Dear list,
I have the following sample:
\starttext
\startluacode
document.sample = "xml-mkiv.pdf"
context.getfiguredimensions({ document.sample })
context(context.figureheight)
context.par()
context(tex.dimen.paperheight)
\stopluacode
\stoptext
Is there a way that I can get a number from context.figureheight, such
as I get it from tex.dimen.paperheight?
Many thanks for your help,
Pablo

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 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.
