Hi,
I need to make a figure with shaded areas and I found this code proposed by
Hans. Why does the definition of the r path that Hans proposed give the
same result as what I propose ?
Thank you.
Fabrice
\starttext
\startMPpage[offset=2pt]
path p, q, r ; pair z ;
p := unitsquare scaled 4cm ;
z := point 3.6 of p ;
q := z--urcorner p ;
r := z--urcorner p--lrcorner p--llcorner p--cycle ;
%r := q -- reverse bottomboundary p -- cycle ; definition of Hans
draw p ;
draw r numberstriped (.25,10,5) withcolor magenta ;
draw thetextext.llft("B", llcorner p) ;
draw thetextext.lrt ("C", lrcorner p) ;
draw thetextext.ulft("A", ulcorner p) ;
draw thetextext.urt ("D", urcorner p) ;
draw thetextext.lft ("M", z) ;

Look at the definition of bottomboundary in mp-tool.mpiv
Use whatever you prefer.
You might also be interested in the modification that I added to
label:
label.llft("B", p) ;
label.lrt ("C", p) ;
etc.
Alan
