[NTG-context] framed float with offset

2011-01-01 Thread Sanjoy Mahajan 
Is there a way to have figures placed on a slightly larger colored
background and then have paragraph text flow around the enlarged area?

I tried the following (using ver 2009.11.26 16:28 MKII):

\setupcolors[state=start]
\starttext
\placefigure[right,none]{}%
{\externalfigure[sample/cow.pdf]%
[scale=500,
 frame=on, frameoffset=20pt,
 framecolor=black,
 background=color, backgroundcolor=lightgray,
 backgroundoffset=20pt]}

\input knuth
\stoptext

But the frame and background bleed into the text.

I tried wrapping the externalfigure in a \framed, and also wrapping that
in an \vbox or an \hbox (desperate measures, I admit).  But somehow the
\placefigure always knew exactly the size of the cow itself and used
only that information, rather than the size of the enlarged background.

Any suggestions appreciated.  (I'd wikify in the framed section.)

Hello Sanjoy,

\starttext
\placefigure[right]{Problem: offset=20pt ignored here!}
{\externalfigure[sample/cow.pdf]
  [scale=500, frame=on, offset=20pt,
background=color, backgroundcolor=lightgray]}
\input knuth

\placefigure[right]{This is ok!}{\framed[offset=20pt, background=color,
backgroundcolor=lightgray]{\externalfigure[sample/cow.pdf][scale=500]}}
\input knuth
\stoptext

Peter,

 \placefigure[right]{This is ok!}{\framed[offset=20pt,
 background=color,
 backgroundcolor=lightgray]{\externalfigure[sample/cow.pdf][scale=500]}}
 \input knuth


Ah, I had tried almost that recipe (of wrapping the \externalfigure in a
\framed) but had used backgroundoffset and frameoffset.  Yours works
perfectly.  I wikified the recipe at
