@mhugent LAYERTITLE doesn't seem to work

[luca76]

@rldhont I'll see your problem next week. Meanwhile please explain it

Hi @luca76 here are exemples :

qgis_mapserv.fcgi?map=/path/to/lizmap/lizmap/install/qgis/montpellier.qgs&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetLegendGraphics&LAYERS=edition_line&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&TRANSPARENT=TRUE&WIDTH=150

qgis_mapserv.fcgi?map=/path/to/lizmap/lizmap/install/qgis/montpellier.qgs&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetLegendGraphics&LAYERS=edition_line&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&TRANSPARENT=TRUE&WIDTH=150&LAYERTITLE=FALSE

qgis_mapserv.fcgi?map=/path/to/lizmap/lizmap/install/qgis/montpellier.qgs&SERVICE=WMS&VERSION=1.3.0&REQUEST=GetLegendGraphics&LAYERS=edition_line&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&TRANSPARENT=TRUE&WIDTH=150&LAYERTITLE=TRUE

I have thought that if LAYERTITLE = FALSE, layers title have not be drawn.
@mhugent what do you think about this ?

[luca76]

@rldhont My fault. I've pushed a patch to QGIS, and inverted the value of LAYERTITLE.
Now I'll fix it. Thank you! :-)

[mhugent]

Is it ok in 47cf096 ?

[luca76]

see my comment: It should be on RULEITEM, too :-)
