Description
Define code for a MetaPost graphic. The graphic can be placed in the document with \useMPgraphic, and will be recompiled every time it is placed.
If a custom MetaPost instance (defined with \defineMPinstance) should be used, the name of the graphic has to be preceded by the name of the MetaPost instance, with a double colon in between: \startuseMPgraphic{instancename::graphicname}.
Example
\def\mycolor{.625red} \defineMPinstance [myinstance] [metafun] \startuseMPgraphic{myinstance::name} fill fullcircle scaled 20pt withcolor \mycolor; \stopuseMPgraphic \startuseMPgraphic{name} fill fullcircle scaled 20pt withcolor \mycolor; \stopuseMPgraphic red: \useMPgraphic{name} red: \useMPgraphic{myinstance::name} \def\mycolor{.625blue} blue: \useMPgraphic{name}
The command is very nice for defining overlays that vary randomly:
\startuseMPgraphic{randomcolor} fill unitsquare xyscaled (\overlaywidth, \overlayheight) % `uniformdeviate 1` produces a random number between 0 and 1 withcolor (uniformdeviate 1, uniformdeviate 1, uniformdeviate 1); \stopuseMPgraphic \defineoverlay [beta] [\useMPgraphic{randomcolor}] \dontleavehmode \framed[background=beta]{randomcolor} \framed[background=beta]{randomcolor} \framed[background=beta]{rather wide}
