Sorry, I misunderstood the question. Here is a solution (perhaps there is a simpler solution !):

\startMPpage
	picture TheImage ; 
	TheImage := image(
		draw externalfigure "cow.pdf";
		);
	TheImage := TheImage shifted -center(TheImage);
	draw TheImage ;
	draw (0,0) withpen pencircle scaled .2in withcolor magenta ;
\stopMPpage
