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.
Les programmes informatiques d'aujourd'hui, qui convertissent des images tramées en images vectorisées, n'optimisent/ne compriment pas la représentation vectorielle des images vectorisées. En lieu et place, ils se limitent à maintenir tous les contours complexes des objets vectorisés à l'intérieur des images vectorisées. La présente invention met en AEuvre des fonctions qui permettent de créer une image vectorisée comprimée par simplification des formes de contours complexes communs à des objets vectorisés adjacents. La compression (compression sans perte) des objets vectorisés s'effectue sans nuire à la perception de la qualité de l'image vectorisée.
