[mapserver-users] Rendering of adjacent dashed lines

[Ziegler Stefan]

Hi Thomas

Here are the screenshots from QGIS:

https://sogeo.services/tmp/dashed_line_01.png
https://sogeo.services/tmp/dashed_line_02.png

The first result I can get also with MapServer. The second one is the desired result which I'm not able to achieve with MapSever.

Regards
Stefan
