[QGIS-Developer] QGIS server question: opacities of selection colors in a layer

[Andreas Neumann]

Hi,

I am refering to the SELECTION parameter in QGIS server, as described in 
https://docs.qgis.org/2.18/en/docs/user_manual/working_with_ogc/server/services.html#getmap 
- see section on "SELECTION"

I am trying to achieve a transparent selection, so that layers beneath 
the selected layer can shine through. I thought that QGIS server would 
pick up the selection color and opacity of the project - but apparently 
this isn't the case. Is there a possibility to influence selection color 
and opacity in QGIS server?

My tests were with QGIS server 2.18. Not sure if things have improved in 
version 3 in this respect?

Thank you for your replies.

Andreas
