[mapserver-users] Clip Raster with a Polygon

[Bob Basques]

I've done some interesting things by setting a background color, and
then removing features (NOT these) by coloring them WHITE, which is then
converted to transparent, which then works like a mask.

Hi, 

  

I have been thinking sometimes that there could be a huge polygon that
is always drawn on top of the raster layer.  'Area of interest' polygons
should be converted into holes in the mask polygon.  I have never tried
it in practice, though.

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 ?
