image command in Metapost

image command in Metapost

[David Arnold]

All,

In:

   def hlingrid (expr Min, Max, Step, Length, Width) text t =
     image ( for i=Min step Step until Max+grid_eps :
	draw (origin--(Width,0)) shifted (0,i*(Length/Max)) t ;
       endfor ; ) ;
   enddef ;

What does the image command do? Where is it documented?

It executes a set of commands and creates an expression of
type "picture" from them. It is defined in the plain macros.

Cheers,
Taco
