[Tilecache] tilecache problem with a projection in meters

[olivier.terral]

Hi,

I test Tilecache but I've a problem.

Crschimdt said me maxResolution='auto' creates problem so I create my 
layers and map with maxResolution=47524   ( It's a world mercator 
projection in meters) and a maxExtent

but I've still another problem:

Here, definition of layer in tilecache.cfg:

[world]
type=WMSLayer
url=http://localhost/wms
extension=gif
srs=EPSG:54004                  
bbox=-19977777,-8938601,20037508,19813476
maxResolution=47524


Error in browser:

An error occurred: couldn't calculate tile index for layer world from ([-7811609.5890739998, 4724576.1282660002, 4354557.8218529997, 16890743.539191999])

    return self.getMap(param)
  File "C:\www\mdweb\1.5\tilecache-1.4\TileCache\Service.py", line 124, in getMap
    % (layer.name, bbox))


error in Apache:

for information wms works good, it's a mapserver wms and the layer is 
displayed correctly
 but with tilecache it bugs
