I have done this with static mask images. It wouldn't be hard to pass the ID of the feature that you want to be the 'hole' in the URL and then use that url variable in an expression for that layer/class .

'Area of interest' polygons should be converted into holes in the mask polygon. I have never tried it in practice, though. -Jukka Rahkonen- ________________________________ Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Gabe Codina Lähetetty: 18. helmikuuta 2011 7:05 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] Clip Raster with a Polygon Hi I would like to serve a raster layer that is spatially filtered - ie the raster should show through where it overlaps with 1 or more polygons. Is mapserver capable of doing this ? Gabe Codina
