Thank you, that is exactly what I needed! I'll see if I can find some
more information about \dimexpr now!

\framed[width=7cm]{\externalfigure[cow][width=0.75\expandafter\dimexpr\framedparameter{width}]}
works for me

Ooh, expansion, my old nemesis, strikes again! Thanks, that works too -
this is one of the many aspects of TeX that I have never really grasped...
Thanks!

\framed[width=7cm]{\externalfigure[cow][width=0.75\expandafter\dimexpr\framedparameter{width}]}
there is no need for \expandafter here as \dimexpr will expand what
comes after it anyway

Hi all,
maybe I'm overlooking something obvious, but...: when I have a figure, I can
calculate its width dependent on the page width, and it will adapt:
\starttext
\externalfigure[cow][width=0.6\textwidth]
\stoptext
But is there a method for similar calculations inside a frame? Here's what I
tried, but it doesn't give the expected result (the image is much smaller
than expected):
\starttext
\framed[width=7cm]{\externalfigure[cow][width=\the\dimexpr0.9\framedparameter{width}\relax]}
\stoptext
Thanks for any pointers!
\starttext
\framed[width=7cm]{\externalfigure[cow][width=0.5\dimexpr\framedwidth\relax]}

When you set a value for the align-key the \framed command uses a \vbox for the
content and you can use \hsize for the width.
\starttext
\framed[width=7cm,align=middle]{\externalfigure[cow][width=0.9\hsize]}
\stoptext
