does anyone know of formula's/methods of traceing images into vectors, basicaly what im looking to do is be able to feed php an image and have it find all the blackest lines and add instructions to draw it (that will later be read by a flash app), followed by the less dark lines, and the even lighter lines, and then find the solid colours (possibly a gradients if possible) and kind of scribble the darkness onto that area
i know this is a big ask, so any knowlage at all is apreciated, thanks! 😃
