Maximum width of a caption
Hi, Is there any way to set the maximum width of a caption? I would like to make sure that no figure caption exceeds, say, 75% of text width. Here's an example of "bad behaviour" in the second figure: \starttext \reservefigure [width=5cm,height=2cm,frame=on][force] {Some very small figure with not too much text: OK} \input tufte This can hardly be distinguished from the main text: \reservefigure [width=\textwidth,height=.2\textwidth,frame=on][force] {\input tufte} \input tufte Desired behaviour: \placefigure[force]{\input tufte} {\hbox to .75\textwidth{\hss\framed[width=\textwidth,height=.2\textwidth]{}\hss}} \input tufte \stoptext I've seen an option maxwidth, but only in connection to \externalfigure[...][maxwidth=...]. I can cheat as on the third figure above, but that seems like an ugly approach to me. Thank you, Mojca

Thank you very much. The patch that you sent me for strc-flt.mkvi seems to work as expected on a long document with many figures. The only exception are one-liners. The following creates a caption that extends to almost the whole text width: \placefigure % Why are there two spaces between "dummy" and "text"? {Some \dorecurse{7}{dummy } text} {\externalfigure[dummy][width=\textwidth,height=.2\textwidth]} As soon as slightly more text is added, it shrinks to the desired text width. (But then again I'm not sure if that is a bug or a feature ;) Mojca

oneliners have a separate branch
