[Qgis-user] qgis python script, add raster to bottom of map

[Johannes Kröger (WhereGroup)]

Hi Tim,

there are multiple options:

You can consult the QGIS PyQGIS cookbook for an example: 
https://docs.qgis.org/3.16/en/docs/pyqgis_developer_cookbook/loadlayer.html#qgsproject-instance

Or when you google for "pyqgis add layer" plus "order", "bottom" or 
"specific index", those terms should get you going with various examples 
at gis.stackexchange.com. Those are for a number of different use cases 
so best look around yourself what best suits you.

Cheers, Hannes
