[Qgis-user] WMS Provider and the DPI parameter

[Andrea Peri]

Hi,
starting from ticket #6430 (http://hub.qgis.org/issues/6430)
I discovered that qgis wms provider when send a request to a WMS add a
parameter "DPI".

It is a not standard parameter, but main question I have is understand why
there is the need to use a "DPI" parameter.

Infact the standard wms request contain
a bbox and a map pixel dimension.
Perhaps I miss something, but AFAIK knowing the BBOX and the Pixel Size Map
I guess is possible to calculate the DPI value.

So put on a request BBOX, Pixel-SizeMap and DPI seem redundant to me.

Is right this ?

thx,
