Hi all,
I need to get ride of the red cross representing "no data" in the
"GetGraphicLegend" request.
[image: Inline images 1]
My idea is to create two different rules in the rastersymbolizer SLD style
descriptor.
The rule including the "no data" values with opacity = 0 will be used in
the "GetMap" request in order to get ride of the ugly background no data
values.
But I would like to use another rule (without the red cross;
"rule_no_redcross") which has not "no data values" on it to show the legend
of the raster without the redcross watermark in
the GetLegendGraphic request.
At the moment, specifying in the GetLegendGraphic request
"&rule=rule_no_redcross" I can make the red cross disappear from the
legend.
But the problem is I now get the background no data values on the raster
image in the GetMap request.
I think that in the GetMap request, GeoServer display all the rules for
that specific style.
So resuming, I want to create two rules;
- One rule to show the legend in the GetLegendGraphic request without the
red cross on it.
- Another rule to allow transparency to raster in the "GetMap" request.
My question:
Is it possible to add a parameter in the GetMap request to say:
hey GeoServer! I just want you to apply this style rule to this nice
layer. Please, proceed.
Thanks a lot!
Alberto
