Hi Graham,

I don't think this is supposed to happen, but please send me the pdf
for a closer look and, if possible, a source to go with it that uses a
lua library that is available to me. I am on linux, but lxp should
work for me as well. I can even try to run the test under wine.
I've looked at your file, and it is not related to external
libraries nor the luatex extensions at all: The problem is the
\immediate\pdfximage.
You can get the exact same problem in pdftex with this input:
\pdfoutput=1
\immediate\pdfximage width 0.5\hsize {./cow.pdf}
\pdfrefximage\pdflastximage
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\input knuth
\bye
In both cases, the problem can be fixed by adding a \hbox around
the \pdfrefximage. But now I have a question for Hartmut: is this
supposed to happen?
definitely looks like a bug to me
\setuppapersize[A4][A1] \setuplayout[location=middle,marking=on]
\starttext
\immediate\pdfximage width 0.5\hsize {./cow.pdf}
\dorecurse {3}{\pdfrefximage\pdflastximage}
\dorecurse{10}{\the\pagetotal\input knuth \par}
\stoptext
the ref'd image whatsit is added to the mvl but the height is not added
to pagetotal (at least that's what it looks like) due the fact that no
paragraph is started
i assume that this bug went unnoticed as macropackages put such material
normally in a box
i'm not sure if it's the parbuilder or the page builder .. another test:
\dorecurse {5}{\pdfrefximage\pdflastximage x\par}
(i can do some more testing tommorrow)
