== \defineMPinstance MetaFun is ConTeXt extension the [[MetaPost]] language. It provides a tight integration of both TeX and \setupMPinstance ==[[MetaPost]]. MetaPost can used behind the scenes for some graphic trickery. This integration is also helpful for drawing figures in MetaPost and use them in the document.

{{cmd'''THE [[manual:metafun-p.pdf|defineMPinstance}} and {{cmdMetaFun manual]]''', also available in a [[manual:metafun-s.pdf|setupMPinstance}} can be used to set up MetaPost invocations with particular features. One use case could be to select a sans serif font for all MetaPostlabelsscreen version]].

{{cmd|startMPenvironment}} is a Don'''deprecated''' evironment in which one could place settings that one only wanted to apply in the MetaPost environment, but not in t miss the document itselfillustrations at 100% MetaFun page [https://art-aleatoire. One should use {{cmd|defineMPinstance}} and {{cmd|setupMPinstance}}, insteadcom art-aleatoire].

Inside {{cmd|startMPinclusions}} one can specify MetaPost files to ''input'', and also define MetaPost functionsThis page is a brief overview of some of the commonly used commands.

== \startuseMPgraphic and \useMPgraphic =System Overview =

{{cmd[[File:MetaPost in Context v2.png|startuseMPgraphic}}defines a piece of graphics code that is processed anew every time the graphic is placed with {{cmd|useMPgraphic}}.300px]]

=Commonly used commands = \startreusableMPgraphic and \reuseMPgraphic ==For graphics that are the same every time, it is better to use {{cmd|startreusableMPgraphic}}: the graphic is compiled only once, and the one resulting picture can be placed at various points with {{cmd|reuseMPgraphic}}.

When reusing a graphic is not important, you can simply use ; {{cmd|startMPcodestartMPinclusions}}: Inside, one can specify MetaPost files to ''input'', and also define MetaPost functions.

; {{cmd|startMPpagestartMPcode}} produces : When reusing a page a containing MetaPost graphic. The page is just large enough to contain the graphic. The resulting pdf is self-contained (it has all the fonts embedded) This is useful if not important, you want to send the figure to a coauthor or a journalcan simply use {{cmd|startMPcode}}.

; {{cmd|startstaticMPfigure}}, {{cmd|usestaticMPfigure}}: The {{cmd|startuseMPgraphic}} series of commands were designed for using MetaPost for drawing fancy frames and backgrounds and not for using <i>stand-alone</i> graphics for a document. {{cmd|startstaticMPfigure}} creates a separate pdf file containing the graphic. This pdf can be included in the document using {{cmd|usestaticMPfigure}}. ConTeXt is clever enough to recompile the resulting MetaPost file only if something inside the {{cmd|startstaticMPfigure}} has changed.
