Hello,
I assume others might have need for this, so it might be a good idea to
put this into the
core with a name of something like \widefigure or \ placewidefigure!
Just, a thought!
regards
Keith.

Dear list,
I have some big-width floats, and want them to span the regular text
width plus the outer margin.  I can position them manually with \kern.
Is there a way to make them automatically extend into the outer
margin?  I have tried different options for location=... without
success.
{snip, snip}
\starttext

\startplacefigure
     \framed[width=.8\textwidth,framecolor=red]{one}
\stopplacefigure

\setupfloat[figure][location=flushleft]

\startplacefigure
     \framed[width=1.2\textwidth,framecolor=blue]{two}
\stopplacefigure

\stoptext
...

You can use the command key for \setupfloat to apply a macro to the
finished content of the float.
The purpose of this macro is to save the content and compare the width
to the width of the text are,
when the figure is wider then the available space use the \leftaligned
or \rightaligned commands
to let the content protrude to the outer margins.
\setuppagenumbering[alternative=doublesided]
\setuplayout[backspace=4cm,width=12cm]
\definemeasure[Widefigure][\textwidth+\rightmargindistance+\rightmarginwidth]
\setupfloat[figure][command=\FigureCommand]
\define\FigureCommand
 {\dowithnextbox
    {\signalrightpage
     \ifdim\nextboxwd>\textwidth
       \doifrightpageelse{\leftaligned{\flushnextbox}}{\rightaligned{\flushnextbox}}%
     \else
       \midaligned{\flushnextbox}%
     \fi}
    \hbox}
\showframe
\starttext
\startplacefigure
\framed[width=.8\textwidth,framecolor=red]{Left margin}
\stopplacefigure
\page
\startplacefigure
\framed[width=\measure{Widefigure},framecolor=red]{Left margin}
\stopplacefigure
\input knuth
\page
\startplacefigure
\framed[width=\measure{Widefigure},framecolor=red]{Right margin}
\stopplacefigure
\stoptext
