or in metapost:

     draw image(
       for i = (0,0), (7.8,0), (7.2,72), (4.8,168), (4.9,249) :
         draw fullcircle
           shifted (xpart i, 0)
           rotated (ypart i)
           withpen pencircle scaled .45
           withcolor (1,1,0) ;
       endfor ; ) scaled 1.417 ;

i wonder if it makes sense to add a such a feature to texexec so that one 
can eurionize a pdf doc
