Hi Vincent,

Now is a good time to update your LMTX installation, since the current version
(October 10th) works well in many regards (esp. footnotes).
I didn’t check yet some areas that are known to be problematic, like columns,
but my projects with hundreds of footnotes (including side floats in footnotes
implementations i guess).
Hm, you implemented these boxes only in 2015, there was not much change in that
regard since then.
Way earlier but it wasn't enabled ... (I'm not going to check ancient

then didn’t check enough if it does what it should.)
I long ago lost track of what all that means ... decades of pdf ...
different viewers, different interpretations ... validators complaining
about things missing ... i guess that bit (like annotations) will always
be in flux (also because specs
more?).
I gave up on that subject and still fix the boxes with Acrobat Pro whenever I
need them to be correct. But that’s no solution.
(And it’s probably also my fault, since I was one of those who wanted this
implemented and then didn’t check enough if it does what it should.)

How is this different from reading files from a zip file?
no duplicates, so in my use case .8 G instead of 1.8 G, with selective
compression (no need to zip jpg or png), probably also bit more memory
friendly and faster but i didn't check that (it's
#x27;img')", so I guess this got renamed or moved?

Since I don’t know what the function is supposed to return, I thought I’ll
check:
local image = figures.getinfo(imgname,1)
print("TEST", image, #image)
for k, v in ipairs(image) do
