Well...some of the graphics text books seem to think so. Also, I've written some back & forth convert functions between them (in the S language that is in our S-PLUS product, so not immediately useable for this task). If you can find an online version of something like the "Graphics Gems" books, there's probably something in there. If all else fails, I could translate what I've written into elisp, but I don't have a lot of time at the moment...
