Many thanks for your reply, Hans.
Already wikified at

Many thanks again for your help,

Is there a way that I can get a number from context.figureheight, such
as I get it from tex.dimen.paperheight?
Sorry for insisting, I need it for a Lua script that in the relevant
line reads:
loader_times:write('.box placeholder width=' .. context.figurewidth
.. ' height=' .. context.figureheight)
I cannot concatenate string and function (and I need the number, not the
unit).
Is there no way of doing it?
i'm pretty sure this has been asked before
\ctxlua{local f = figures.getinfo("cow.pdf") print(f and f.used and
f.used.width)}
so .. time to wikify it

Re: [NTG-context] getting number from context.figurewidth
Hi, Pablo. I have no idea of what you need to do, but in grph-inc.lua you
find the following (line 709):
implement { name = "figurestatus", actions = { get, context }, arguments
= { "'status'", "string", "string" } }
So that \figureheight calls this function via \clf_figurestatus and, in
turn, it calls figures.get. If I'm right,
figures.get('status','height','0') -- or '"status"' ?
would have to return the value you're asking for (at the TeX end, "sp"
units are added). A MWE wouldn't hurt. I hope this helps or, at least, it
leads you through the right direction.
Cordially,
Jairo

Sorry for insisting, I need it for a Lua script that in the relevant
line reads:
loader_times:write('.box placeholder width=' .. context.figurewidth
.. ' height=' .. context.figureheight)
I cannot concatenate string and function (and I need the number, not the
unit).
Is there no way of doing it?
Many thanks for your help,
Pablo
