Hi Bill,<br>
thank you very much: now I'm able to generate the map. I have use your
second option.<br>
<div id="result_box" dir="ltr">I have some doubts about resolution
parameter.<br>
If I do not specify this parameter, which resolutions will be chosen?<br>
If I want to specify resolutions, which criteria I must follow? I kwow
the original resolution of my base map (nearby 1 pixel = 80 meters), I
must choose multiples of the original resolution (160,320,640,...)? Do
I must specify the same resolutions in the openlayers file to obtain
that the final user will zoom only in cached images?<br>
<br>
Thank you very much again,<br>
<br>
Andrea<br>

<pre wrap="">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

<pre wrap="">Hi Bill,
thank you for your reply, but it does not solved my problem.
I have put my resolution and changed Layer.py, but I have always these
errors:

I'm becoming a little mad.
Thank you again,

Hi Andrea,
I had to put my own resolutions into my tilecache.cfg and not use the
defaults
my resolutions (for srs=EPSG:4326) is like this;
resolutions=1.40625,0.703125,0.3515625,0.17578125,0.087890625,0.0439453125,0.02197265625,

0.000002682209014892578125
and I had to tweak the tileCache code ("Layer.py") around line 137
from
if exact:
to
if not exact:
Hope that helps,

<pre wrap="">Dear all,
I'm testing TileCache and it's really a good tool. I'm very impressed.
I have made my first test with the original example file and now I want
to make some test with my map sources.
I'm not able to use as source a wms server of mine. TileCache does not
create the image tiles in the cache directory, and I have an empty map
in my openlayer interface.
This wms server works properly as you can see using this url:
<a class="moz-txt-link-freetext" href="http://esempi.mapserver.it/cgi-bin/mapserv.exe?map=/Siti/mapserver/esempi/map109/config/progetto_109_wms.map&layers=gra_isud&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image/png&SRS=EPSG:32633&BBOX=201153,3929400,849098,4626420&WIDTH=256&HEIGHT=256">http://esempi.mapserver.it/cgi-bin/mapserv.exe?map=/Siti/mapserver/esempi/map109/config/progetto_109_wms.map&layers=gra_isud&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image/png&SRS=EPSG:32633&BBOX=201153,3929400,849098,4626420&WIDTH=256&HEIGHT=256</a>
I have inserted these lines in tilecache.cfg:
[acido]
type=WMSLayer

extension=png
layers=gra_isud
bbox=201153, 3929400, 849098, 4626420
srs=EPSG:32633
I have these lines in apache error log:

What's wrong in my settings?
