[Geoserver-users] White lines between image pyramids in layer group

Hi list,

I’ve a number of abutting but non-overlapping image pyramids that I’ve joined together in a layer group. However, there appear white lines between the image pyramids when viewing the layer group using WMS.

I don’t think there is a data problem, since the white lines do not appear a) when I open the individual files in QGIS, and b) when I create a single image pyramid using the underlying files.

Any tips?

Cheers,

Tim
