Re: [Geoserver-users] Polygons with outlines using gradients

[Gabriel V. <gab...@mi...>]

Hy Chris,

If you can understand french, I found a tutorial on a blog about this 
question, some weeks ago. As Edward wrote it, you cna do it with 
buffers, and then display it wih different opacities.
Here is the article : http://simonmercier.net/blog/?p=1214

He creates buffers that do not overlap ("ring" buffers) on the server 
side, and then applie transparency and color with MapServer.
