[Therion] Georeferenced PNG export problem

Hi,

I want to export a map to georeferenced PGN. I am using the Xtherion 
"Help\Calibrate bitmap" function to register a PDF map to PGN, like 
explain in the next message.

https://www.mail-archive.com/therion@speleo.sk/msg02593.html

ThePNG is created appropriately, but I have problems with the ".MAP" 
file. When I execute the command, it creates a good PGN file, but 
creates an empty ".map" file. When a close Xtherion, the ".map" file is 
filled with the information. But that information is wrong, the 
coordinates are 0,0 (look attached file).

Wheres is my mistake?

An other question, can I convert the background to transparent directly 
from Therion. I want import the georeferenced PNG in Google Earth or 
GIS, and want only have the cave survey rendered and see the other 
layers around the cave.

Regards,

Evaristo.
