pdfmap directly deals with the canvas object, so maybe this is not
what you want. Anyway, maybe you could convert the informations about
your points to pdfmap's input format, and see what happens. My guess is
that pdfmap can do what you want, but it depends on if you want to do
more complex things or not.
