One problem left with dimensions that I can’t reproduce in a minimal
example:
I want to calculate the spine width of the cover from the number of
content pages:
\useexternalfigure[CONTENT][book.pdf]
\getfiguredimensions[CONTENT]
\definemeasure[SpineWidth][2mm + (0.135mm * \noffigurepages/2)]
That works so far, if I output \measure{SpineWidth} it shows the right
size (~42pt).
But if I use this measure in
\setlayer[width=\measure{SpineWidth}]{...}
it’s very small.
I guess \noffigurepages is 1 at that point (from another image) and I’d
need to expand it first.
Am I right that the expansion happens only at the “execution” of
\measure? How would I do that? \expanded\noffigurepages doesn’t work.
Another issue:
0.135mm is the paper thickness of 90 g/m² (= 0.09mm per sheet) with 1.5
bulk. But
\definemeasure[SpineWidth][2mm + (0.09mm * 1.5 * 90)]
doesn’t work:
"""
Missing ) inserted for expression

.
<macro> \commalistcommand
2mm + (0.09mm * 1.
5 * \noffigurepages /2)
<macro> \measured
#1->\dimexpr \ifcsname \??measure #1\endcsname \lastnamedcs
\else \zeropoint \fi \relax
...
"""
I also tried 1.5sp since sp should be 1, but it didn’t help.
