Hi Andrea, Ian,
Thank you for the quick answers.
Good to know, I'll set that in my sld 🙂.
And yes Ian, my output format supports transparency, as I'm using it already in
other slds without any problem! But a good point I should have checked first.
Thank you both again 🙂
All the best,
Greg for BruGIS

Objet : Re: [Geoserver-users] sld fill-opacity on mark in graphic graphic
stroke stroke not working?
Hi Grégoire,
I can confirm it's the case... the situation is confusing, because for a
Graphic object one can set an opacity at the Graphic level,
which does work:
<sld:Graphic>
<sld:Mark>
<sld:WellKnownName>circle</sld:WellKnownName>
<sld:Fill>
<sld:CssParameter name="fill">#ff0000</sld:CssParameter>
<sld:CssParameter
name="fill-opacity">0.5</sld:CssParameter>
</sld:Fill>
</sld:Mark>
<sld:Size>12</sld:Size>
<sld:Opacity>0.5</sld:Opacity>
</sld:Graphic>
[image.png]
I guess that for the fill and stroke within the mark, one could multiply the
internal opacity by the graphic's own opacity?
But right now it's not done, and the graphic opacity is overriding whatever you
set for fill and stroke.
Regards,
Andrea Aime

Hi,
I have a rather simple sld symbology that intends to represent lines by

here is my sld:

I'm under Geoserver 2.24.2, and everything works except the fill-opacity. Is
there a known bug there, or do I do something wrong? I did try to put a
stroke-opacity just after the stroke-dasharray CssParameter, but it's not
working either...
Thank you already for your ideas/help,
Greg for BruGIS
