Description

WMS Request doesn't work as expected with a different projection than EPSG:4326.

The parameters BBOX and WIDTH and HEIGHT doesn't match with the SRS parameter. It doesn't match either with the projection of the map.

Here is the url of the WMS : http://www.geosignal.org/cgi-bin/wmsmap?

The projection of the map is 27582 : NTF (Paris)/France II and all the layers included the WMS layer are in this projection.

Here is the error of QGIS :

Ne peut dessiner GéoSIGNAL parce que:
(code d'erreur inconnu d'un serveur de post-1.3 WMS) 
 Le fournisseur de WMS a également rapporté: 
msDrawMap(): Image handling error. Unable to initialize image.
msCalculateScale(): General error message. Invalid image extent, minx=2.407860, miny=46.227500, maxx=2.407860, maxy=46.227500.

  C'est probablement dû à un bogue dans le rapport du programme QGIS. Reportez cette erreur. 
 URL Éprouvé:http://www.geosignal.org/cgi-bin/wmsmap?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=-6.062580,41.163200,10.878300,51.291800&SRS=EPSG:27582&WIDTH=1&HEIGHT=1&LAYERS=RASTER4000k&STYLES=&FORMAT=image/png&TRANSPARENT=TRUE

Indeed, the url should be :
http://www.geosignal.org/cgi-bin/wmsmap?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=0,1600000,1250000,2600000&SRS=EPSG:27582&WIDTH=500&HEIGHT=400&LAYERS=RASTER4000k&STYLES=&FORMAT=image/png&TRANSPARENT=TRUE

Qgis set a good SRS (EPSG:2758) but the BBOX is false.

  • Resolution set to fixed
  • Status changed from Open to Closed

I tried to load the layer Raster4000k and it works as expected with the current development version (both with selecting wgs84 or epsg 27582), resulting in the following request.

http://www.geosignal.org/cgi-bin/wmsmap?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=203937.807137,1958513.266930,952342.514623,2648158.927134&SRS=EPSG:27582&WIDTH=969&HEIGHT=893&LAYERS=RASTER4000k&STYLES=&FORMAT=image/png&TRANSPARENT=TRUE

Please test and reopen the bug if it still occurs for you with the current devel version (or the rc version for 0.11.0 that should appear soon)

Regards,
Marco
