<DIV><FONT size=2 face=Arial>I had similar transparency problem before and
solved it with the correct OUTPUTFORMAT setting of the Mapserver map
file. YOu did not show your OUTPUTFORMAT setting in your map file but I
assume that the IMAGEMODE is RGB. RGB mode does not support transparency
(check Mapserver documentation <A
href="http://mapserver.org/mapfile/outputformat.html">http://mapserver.org/mapfile/outputformat.html</A>)
. Yes, it is strange for even with that setting, transparency works in
OpenLayers. Anyway, make the following changes and add the following
OUTPUTFORMAT setting bellow in your map file and see if it
works:</FONT></DIV>

for the advice, but how exactly do I do as you suggest? Do I need to set

<P class=MsoNormal>I'm displaying UK Ordnance Survey MasterMap vector maps
using OpenLayers, TileCache and MapServer. The maps display perfectly when I
use just MapServer ( <A
href="http://osgeo-org.1803224.n2.nabble.com/file/n5389483/MapServer.jpg"
target=_top>MapServer.jpg</A> ), as well as when I also use OpenLayers.
However, when I add TileCache to the mix, the various symbol images are no
longer transparent ( <A
href="http://osgeo-org.1803224.n2.nabble.com/file/n5389483/TileCache.jpg"
target=_top>TileCache.jpg</A> ).<SPAN

style="FONT-FAMILY: 'Calibri','sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt"><o:p> </o:p></SPAN></P>
<P class=MsoNormal>I don't have that much experience of TileCache, so any
help/explanation would be most appreciated!<SPAN
