[Therion] scrap-drawn maps to small by factor 2

[Christian Rößler (Roessler)]

Hallo everybody,

I noticed a strange problem drawing a quick survey of a little adit today. 
This being a little adit I immediately noticed that the scale bar is off 
by a factor 2, as 20 real meters (in the adit) gave 10 meters in the scale 
bar.

Then I fell back to Therion defaults (no values of mine, no input'ed 
metapost files etc.), but could not find anything unusual. I noticed then 
I had the same problem in the survey before, so I wonder. I forced the 
polygon draw printed besides the scraps-drawn map, then I saw the polygon 
draw is correct but the acrap-drawn outlines (via th2) are not. 

So I think I have done some mistake drawing the outlines (curve points 
followed by 'convert to curve'), but I cannot find anything regarding some 
scaling I have inadvertly done.

As I assume it has something to do with scraps, here the first scrap line 
from th2:
scrap scrap1 -scale [-128.0 -147.685 954.77 -147.685 0.0 0.0 
27.502357999999997 0.0 m]

Well, can anyone give me a hint? I will gladly give more information, if I 
just know which:).

By the way: I confess I have not read the attachment policy of the list. I 
risk a little attachment anyway; on may see the scaling mishap in the 
resulting pdf.

Best regards, Christian
