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.
