Re: [NTG-context] How to make floats extend into the outer margin

24 Jul 2014

      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.

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
