gdal_translate has lots of options for adding a georeference.
I don't know what would happen for a vector pdf, but if it is
a raster there should heno problem translation from a pdf to 
a pdf.

Note that you need the corners of the image file;
many maps have a border, so the corners of the map
may not be the same.
