<p>I see: at first glance, I misunderstood your suggestion, so I
didn't get it correctly.</p>
<p>Indeed it works.</p>
<p>Is there actually any difference at all, with regards to my aim
(i.e., just draw a line through two points which extends beyond
the two points), between scale and stretch?</p>
<p>Because even if both this workarounds work, the solution proposed
by Otfried looks more appropriate for the theory.</p>
<p>Thanks</p>

<p class="">Sorry but this workaround doesn't help in my

<div>If you use « scale » it preserves the orientation of the
segment.</div>
<div>It does exactly what you want.</div>

<div>(Use « scale » not « stretch » , stretch is an affine
transformation, scale is an homothety, scale is obtained by
using stretch mode + shift)</div>
