Thanks Alex,

The "gutter" solution gives something better and the "singleTile" solve the 
problem.

Unfortunately I can't use them, because we are pre-generating tiles in order to 
have good performances, which means that I need a solution at the level 
MapServer (Mapfile and / or symbol file).

I've found that in The MapServer RFC Documentation 
http://mapserver.org/development/rfc/ms-rfc-45.html:

-----------------------------------------------------
Polygon fill symbols

Give hatches and vector fills a stable geographical coordinate origin (0,0) to 
better support tiling and continuous rendering of neighboring polygons
-----------------------------------------------------

Does it mean that the problem is known and  have been fixed?

 Best regards!

Larissa

Hello

you can use the parameter "gutter". Here an example
http://trac.osgeo.org/openlayers/browser/trunk/openlayers/examples/gutter.html

Or you can use the parameter onetile. Here another example

Betreff: [mapserver-users] Polygon hatch mismatch at tile borders.

Hi,

I'm using MapServer 5.4.2 and when I'm working with tiles the hatches of hatch 
filled polygons are not matching at tile borders. See example 
hatch_mismatch.jpg [cid:005501312@28102010-2087]

How can I solve that?

Thanks

Larissa
