If by messing it’s meant modifying their values, I agree that’s a bad idea 😊, the requirement is likely to read the value only (at least this is my usage of these in shipouts « after » callback). If these are not reliable, what’s the reliable way to get the page width and height ? Thanks Regards Joseph De : Hans Hagen

Helo, thanks both for proposals - I really need just to READ the values (and not to modify them). Best regards, Lukas On Thu, 08 Sep 2016 22:12:49 +0200, Hans Hagen wrote:

\ctxlua{context(number.topoints(tex.dimen.paperwidth))}

\ctxlua{context(number.topoints(tex.dimen.paperheight))}

Hello,

still a problem - consider the following code:

---- \ifx\startpapersize\undefined \unprotect \def\startpapersize{\page\pushmacro\page_paper_restore\setuppapersize} \protect \fi

\ifx\stoppapersize\undefined \unprotect \def\stoppapersize{\page\popmacro\page_paper_restore\setuppapersize} \protect \fi

%

\startluacode local tomm = function(v) return v * (210 / 39158276) end

pgsz = function() context("w=%.1f, h=%.1f", tomm(tex.dimen.paperwidth), tomm(tex.dimen.paperheight)) end \stopluacode

%

\starttext A \ctxlua{pgsz()}

\startpapersize[A3,landscape] B \ctxlua{pgsz()} \stoppapersize

\startTEXpage[width=200mm,height=100mm] C % 3rd page \ctxlua{pgsz()} \stopTEXpage

the papersize of a TEXpage is known when that page is flushed and when you ask for it the way you do now tex is still constructing the box it's all a matter of timing \starttext \appendtoks \ctxlua{ print( number.topoints(tex.dimen.paperwidth ), number.topoints(tex.dimen.paperheight) ) }% \to \everyshipout \setuppapersize[A4] test \startTEXpage test \stopTEXpage \setuppapersize[A3] test \stoptext

\stoptext ----

In the case of 3rd page (with text "C"), page size "w=210.0, h=297.0" is printed instead of "w=200.0, h=100.0".

So how to access values 200 and 100 mm for the page produced by \startTEXpage[width=...,height=...]?

Best regards,

Lukas
