Hello Pablo,
also Lua might be useful for you - some code like the one bellow, which
is based on an answer in this forum years ago:
----
assert(not figures.getinfo2)
figures.getinfo2 = function(name, page) -- [ [NTG-context] Pdf info with
Lua/Ctx API ]
if type(name) == "string" then
name = { name = name, page = page }
end
if name.name then
local data = figures.push(name)
local info = figures.identify()
if info.status.status ~= 0 then
figures.check() -- !Counts pages here!
end
figures.pop()
return --data
info
end
end
----
'info' might return not only width and height of the image, but also its
orientation/rotation.
And it would be up to you whether to swap width/height depending on
orientation.
Hope this helps.
Best regards,
Lukas

Iβm afraid this is the second time Iβm aware of the existence of
\ifdim
(the first time was when reading previous message from Taco π
).
Itβs a TeX primitive. From the TeXbook, chapter 20:
* \ifdim<dimen1><relation><dimen2> (compares two dimensions)
This is like \ifnum, but it compares two <dimen> values. For
example, to test whether the value of \hsize exceeds 100pt, you
can say β\ifdim\hsize>100ptβ.
The definition of \ifnum, right above it, states:
* \ifnum<number1><relation><number2> (compares two integers)
The <relation> must be either β<β or β=β or β>β. The two
integer numbers are compared to each other in the usual way, and
the result is true or false accordingly.
Many thanks for your reply, Arthur.
The explanation is extremely clear. I think I should try to read the
TeXbook (but I need time for this first).
Many thanks for your help,
Pablo
