i am not a programmer at all, so also script is out of my
knowledge. But to make what i am talking about you will need
2 parameters. First is scale ex 10px=30m, and then how many pixels
from point A to B.
Now i am doing it with calc. I am counting pixels at scale
and then if i know how many px is for 200m then i can count how
many meters i for 743px.
If someone will have solution i am interested in!
