Using MPgraphics as externalfigures?
Hi All, I'm being a bit clueless about the MPgraphics again... I've got a pile of instructional graphics that will be used and reused in a project. My first try is/was an unwieldy buffer construction, but I'm sure there's a better way than \placefigure[here] [fig: 5 loop departed setup] {The start position for a 5-loop braid with departed loops} {\framed{\getbuffer[setup 5-loop basic]}} Come to think of it, is there another way of framing the incoming graphic? I don't want to include the frames in the MPcode as I may not always want them, but that \framed{\getbuffer} construction is downright ugly. I think the solution to my problem can be found somewhere in the \startreuseagleMPgraphic and \reuseMPgraphic, but I don't seem to be able to figure out the last bits... On the moment my MPgraphics have \startbuffer[g1] \startMPcode ... \stopMPcode \stopbuffer but that's probably an overkill... And I'd really prefer to have the graphic as just a pic so I can easily use them as external figures. Of course one option would be to pdf the MPgraphics and then to insert the pdf, but I'd prefer to skip that step. Any ideas of how to do this in a smart way? Preferably without having to go into the bowels of ConTeXt to get it done... Thank you, Mari

Read http://wiki.contextgarden.net/Metapost and 3.3 Integrated Graphics in the MetaFun Manual.

Hi Marco & al,

I was on http://wiki.contextgarden.net/Mpgraphic which I actually found for informative, but not quite enough for my "very dummy" level.
and 3.3 Integrated Graphics in the MetaFun Manual.
*This* was my missing link (and I was being pretty stupid). I dug the book out of my pile of ConTeXt papers and found exactly what I needed, at the end of chapter 3.3, pages 115-117 in my paper copy. To answer to myself (in case somebody else ever looks for this); At least in theory the key to the problem is to create a file somefile.mp, then write the MP code in the file beginfig{01} . . . endfig ; end . The whole file is used by \startMPrun input somefile ; \stopMPrun and the individual figure is available in the virtual file mprun.01. Thus it can be included with \externalfigure[mprun.01][width=0.5\textwidth] %etcetera Page 117 even has an example of exactly the type of combination I'm trying to achieve, so now it's just down to creating the graphic(s) file(s). As my braiding graphics come in groups (steps and variations, to be exact), this solution looks like a winner for now.
\defineframed [graphicframe] [frame=on,offset=none]
\define[1]\MPframed {\graphicframe{\useMPgraphic{#1}}}
\startuseMPgraphic{first} fill fullcircle scaled 2cm withcolor red; \stopuseMPgraphic
\startreusableMPgraphic{second} fill fullsquare rotated 45 scaled 2cm withcolor blue; \stopreusableMPgraphic
\startbuffer [third] fill fullsquare scaled 1cm withcolor green; \stopbuffer
\starttext \useMPgraphic{first} \reuseMPgraphic{second} \processMPbuffer [third] \MPframed{second} \stoptext
Thank you! I'll have to delve into this bit once the current almost-past-deadline project is done, looks like this'll take a bit of processing before it starts to make sense to me (my computer has no such problems...). Now, time for some recoding, thanks once more! Mari

(Untested code, but this should work) \startbuffer[figure 1] draw fullcircle scaled 1cm; \stopbuffer \startbuffer[frame] draw (bbox currentpicture) withcolor blue; \stopbuffer \processMPbuffer[figure 1, frame] Basically, you can concatinate various buffers in \processMPbuffer. Aditya
