Just an update... I found some kind of solution...
My polygon layer is a postgis layer, thus I just duplicated it in the mapfile,
and added a st_translate on the geometry using an attribute of the table.
In this new layer, I defined a class having multiple geotransform style tags.
Something like the code hereunder.
There is still some tuning to do and I don't know if that the best way to do
it... but it might help other people

Objet : [mapserver-users] Inverted polygon shapeburst effect
Hi,
I am looking for a way to create a shapeburst effect (or outer glow) on the
outer side of a polygon. This is something which has been added to QGIS (using
the inverted polygon option, see http://planet.qgis.org/planet/tag/shapeburst/)
I was wondering if something like that was possible in MapServer ?
I took a look at the doc but could not find anything relevant (maybe using
geotransform, but then, how do I create the glow...).
Does anyone have an advice ?
Thanks !
Michael
