A Metapost question

A Metapost question

[Vyatcheslav Yatskovsky]

Hello,

a) Can anyone explain me the practical difference between 
\startuseMPgraphic and \startreusableMPgraphic ? Both the former and the 
latter allow to place a picture few times.

b) Does anyone mind if I add "Using in ConTeXt" section to 
http://wiki.contextgarden.net/MetaPost ?

Regards,
Vyatcheslav

'reuse' makes smaller pdf files as graphics are only included once; so 
does 'unique' but it uses some heuristics to determine uniqueness

  Of course not, that's what the wiki is here for.

Sorry, already have found the answer to my question in MetaFun Manual 
(metafun-s).

A Metapost question

[Michal Kvasnicka]

Good noon.

I'm sorry that I bother you with an off-topic question, but I know here are 
many Metapost gurus.

I'd like to join two point (E1 and E2) having the same ypart 
(ypart(E1)=ypart(E2)) with the TeX underbrace sign. To do it I have to tell 
TeX (via btex ... etex?) the horizontal distance of the two points. Do you 
know how can I do it?

Many thanks,
M.K.

%%% snip-->
input TEX ;

pair E[] ; numeric XShift ;

XShift := 3cm ; E1 := (1,13) ; E2 := E1 shifted (XShift,0) ;

beginfig(1);
pickup pencircle scaled 2pt ;
draw E1 ; label.top("E1",E1);
draw E2 ; label.top("E2",E2);

labeloffset := 0 ;

label.bot(
  TEX("$\underbrace{\hbox to " &
  (decimal (xpart (E2-E1))) & "bp{}}$"), 0.5[E1,E2]) ;
endfig;

end
%%%<--snap

The example above is plain MP. Embedded in a ConTeXt document you
should better use the "textext" macro instead of the "TEX" macro from
TEX.mp.
