buffers inside startMPpage

buffers inside startMPpage

[Jan Willem Flamma]

Dear list members,

I create all my MetaFun drawings in a separate environment file where each individual drawing sits inside a start/stopbuffer. This allows me to easily use those drawings in all my documents using \processMPbuffer[name]. Works just fine.

However, I also wish to have all the drawing available in a pdf file (each drawing on a separate page). This allows me to split the pdf and use the drawing elsewhere (e.g. in a Powerpoint) or include page(s) from the pdf in another document.

The below MWE represent my MetaFun drawings file.
The idea is that by uncommenting the \enablemode[makepdf] I can create the pdf file with drawings. It seems however that startMPpage does not accept buffers (I also tried processbuffer and processMPbuffer).

Is it possible to somehow make this work?

Thanks and regards,
Jan Willem Flamma


%\enablemode[makepdf]

\startbuffer[fig1]
  draw fullcircle scaled 2cm withcolor red ;
\stopbuffer

\startbuffer[fig2]
  draw unitsquare scaled 2cm withcolor red ;
\stopbuffer


\startmode[makepdf]
  \starttext
	\startMPpage
	  \getbuffer[fig1]
	\stopMPpage
	
	\startMPpage
	  \getbuffer[fig2]
	\stopMPpage
  \stoptext
\stopmode

You can use

     \startTEXpage
         \processMPbuffer[…]
     \stopTEXpage

but loading a buffer in MPpage doesn’t work because the content of the 
environment
is just passed to MetaPost and buffers can’t be loaded inside MetaPost 
code unless
Hans adds a function for this, e.g.

     \startMPcode
         buffer("mybuffer")
     \stopMPcode

Thank you Wolfgang.

This suits my needs just fine.

Kind regards,
