Hello,

\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

Re: [NTG-context] Size of the last shipped page by Lua?
Helo,
thanks both for proposals - I really need just to READ the values (and not to
modify them).
Best regards,
Lukas

There are dimensions related to this :
local paper_width = tex.getdimen('paperwidth')
local paper_height = tex.getdimen('paperheight')
There is also :
tex.pageheight
tex.pagewidth
don't mess with these and don't rely on them
Not sure these are always same. Hope this helps,
Hans

Hi,
There are dimensions related to this :
local paper_width = tex.getdimen('paperwidth')
local paper_height = tex.getdimen('paperheight')
There is also :
tex.pageheight
tex.pagewidth
Not sure these are always same. Hope this helps,
Regards,
