Hi Alberto,
Yep, a <div> with a GetLegendGraphic (or even just a static <img>
if the legend is never going to change) would probably be ideal in this sort of
scenario.
Cheers,
Jonathan

Hi Jonathan,
Thank you for your ideas, the client is using OpenLayers 3 so I am considering
to use the second options. As you said, the layer can end up anywhere on the
screen but maybe if they create a div container with the GetLegendGraphic URL
the legend should looks ok?
Thank you,
Alberto

Hi Alberto,
I'm not sure this is possible with decorations. But two (non-ideal)
alternative ways to try and get the same outcome:
1) A second layer that you overlay client-side - the second layer would be
requested as a non-tiled image.
2) Creating a layer-group with a second layer which only contains your image as
a repeating watermark. The downside is that from the users perspective the
legend could end up anywhere on the screen
.
Cheers,
Jonathan

Hi all,
I am using "image" WMS decoration type to show the legend of NDVI rasters.
It works fine but as the client is required to use "tiled" services the legend
is shown as many times as tiles are for that image, which is not what we want.
I tried with "legend" WMS decoration type too, but still does not work.
This is the layout I put in layouts folder in GeoServer data dir:
<layout>
<decoration type="image" affinity="top,right" offset="15" size="auto" >
<option name="url"
value="file:///var/lib/tomcat7/webapps/geoserver/data/layouts/traditional_ndvi_scale.png"
/>
</decoration>
</layout>
Thank you very much for your help,
Kind regards,
Alberto
