You need to create a layout with a scale declaration in your thc file.

 

encoding  utf-8

source Litrikur.th

 

#export model -o litrikur.lox

 

#export model -fmt kml -o litrikur.kml

export map -projection plan -o litrikur.pdf

 

layout local

  scale 1 1500

  base-scale 1 1500 

endlayout

Subject: [Therion] locating where scrap outline intersects itself, and understanding the metapost log

 

[EXTERNAL EMAIL]

Hi!

 

I'm still having issues generating a pdf from my survey. Maybe it is because of the size of the scrap but I have not yet figured out how to work with multiple scraps so I hope I can make this work as a single scrap.

 

The metapost log tells me that the scrap outline intersects itself, but does not give any indication of where this happens. How can I find out what is amiss?

 

Right after the outline intersecting error I get the following:

 

! Value is too large (7219).

<for(picture)> q:=pathpart(EXPR0);tmp:=length.q;

                                                s:=decimal(roundone(xpart.po...

 

draw_downscrap->...te.s.to.clip_name;endfor;endfor

                                                  ;write"closepath fill"to.b...

l.14260 draw_downscrap

                      ;

 

I must confess I have no idea what this is trying to tell me. What value is too large? Why is the text formatted so strangely? Do the ellipses indicate where text has been clipped, and if so where can I find the full text?

 

I'm running Therion on Fedora 27 if that matters.

 

Here is the full text from the log:

The equation I just processed has given some variable a

value outside of the safetyp range. Continue and I'll try

to cope with that big value; but it might be dangerous.
