Commands with arguments with MetaPost

Commands with arguments with MetaPost

[Troy Henderson]

I would like to be able to do something like this

\def\foo#1{
    \startMPcode
        fill (0,0)--(598,0)--(598,50)--(0,50)--cycle withcolor green;
        label.rt(btex #1 etex),(50,25);
  \stopMPcode
}

and then use this in my ConTeXt document by

\foo{Some text}

However, my syntax seems to be incorrect, and I would appreciate any
help in fixing it.

Thanks,

Troy Henderson

\framed [frame=off,background=color,backgroundcolor=green,width=598,height=50]
	{Some text}

(Of course, you need to put correct dimensions for the width and height
and also set an offset.)

Untested, so the syntax may be not quite correct.

You might want to use
\setupframedtext
and
\startframedtext
\stopframedtext
if you will be doing this often.
There is probably also a way to define a named framed text.

Looks like a misplaced parenthesis:

       label.rt(btex #1 etex,(50,25));
