs that convert raster images into vector-based images do not optimize/compress the vector representation of the vector-based images. Instead, they simply keep all of the complex edges for the vector objects within the vector-based images. The present invention described herein functions to create a compressed vector-based image by simplifying the shapes of common complex edges which are shared by adjacent vector objects. The compression (lossless compression) of the vector objects is done without affecting the perceived quality of the vector-based image.12-24-2009
