Re: [NTG-context] How to get randomly coloured text in metapost?

11 May 2010

      ...
numeric r, g, b ;
r := uniformdeviate 1 ;
g := uniformdeviate 1 ;
b := uniformdeviate 1 ;
textext("\colored[r=" & r & ",g=" & g & ",b=" & b & "]{Test}")
Thanks for this snipped, Hans. It looks promising, but I get the
following compile error:
!mplib          : mp terminal: >> "\colored [r="
    >> 0.74464
    ! Not implemented: (string)&(known numeric).
    <to be read again> 

I used the following code:

\starttext
\startuseMPgraphic {1}

numeric r, g, b ;
r := uniformdeviate 1 ;
g := uniformdeviate 1 ;
b := uniformdeviate 1 ;

label(textext("\colored[r=" & r & ",g=" & g & ",b=" & b & "]{Test}"),
origin);

\stopuseMPgraphic
\useMPgraphic {1}
\stoptext
