[Qgis-user] Symbol lines every km, moving when changing scale or moving map

[Prud'homme Jérémie]

Tested too fast :(

Behavior is ok when zooming in, but still problems when zooming out
(whereas the entire feature is visible !).
See here : https://www.zupimages.net/viewer.php?id=21/07/ehlo.gif

Circles should follow the strokes generated with the tool "Points along
geometry".
