You could use KML export which can be loaded directly into google earth.

If you need to use bitmap output, PDF maps contain georeferencing
information (for nine points) as a comment. XTherion can use it to
produce PNG image + MAP Ozi explorer-like calibration file (Help ->
Calibrate bitmap). If your software doesn't load MAP files directly,
you would need to write some simple conversion script.
