On Windows, I got it working again with current Context (20180404) and current luatex from win32tex (1.07 development ID 6686) On linux-armhf I did a fresh "./first-setup.sh --engine=luatex" and got: mtx-context | ConTeXt Process Management 1.02 mtx-context | mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2018.09.30 19:32 and: This is LuaTeX, Version 1.09.0 (TeX Live 2019/dev) The LuaTeX team is Hans Hagen, Hartmut Henkel, Taco Hoekwater, Luigi Scarso.

Hi Hans, hi all,

I think, that recent context has a problem with scaling included pdf files. My minimal file:

\startMPpage draw externalfigure "cow.pdf" ; \stopMPpage

The resulting pdf is, as the original, 97x70.6 mm, all ok.

If I try to scale to the original size, i get arithmetic overflow error.

\startMPpage draw externalfigure "cow.pdf" xscaled 97mm yscaled 70.6mm ; \stopMPpage

Whe i scale it down, the pdf gets really big.

\startMPpage draw externalfigure "cow.pdf" xscaled 27.5mm yscaled 20mm ; \stopMPpage

results in a pdf with width of 4.938,8 mm and height of 2.612,3 mm.

I tested with recent context and luatex under windows 64 and linux-armhf.

which context and luatex version ? Are you using experimental ? -- luigi

xsized was the solution. I wonder why xscaled worked for me for years. because we used a 1bp image at that time (was needed in two-pass approach) ... we don't have that limitation now (and 1bp is pretty inaccurate anyway)
