If you're talking about starting from a JPEG and turning it into a scalable image, then yes, you're looking for miracles. It's kind of like starting with a hamburger and trying to turn it into a steak. Getting placement correct, however, should be possible, but it's more of a TeX question, and you might want to ask the TeX experts. Most of the conversion programs on the page you referenced are in the FreeBSD ports tree, so you shouldn't have trouble using them if you want.
