Thanks for the solution Pablo. It works well.
I wanted to add more pdfs (which also has many pages) and found it was easier for me to reason in the lua side of things. This is what I have at the moment:
\starttext
\startluacode
local function doc(fil)
return fil..[[.pdf]]
end
local function disppdf(fname)
n = 1
repeat
context.externalfigure({fname},{
page = n,
width = "200mm",
scale = "950"
})
n = n + 1
until n == context(context.noffigurepages)
end
local pdffiles = {"ass1", "ass2", "ass3", "ass4", "ass5", "ass6", "ass7", "ass8"}
for index=1,#pdffiles do
local f = doc(pdffiles[index])
context.getfiguredimensions({f})
disppdf(pdffiles[index])
end
\stopluacode
\stoptext
I didn’t know how to get an array (or indexed table or whatever you call it) in ConTeXt/Tex. My problem is now with context(context.noffigurepages). It doesn’t produce an integer so n is being compared to nil. Am I calling it wrong? All I want to do is call \noffigurepages from the lua side. Is there something I am missing?

Hello,
I am trying to put multiple PDF’s that were typeset differently into
one document without modifying the individual files themselves.

The problem is the original page numbers show and I’d prefer that it
did not. So I thought maybe I could clip all the page numbers from
every page (since they are all in the same position across all the
pages) but I don’t know how to do this with the \clip command. Any
ideas? I already tried using \input but it gives some weird output in
some places. It doesn’t have to use this method as long as it does
what I need it to do.
Hi Jethro,
it works using \clip with \externalfigure inside a loop (\dorecurse).
With \getfiguredimensions you get the number of pages of each PDF
document (\noffigurepages).
The following source both generates the source PDF document and the
imposed result with clipped pages (just to see a sample of the commands
mentioned above):
\startbuffer[newbuff]
\setuppapersize[A3]
\setupbodyfont[sans, 1200pt]
\starttext
\dorecurse{8}
{\startmakeup[page][pagestate=start, align=center, style=\bf]
\recurselevel
\stopmakeup}
\stoptext
\stopbuffer
\startmode[*first]
\savebuffer[newbuff][source_page.tex, prefix=no]
\executesystemcommand{context --purgeall source_page.tex}
\stopmode
\setuplayout[page]
\setuppapersize[A6][A4]
\setuppaper[nx=2, ny=2]
\setuparranging [XY]
\starttext
\startnotmode[*first]
\def\Doc{source_page.pdf}
\getfiguredimensions[\Doc]
\dorecurse{\noffigurepages}
{\clip[hoffset=96mm, voffset=136mm, width=105mm, height=148mm]
{\externalfigure[\Doc][page=\recurselevel]}}
\stopnotmode
\stoptext
Just in case it might help,
Pablo
