I'm trying to create a universal template for different map sizes.
Typically, our maps have to fold up to A4 size, which means that the page size is a multiple of A4 in lots of different combinations. The template I want to create should automatically adjust the position and size of map elements (map frame, north arrow, scale bar, ...) in relation to the chosen page size.
Using the Expression string builder, is it possible to refer to the values of Width an Height in the Paper and quality tab?
I know that something similar can be be done using Atlas and the Expression string builder as shown in this example: Multiple format map series using QGIS 2.6 – Part 2
