The thing is that I wonder to make it possible to calculate automatically the map rotation in map composer. I have many maps in one file with their own projection parameters, and I would like to define map rotation in map composer based on projection formula (or smth else?)
e.g. location one specific map in project:
The projection is
In map composer map boundary looks like
And with selected rotation angle for the map with their projection parameters:
Map rotation angle is different for every map depending on its location and projection parameters.
Is it possible to automate this process and calculate map rotation angle automatically, for do not find this value manually each time (I would like to create universal composer for all maps via atlas generation menu)?
