[Tilecache] tilecache_seed between some bounds

[Adrian Popa]

Hello everyone,

I'm new to tilecache and I've managed to get it running, but now, to 
increase performance I would like to generate tiles between some zoom 
levels so loading will be faster.

I've read the documentation and I'm trying to generate the tiles with 
tilecache_seed.py. If I run it like this:

python tilecache_seed.py my_layer 1 6

... it starts crunching and generates loads of images. However, I've 
read it doesn't generate those images using the bbox parameter in 
tilecache.conf (so it's basically plotting the whole world). Now, I'm 
trying to cache layers 1 - 5 (as defined in my conf file) within my bbox 
- but the script finishes too quickly...

[root at terra tilecache]# python tilecache_seed.py my_layer 1 5 --bbox 
"20.26,43.16,29.70,48.46"
###### (64, 64, 1), (64, 64, 1)

Here is my layer configuration:
[my_layer]
type=WMS
debug=no
url=http://terra/fcgi-bin/mapserv?map=/var/www/html/map/my_base.map
layers=Judete,RuralSate,Rural,Urban,highway,sechighway,streets,buildings,GranitaJudete

spherical_mercator=true

extension=png
mime_type=image/png2

OpenLayers + WMS Layer pointing to tilecache.py works just fine, so I 
must be missing some parameters...

Thanks,
