[Therion] How to properly scale xvi for using as a background image for drawing

[Marco Menchise]

Yes, I'm using Topodroid.

Topodroid sketches are exported using a scale factor of 39.37, so to create
a proper .xvi I had to use the following thconfig (let's say survey,th
contains centerline data and splays):


------------------------
source survey.th
layout topodroidlayout
scale 1 39.37
endlayout
export map -proj plan -layout topodroidlayout -output background.xvi
------------------------


After that I'm able to use the generated .xvi as the backround for the
Topodroid sketches in xtherion.

Thanks to Marco Corvi for the explanation.
