[OpenLayers-Users] tilecache config problem]

[bwoodall]

Hi Andrea,

Sorry for getting back so slowly, just deep in coding for a project.

Looking at you email, I believe the response is from TileCache not
finding the calculated resolution from the list of resolution(s) in
tilecache.cfg

The line in Layer.py ( around 125 ) is what causing this and you have a
couple of options ( maybe more )

1) find out why your bounding box that are being sent to TileCache are
not in line with the tilecache.cfg resolutions  (in Layer.py line 122 is
where the resolution is calculated)

2) change Layer.py around line 115 to
    def getCell (self, (minx, miny, maxx, maxy), exact = True):
        exact = False

Hope this helps

.......Bill,
