Hi Guys,
I'm pretty new in GIS Area and already have a question.
I'm currently testing the v2.0.2 of GeoServer and tried parameter substitution.
I succeed to use it according to the documentation on some part like
CssParameter in Font and Fill section, Radius in Halo section, but I failed
using it in VendorOption section. I wanted to dynamically set the spaceAround
parameter. Here follows significative parts of my SLD.
[...]
<TextSymbolizer>
[...]
<Font>
<CssParameter name="font-family">
<ogc:Function name="env">
<ogc:Literal>TownNameFont1</ogc:Literal>
<ogc:Literal>Arial</ogc:Literal>
</ogc:Function>
</CssParameter>
<CssParameter name="font-size">
<ogc:Function name="env">
<ogc:Literal>TownNameSize1</ogc:Literal>
<ogc:Literal>12</ogc:Literal>
</ogc:Function>
</CssParameter>
<CssParameter name="font-style">normal</CssParameter>
<CssParameter name="font-weight">normal</CssParameter>
</Font>
[...]
<Halo>
<Radius>
<ogc:Literal>
<ogc:Function name="env">
<ogc:Literal>TownNameHaloSize1</ogc:Literal>
<ogc:Literal>2</ogc:Literal>
</ogc:Function>
</ogc:Literal>
</Radius>
<Fill>
<CssParameter name="fill">
<ogc:Function name="env">
<ogc:Literal>TownNameHaloFill1</ogc:Literal>
<ogc:Literal>#FFFFFF</ogc:Literal>
</ogc:Function>
</CssParameter>
</Fill>
</Halo>
<Fill>
<CssParameter name="fill">
<ogc:Function name="env">
<ogc:Literal>TownNameFill1</ogc:Literal>
<ogc:Literal>#000000</ogc:Literal>
</ogc:Function>
</CssParameter>
</Fill>
<Priority>
<ogc:PropertyName>pop</ogc:PropertyName>
</Priority>
<VendorOption name="conflictResolution">true</VendorOption>
<VendorOption name="spaceAround">
<ogc:Function name="env">
<ogc:Literal>TownNameSpaceAround1</ogc:Literal>
<ogc:Literal>12</ogc:Literal>
</ogc:Function>
</VendorOption>
</TextSymbolizer>
[...]
Is this functionality unavailable on VendorOption or am I doing something wrong
?
Thanks in advance.
Cheers,
