\startreusableMPgraphic

Syntax (autogenerated)

\startreusableMPgraphic{...}{...,...} ... \stopreusableMPgraphic
{...}name
{...,...}key


Syntax

\startreusableMPgraphic{...}
{...} name under which the graphic will be known

Description

Define code for a MetaPost graphic. The graphic is compiled once, and can be reused multiple times with \reuseMPgraphic.

Example

\def\mycolor{.625red}

\startreusableMPgraphic{name}
  fill fullcircle scaled 20pt withcolor \mycolor;
\stopreusableMPgraphic

red: \reuseMPgraphic{name}

\def\mycolor{.625blue}
blue: \reuseMPgraphic{name}

The command is generally not very suitable for defining an overlays that must vary in width:

\startreusableMPgraphic{beta}
	fill unitsquare
		xyscaled (\overlaywidth, \overlayheight)
                % `uniformdeviate 1` produces a random number between 0 and 1
		withcolor (uniformdeviate 1, uniformdeviate 1, uniformdeviate 1);
\stopreusableMPgraphic

\defineoverlay
	[beta]
	[\reuseMPgraphic{beta}]

\dontleavehmode
\framed[background=beta]{narrow} ...
\framed[background=beta]{mini} ...
\framed[background=beta]{rather wide}
