Here's how easy it is to make a DocRaptor PDF with a Google Map Static image. After getting a Google Map's API key, just get the static map image URL and put it in your document:
<!DOCTYPE html>
<html>
<body>
<img src="https://maps.googleapis.com/maps/api/staticmap?center=40.714728,-73.998672&zoom=12&size=400x400&maptype=roadmap&key">
</body>
</html>
Note: This example image may not appear as after the example was created, Google removed support for free, keyless Google Map images.
