ConTeXT provides a tight integration of TeX and [[MetapostMetaPost]]. 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. This page is a brief overview of some of the commonly used commands.
== \defineMPinstance and \setupMPinstance ==
{{cmd|defineMPinstance}} and {{cmd|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 MetaPost
labels.
=== \startMPenvironment ===
{{cmd|startMPenvironment}} is a '''deprecated''' evironment in which one could place settings that one only wanted to apply in the MetaPost environment, but not in the document itself. One should use {{cmd|defineMPinstance}} and {{cmd|setupMPinstance}}, instead.
== \startMPinclusions ==
Inside {{cmd|startMPinclusions}} one can specify MetaPost files to ''input'', and also define MetaPost functions.
== \startuseMPgraphic and \useMPgraphic ==
{{cmd|startuseMPgraphic}}defines a piece of graphics code that is processed anew every time the graphic is placed with {{cmd|useMPgraphic}}.
== \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}}.
== \startMPcode ==
When reusing a graphic is not important, you can simply use {{cmd|startMPcode}}.
== \startMPpage ==
{{cmd|startMPpage}} produces 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 you want to send the figure to a coauthor or a journal.
== \startstaticMPfigure ==
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.
