I gave a talk on this at svg open 2004 last week.

The simplest way to do it, which produces the largest file size, is to
take each pixel and generate a rectangle of size 1x1 and give it the
correct colour. All you need to do this is a bitmap processing library.

Alternatively, you can use autotraced (but this is an external tool).

Finally, you can contact me off line and we can discuss how Vectoreal can
do this for you by implementing some of the image-processing. We have the
tools and the algorithms to do the image processing and could build you an
application to do this.
