[Geomoose-users] Image display covers up layers beyond itsextent

[Nelson Soto]

Check your rendering output of your map files, particularly for the ECW
map file. Is this just in a particular browser or across all? You may
also be providing the extents of the whole county to your one image,
causing a stretch.

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?

	What type of layer is it?
	
	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.
	
	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.

	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.
