[Geotools-gt2-users] Grouping Labels, Using Label Cache

[Ayyappa Das]

Hi,

My problem:- In the map generated using Tiger files, I have labels crowded together and I need a way to reduce the clutter.

I read some documentation saying that VendorOption maybe the way to achieve this.
I have tried the following in my SLD file:-
                    <VendorOption name="group">yes</VendorOption>
                    <VendorOption name="spaceAround">10</VendorOption>

With StyledMapPane, I found that this is not working and I guess this is not implmented in StyledMapRenderer.

I found that LiteRenderer uses this and does some sort of Label Caching using these options.

But using LiteRendererStyledMapPane or directly using LiteRenderer, I was not able to get it working.

I have already looked at http://docs.codehaus.org/display/GEOTOOLS/LiteRendering and http://docs.codehaus.org/display/GEOTOOLS/RendererLite. But somehow I am not able to get a Tiger file rendered with this.

a) Any other option for reducing label clutter?
b) Any other rederer implementation has this VendorOption implemented?
c) Any pointers in making LiteRenderer work with Tiger file?

Cheers,
Ayyappa
