RE: [GRASS-user] v.segment - how to use orthogonal offset?

Thanks, Markus, I'll check into it in more detail when I get back from the
field.

Here's a text file I prepared for use as stdin for v.segment:

P 1 2 100 100
P 2 2 200 100
P 3 2 300 100
P 4 2 400 100

The fourth column, according to the v.segment html page, is the

orthogonal

offset from the input vector. But no matter what I make this value,

the

output vector is never offset, it's always in the middle of the width

of the

line. What am I doing wrong here?

Maybe nothing (not sure):

It still doesn't work ...

I don't see any answer from Radim.

with
g.gisenv set="DEBUG=2"
you should see some related output how the file is parsed.

In the code I don't see that side_offset modifies offset1 or
offset2 (which it probably should).
