Can anyone say if GeoServer honours the Opacity setting for an
externalgraphic composed of a png image (with transparent background)? I'm
sure I've done this in the past but I can't find the SLD file anywhere.
Currently I have:
<PolygonSymbolizer>
<Fill>
<GraphicFill>
<Graphic>
<ExternalGraphic>
<OnlineResource
xlink:type="simple"
xlink:href="../watermark_default.png" />
<Format>image/png</Format>
</ExternalGraphic>
<Opacity>0.5</Opacity>
</Graphic>
</GraphicFill>
</Fill>
</PolygonSymbolizer>
Which is (apparently) valid according to the SLD editor (and my reading of
the spec) but definitely doesn't make a transparent fill.
Cheers
Ian
