Hi Wolfgang,
thank you so much!
If we put the externalfigure setup in front, we can also calculate the spine width:
\getfiguredimensions[MAG]
\definemeasure [SpineWidth] [\dimexpr0.01mm * (\noffigurepages/2) + 0.5mm\relax]
Where 0.01mm is the paper thickness (100 g/m2) and 0.5mm is the folding addition – ask your printshop/bookbinder how much they need!
Greetlings, Hraban

Hi Tomáš,
I don’t know of anything existing. Find attached what I use for a magazine – I include title and back pages in the main PDF (to get a complete issue for corrections and online distribution) and use that as externalfigure, just creating the spine anew. Hi Henning,
below is a modified version of your example where I changed a few things.
1. I used the "measure" commands to set the spine values, the advantage of the \measure is that it falls back to 0pt when you try to use a undefined value.
2. I determined the last page of the megazine with the \getfiguredimensions command, afterwards you can use the \noffigurepages command to get the last page of the document.
3. I put the layer and frame settings for the \setlayerframed command in separate arguments.
4. I got rid of the backgrounds setup for the layer. A better solution here is to create a page without margins which can be done with the "page" layout where you flush the collected content of the layer with the \flushlayer command.
5. I set the texts for the isse number and title with the \setvariables command.
Wolfgang
