the fit assumes operating on a page not in a box; an alternative is: \framed[width=5cm,height4cm] {\externalfigure[mill.png][maxwidth=4cm,maxheight=5cm,width=10cm]} i.e. setting the maximum values > Anyway, I've found a temporary solutin to my problem by > using a very large value of scale=, coupled with appropriate > maxwidth and maxheight values. > -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
