How to include Goole Map in PDF cfdocument

We have a Google premier license and use it to create maps displaying markers defined by database lat/long values.  I want to include one of the JS API generated maps inside a PDF we create using cfsavecontent and cfdocument.  However, the map canvas is always blank when viewed inside the resulting PDF. Is there any reliable way to do the cfdocument step *after* the map has loaded on the user's screen or save the map canvas to our server as an image so we can include it in the cfdocument?

Many thanks for any assistance provided.
