With metaTile I can issue a pre-defined number of tiles that fit well. But this
is per-request (if I'm right). For instance, if I make two consecutive requests
of 4 tiles each from consecutive map zones, I get two sets of tiles that does
not fit with each other (the first 4 do not fit side by side with the second 4).
The problem with that approach is that tiles from the same request fit well,
but in order to construct a map like VE or Google Maps I need that tiles from
different requests to always fit well.
Please tell me If I am wrong.

Check the documentation on the "metaTile" it requires having PIL installed but
that is not really a big hassle.

Hi,
We are using Mapserver to produce tiles for a web application, using Tilecache
as the caching mechanism.
When we were building the system, we figured out that tiles requested does not
fit well side by side (the roads of one tile does not fit the prolongation of
the same road in the next tile). To eliminate this issue, we had to issue an
extra 10 pixels (around the whole tile) request to Mapserver and then cut them.
Then another problem arose: we could not make this with the labels because they
appeared cut in one tile and there was no prolongation of it on the next tile.
The solution was to divide it into different layers: one for the roads with the
10 pixels buffer and another for the labels without buffer. This has the impact
of duplicating the total number of images.
Anyone known an alternate solution for this problem?
Isn't Mapserver capable of serving images that fit well side by side?
Thanks in advance!
