I am trying to publish maps from QGIS Map Composer.

I would like to automatically add the credits of the background layers displayed in the composition (like OSM, Bing, ...)

I am aware of such a feature in main QGIS window using
View -> Decorations -> Copyright label but

• this data is not shown in composer


• I am looking for an expression to adapt the text depending of the active layer

(Currently using either qgis 2.18 or 3.4)

One answer to your question can be a union of the great answers (in fact, your question is almost a duplicate) of this one: Automating citation of data source in QGIS print composer?

• Add a new text label to the layout.




• In the item properties of the label, main properties, click on Insert an Expression.




• In the expression builder, switch to the Function Editor tab, and paste this code:

# Be sure to import iface from qgis.utils



from qgis.core import *

from qgis.gui import *

from qgis.utils import iface



@qgsfunction(args='auto', group='Custom')

def get_layer_name(feature, parent):

    return qgis.utils.iface.activeLayer().name()  

Its define a new get_layer_name() function that returns the name of the active layer and can be found under the Custom group of the expressions list.

• Click on Save and Load Function.




• Switch to the Expression tab and write this expression:

layer_property( get_layer_name(), 'attribution')

It returns the Attribution metadata of the active layer.

Don't forget to refresh the layout view when the active layer has changed.
