Bear with me, I still got no experience in MetaPost…
I’m trying to place a pixel image on a MP page.
According to the MetaFun manual this should work:
\startMPpage draw externalfigure "mill.png" scaled 5cm shifted (-6cm,0) ; \stopMPpage
And it works with mill.png (copied into my test dir), but with none of my other PNGs, I always get
! Arithmetic overflow. <*> ...xternalfigure "dodo.png" scaled 5cm shifted (-6cm,0) ; ; Uh, oh. A little while ago one of the quantities that I was computing got too large, so I'm afraid your answers will be somewhat askew. You'll probably have to adopt different tactics next time. But I shall try to carry on anyway.

1 \startMPpage
[instance=doublefun] will bump metapost into doublemode
2 draw externalfigure "dodo.png" scaled 5cm shifted (-6cm,0) ; 3 >> \stopMPpage 4
The same image file works with
\starttext \externalfigure[dodo][height=8cm] \stoptext
What’s wrong?
