[mapserver-users] Color the world, but not my country

[Jeff McKenna]

Hi Wim,

I face this issue quite often, and I often use the IMAGECOLOR parameter 
setting in the mapfile for this.  It's a nice trick to show blue water, 
for example, all around your features.  Here is an example:

   MAP
     IMAGECOLOR 0 0 255
     ...
     LAYER
       ...
     END #layer
   END #mapfile
