how can I use framewidth in calculations
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! Thomas

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

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

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! Thomas

there is no need for \expandafter here as \dimexpr will expand what comes after it anyway ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

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 Wolfgang
