[mapserver-users] Inverted polygon shapeburst effect

[Kalbermatten Michaël]

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
