[OpenLayers-Users] RE OL 2.13 and WMS from qgis-mapserver

[Gaëtan Palka]

Thank you for your help. It is a problem of projection and of WMS:
- my shapefile for WMS are not visible at a scale greater than 1/500000
when the EPSG = 4326. Why ? I do not know because I have not this problem
on windows
- so I reproject my data in EPSG 900913, create my WMS and force the
default projection of the map in 900913 and all is OK.

I only have now to use Proj4js to be able to use EPSG:2154 (French offical
projection) directly without having to reproject each shapefile in 900913.

Thank you very much !
