Subject: Re: Metafun: how to draw a straight line past the end points

Hi Aditya,

Thanks for the alternative method, which comes handy if one wishes to extend the straight line by a different amount at either end:

\starttext
\startMPcode
   z1 = (1cm,3cm) ;
   z2 = (5cm, 9cm) ;
   z3 = 1cm * dir(angle (z2 - z1)) shifted z2 ;
   z4 = -.5cm*dir(angle(z2 - z1)) shifted z1 ;
   draw z1 -- z3 ; 
   draw z4 -- z1 ;
   draw z1 -- z2 withcolor red ;
\stopMPcode
\stoptext

Best regards: Otared
