then the image around it shows. However, the quality of the image is poor
so I cannot use it. So I am back to using ECW. Thanks
again.</FONT></SPAN></DIV>

<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: arial,helvetica,sans-serif">
<DIV>Images being served as a JPEG are not "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><BR>This isn't a limitation of Mapserver or GeoMOOSE, it's
a limitation of the JPEG format.<BR></DIV>

<DIV><SPAN class=623035719-07112008><FONT face=Arial color=#0000ff size=2>The
image is an ECW but JPG acts the same way. My question is why does
transparency come into play when I do not want to see under the image, I want
to see beyond the extent of the image. For example the image is 1 mile
by 1 mile and it still covers up the whole county. Is that because the
mapserver still thinks the image is county-wide?</FONT></SPAN></DIV>

<DIV style="FONT-SIZE: 10pt; FONT-FAMILY: arial,helvetica,sans-serif">
<DIV>What type of layer is it?<BR><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.<BR></DIV>

<DIV><SPAN class=113060417-07112008><FONT face=Arial size=2>Hope to have
better luck with this question.. Does anyone know how I can keep an
image that covers only a city from covering up another image below it that
covers the entire county? The extent doesn't seem to work for me in
the mapfile.</FONT></SPAN></DIV>
