Hello, I found a solution to my problem, Dane advised me to use metatiles but this is not efficient.
A solution is add a gutter parameter in layer option. As my images have a size of 30pxl, the gutter should be at least 30pxl. This solution generates images larger but the tile is correct. http://openlayers.org/dev/examples/gutter.html Alex Dane Springmeyer a écrit : > Alex and I follow-up on this issue on IRC, but just for other's > benefit that may have run into this. > > Other than using metatiles like Jay recommended (which is great for > tilecache), in OpenLayers you can also use the singletile mode. > > It may not be ideal from a perfomance perspective but it is an easy > workaround: > > http://openlayers.org/dev/examples/notile.html > > Dane > > > On Nov 6, 2008, at 9:04 AM, Alexandre GARRAUD wrote: > >> Hello, >> >> I have a problem with ogcserver and openlayer.
