Description

In qgis-server (I tested with last dev), when using a categorized renderer and GetLegendGraphics, the returned image doesn't show the LayerName as title of the layer in the legend. Like in this sample:

Or this other for single-symbol rendering:

AFAICT it would be better to use the the metadata title (when filled) in the legend. In fact the layername is often a non-understandable code while the metadata title is a human understandable value.

I asked on ML, whether this is a regression and was asked to opened a ticket.

Thx.

is this a regression compared to previous qgis server releases? cheers!

I try to test is directly.

But is not so easy.
I dont know how to maintain two completelly distinct versions of qgis-server on the same machine.

So the only solution is remove the dev and compile the 2.4
This require some time to do.
I hope to do this early.

Hi,
I confirm is a regression.
I tested it on qgis 2.4 e correctly appear the ttles.
I attach two images to show the results from the same getlegendgraphics .

I add also the two images for the same requests on the same datasets and same project qgis using a qgis 26 server.

The second image show clearly that in the title of layer , qgis 2.6 server , is using the layer_name :

"elementi_franosi_single_renderer"
instead of the title ad available from Metatada->Title ("Title of layer")

Same proble when using the Categorize rendering.

I dont test for rule-rendering but I guess more probably the problem is also in it.
