[NTG-context] Wrong page numbers in frontmatter
Hi, I'm not sure why the following MWE produces a document where page 2 has the page number i instead of ii. It seems to have something to do with the use of makeup. I was using it to create a vertically centered title page. Is there a better way of doing this which will give the correct page numbers?

Re: [NTG-context] Trouble setting PDF boxes
Hi Hans, using that produces a pdf which fails compliance with PDF/X-1a as the BleedBox is not set. But notice that if it did work, the sizes of TrimBox and BleedBox would be based off printpaperwidth and printpaperheight. I need them to be based off paperwidth and paperheight (for my documents all have printpaperwidth – paperwidth ≠ printpaperheight – paperheight). (Apologies, I initially replied to just you and not the list as well.)

Re: [NTG-context] Trouble setting PDF boxes
Hello, I'm happy to report that I got this working after much trawling
through the source and documentation. The code below produces a pdf with
the MediaBox, CropBox, BleedBox and TrimBox all in the places I specified
in my original message. I hope it helps illustrate how to set these PDF
boxes using Lua. I would much appreciate any feedback on how the Lua code
can be cleaned up or made more flexible (the bleed is hard-coded in because
I didn't know how to obtain the user-specified bleedoffset, for example),
or made better in any other way.

[NTG-context] Getting page width and height in Lua
If I want to get the paper width and height to use in some Lua code, I can use: local paperwidth, paperheight = backends.pdf.codeinjections.getpagedimensions() But what if I want to get the page width and height? That is, the width and height of the first argument in the two-argument version of \setuppapersize. Does anyone know how I can obtain these using Lua?

Re: [NTG-context] bug in PDF boxes? (was: Re: Trouble setting PDF boxes))
I would like to add though that even if the code you posted did work properly, Pablo, it wouldn't solve my original problem. It would be good if cropoffset, trimoffset etc. took two dimensions, one for the x direction and one for the y direction, instead of one for both. But I appreciate you changing the subject to increase visibility.

Re: [NTG-context] Trouble setting PDF boxes
After much searching, my probably laughable attempt consists of combining
the answer to the question at
https://tex.stackexchange.com/questions/433110/setting-page-attributes-of-every-page-in-a-generated-context-file
with
what I can see in the source at
https://source.contextgarden.net/tex/context/base/mkiv/lpdf-mis.lua:
\appendtoks
\startluacode
local formatters = string.formatters
local pdfverbose = lpdf.verbose
local pdfarray = lpdf.array
local factor = number.dimenfactors.bp
local f_value = formatters["\letterpercent.6N"]
local function boxvalue(n)
return pdfverbose(f_value(factor * n))
end
lpdf.addtopageattributes("TrimBox", pdfarray {
boxvalue(30),
boxvalue(30),
boxvalue(180),
boxvalue(267),})
\stopluacode
\to \aftereverypage
This code throws no errors, but unfortunately it also has no effect. What
am I doing wrong?
