[Tilecache] Symbol image transparency problem

[Jez Walters]

Jeff,

Thanks for the advice, but how exactly do I do as you suggest?  Do I need to set the "extension" parameter, and if so what value should I use - the online documentation<http://tilecache.org/docs/README.html> doesn't indicate how to use this parameter.  I tried adding "extension=png", but that didn't change anything.

Warm regards,

Jez

Hi Jez,

if you want transparency using tilecache, be sure to set png and not jpeg in the tilecache config.

Perhaps this might help

Hello TileCachers,

I'm not sure if I posted this question correctly last time, so I'm trying again! ;-)

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

I don't have that much experience of TileCache, so any help/explanation would be most appreciated!

Jez
