Using frames with metapost background in metapost

Using frames with metapost background in metapost

[Aditya Mahajan]

Hi,

I want to use a frame with metapost background to highlight some text 
inside metapost. But, the best that I can do is get metapost 
to typeset the code for the background, rather than execute it! Any ideas 
on a work around (in MkIV).

\startmode[error]
\defineoverlay[MP:background]
               [\useMPgraphic{MP:backgound}]

\startuseMPgraphic{MP:backgound}
     draw OverlayBox randomized 9pt withcolor blue;
\stopuseMPgraphic
\stopmode

\defineframed[boxframed][frame=on,background=MP:background]

% A frame defined with \defineframe does not work
% inside Metapost, so I prevent expansion.

\unexpanded\def\boxed#1{\boxframed{#1}}

\starttext

\boxed{Boxed in text}

\startMPcode
  draw textext("\boxed{boxed in metapost}") ;
%draw textext("\boxframed{boxed in metapost}") ;
\stopMPcode

\stoptext

Thanks,
Aditya

\starttext

\startMPcode
     picture p ; p := textext("boxed in metapost") ;
     draw p ;
     draw (boundingbox p) randomized 9pt withcolor blue;
\stopMPcode

\stoptext

for more complex cases use image as in

picture p ; p := image (
	draw this;
	drae that;
) ;

Thanks. I needed this for drawing fancy borders with boxes.mp. Using 
metapost to directly draw the frame is not as convinient as using \framed, 
but it does work.
