[Users] Tilecache + GeoExt Sublayers...

[Paul james]

I put all layers on tilecache.cfg :

[Layer1]
...
[Layer1Label]
...
[Layer2]
...

When I "Turn ON" two or more sublayer together I got that error:

An error occurred: Could not combine images: Is it possible that some layers
are not 8-bit transparent images?

(Error was: bad transparency mask) File
"C:\inetpub\wwwroot\Openlayer\TileCache\Service.py", line 323, in cgiHandler
format, image = service.dispatchRequest( params, path_info, req_method, host
) File "C:\inetpub\wwwroot\Openlayer\TileCache\Service.py", line 234, in
dispatchRequest raise Exception("Could not combine images: Is it possible
that some layers are not \n8-bit transparent images? \n(Error was: %s)" % E)


Cache miss: -180.0,-90.0,0.0,90.0, Tile: x: 0, y: 0, z: 0, time:
0.828000068665 Cache miss: -180.0,-90.0,0.0,90.0, Tile: x: 0, y: 0, z: 0,
time: 0.135999917984

Any idea?

Thanks
