Bug report #8359
Remove warning about WMS

When printing a layout that contains a WMS, we get a warning about max size.
I think this is useless now, as the print driver automatically tiles up the WMS request, and can be confusing and misleading for users.
Better remove the warning.

The warning is
Some WMS servers (e.g. UMN mapserver) have a limit for the WIDTH and HEIGHT parameter. Printing layers from such servers may exceed this limit. If this is the case, the WMS layer will not be printed
and imho it's more misleading than helpful because the reason why WMS do not print in my experience is if the output resolution is set to something bigger than 75 dpi. (Tested with http://data.wien.gv.at/daten/wms?service=WMS&request=GetCapabilities&version=1.1.1)

What do you suggest for making the message more understandable for QGIS users? For me as a Mapserver user it does make sense and the current message probably tells what really happens: with screen size of, let's say, 800 x 600 pixels the raised output resolution leads to bigger WIDTH & HEIGHT (1600 x 1200 or so) in the GetMaps and MapServer will not send a map.

Hi Anita, this is not what I see, I can print layouts with WMS layers at above 75dpi. The limit should be set at server level, not a qgis issue.
Anyway regarding the original description: I does not seems to me that the print composer automatically tiles WMS layers. It does if of course it was choose to do it when the layer was added in the project using the WMS client and the option "tile size".

Unclear to me whether this has been solved.
I don't think the wms layers are automatically tiled. They are if in the client the user choose to add it with a tiling strategy. So the warning still makes sense and this ticket should be closed.
