Hi,
Actually, this is a bug report. If you try to include a pdf with a large
page size:
\starttext
\externalfigure[plankaart]
\stoptext
chances are that you get an error message like this:
! Dimension too large.
<recently read> \hsize
\setraggedness ...yphenpenalty \dimexpr 2.8\hsize
/\dimexpr #1\relax
\relax ...
\raggedcenter ...spac_align_set_raggedness_middle
\raggedstatus
\plustwo \at...
\next ...ght \pack_framed_do_setups \raggedcenter
\vss \bgroup
\localbegstru...
\grph_include_finalize ...tedexternalfigureframed
{\vfilll \box
\foundextern...
\grph_include_place ...ode \grph_include_finalize
\fi \ctxlua
{figures.pop()...
...
l.2 \externalfigure[plankaart]
It seems that \externalfigure forces execution of \raggedcenter, and if
your PDF's page is large enough, that then fails.
There is, in fact, a workaroud:
\starttext
{\setupalign[nothyphenated]\externalfigure[plankaart]}
\stoptext
but that looks totally bizarre. Hans, can you find a way to fix this
properly?
Best wishes,
Taco

PS: What would break if we extended dimens to 64/63 bit in LuaTeX?

works ok here (which surprises me)
(but as martin says: going 64 bit would be nice)

Yes.

Some poor programmer's head ;)
Seriously, the actual implementation would be quite a lot of work.
There are definite places in the backend where a 64-bit number
would be a no-no, and these have to be captured somewhere.
And then there is the lua_Number that is a double, so it cannot fit
a full 64-bit number without precision loss, etc.
Best wishes,
Taco
