[MAPSERVER-USERS] transparency problem - unable to see raster undervector

[Fawcett, David]

Paul,

Try changing TRANSPARENCY ALPHA to TRANSPARENCY 30 (or OPACITY 30 if you
are using 5.0)

Either way, 30 refers to a 30% opacity value.

undervector



All,

I want to display a vector layer (roads) over a raster layer
(orthophoto). It seems that no matter what I try, the vector layer
remains opaque 
and I cannot see the raster image in the background.
I have tried the following (some were in desperation):
 - various incantations in the map file (see below)
 - change layer order in map file (although last in map file comes out
on
top)
 - tried calling out individual layers in URL
 - read lots of nabble entries

 
Here is my basic URL:
http://10.1.15.68/cgi-bin/mapserv.exe?
&map=/ms4w/maps/hybrid.test.map
&LAYERS=hybrid
&UNITS=dd
&PROJECTION=EPSG%3A4326
&SERVICE=WMS
&VERSION=1.1.1
&REQUEST=GetMap
&STYLES=
&EXCEPTIONS=application%2Fvnd.ogc.se_inimage
&FORMAT=image%2Fjpeg
&SRS=EPSG%3A4326
&BBOX=-122.48949990400003,37.752500096,-122.42699980800003,37.815000192
&WIDTH=256
&HEIGHT=256



Here is my map file:
MAP

	END

	END
	
END
