Hi!
How to scale an image in MetaPost, maintaining the aspect ratio
(without specifying the height explicitly)?
Example:
\setupexternalfigures [location=default]
\starttext
   \externalfigure [cow][width=5cm]
\startMPcode
     draw externalfigure "cow" scaled 5cm;
   \stopMPcode
\stoptext
it's all in the metafun manual
No doubts about that. It's more a matter of knowing what to search
for.
...
xsized 5cm
I tried it, same result - square image:

  draw externalfigure "cow" xsized 5cm;

As Alan mentioned including the image with textext() works. Not as
elegant, but it gets the job done.
