"see through" so if you have an ECW that covers the City, mapserver
will fill the rest of the image with a color (typically white).
Transparency comes into play, because if you serve the image as a PNG or GIF
then the "white" becomes "see through" (aka
"transparent").<br>

This isn't a limitation of Mapserver or GeoMOOSE, it's a limitation of the JPEG

<br>
If it's raster it's a little harder to deal with because it's probably being
served as a JPEG and JPEG's don't support transparency.<br>
<br>
If it's a GIF then it's pretty easy to just set the image as transparent, so if
there isn't any data it shouldn't show up.<o:p></o:p></span></p>
