Hello,
I notice a strange behavior of the macro numberstriped ( ).
Thanks.

Hi Hans,
Thank you for this solution which is an approach that I did not know.
Fabrice

PS : What is the exact meaning of the word "blobs" because my English is
average ?

in order to get 'lines' you need to fill the two opposing corners with 
"blobs of ink"

Otherwise, a BLOB is a “binary large object”, e.g. if you save image 
data to a database.

Hi Hans,
When the rectangles are not identical, how to have the same type of
hatching in both ?

Hi,
Initially, there was a bug with maro numberstriped() and Hans suggested
another sensible approach to me, but you don't get the same shape of the
hatches depending on the dimensions of the squares.
Your solution works perfectly but I'm trying to understand the action of
the parameters:
the first ?
the second represents the angle in degrees that the segments make
the third represents the gap between two segments
Thanks
Fabrice

some unexpected side effect show up when the unitsquare is xyscaled to a 
rectangle like (2.5cm,1cm)
it seems related to the angle chosen

e.g.



\startMPcode

path p, q, r, b ;
p  := unitsquare xyscaled (4cm,4cm) ;
q := unitsquare xyscaled (1cm,1cm) shifted(0,3cm) ;
r := unitsquare xyscaled (2.5cm,1cm) shifted(1cm,3cm) ;
b := unitsquare xyscaled (3cm,3cm) shifted(1cm,0) ;

draw r anglestriped (1,35,2) withcolor red;
draw q anglestriped (1,35,2) withcolor green;
draw b anglestriped (1,35,2) withcolor cyan;
draw p;
draw q;
draw b;
draw r;

label.llft("D", p) ;
label.lrt("C", p) ;
label.ulft("A", p) ;
label.urt("B", p) ;
label.urt("P", lrcorner r) ;
label.lft("Q", llcorner r) ;
label.top("M", urcorner r) ;

Not only, it is also true with the code below :

\startMPcode
    path p, q, r, b ;
    p  := unitsquare xyscaled (4cm,4cm) ;
    z[0] = (2cm,0cm) ;
    z[1] = (2cm,4cm) ;
    z[2] = (0cm,2cm) ;
    q := llcorner p--z[0]--z[1]--z[2]--cycle ;
    r := unitsquare xyscaled (1cm,1cm) shifted(0,3cm) ;
    b := (0cm,0cm) -- lrcorner r -- lrcorner p -- cycle;

    draw r anglestriped (1,45,2) withcolor green;
    draw b anglestriped (1,45,2) withcolor green;

    draw b withcolor darkgreen;
    draw r withcolor darkgreen;
    draw p;

    label.llft("B", p) ;
    label.lrt("C", p) ;
    label.ulft("A", p) ;
    label.urt("D", p) ;
    label.urt("F", lrcorner r) ;
    label.lft("E", llcorner r) ;

for that you can patch mp-tool.mpxl (l 676):

         maximum := max (xpart llcorner mask, xpart urcorner mask, ypart 
llcorner mask, ypart urcorner mask) ;
         minimum := min (xpart llcorner mask, xpart urcorner mask, ypart 
llcorner mask, ypart urcorner mask) ;
         % a hack:
maximum := maximum + max(xpart urcorner shape, ypart urcorner shape);
minimum := minimum - max(xpart urcorner shape, ypart urcorner shape);

a bit overkill but it seems to work

I just tried but I got an empty file...
Do we agree that I have to replace the two lines with the other two ?
Regarding what you proposed, how to get the same type of hatching in both
figures ?

 \startMPcode
    path p, q, r, b ;
    p  := unitsquare xyscaled (4cm,4cm) ;
    z[0] = (2cm,0cm) ;
    z[1] = (2cm,4cm) ;
    z[2] = (0cm,2cm) ;
    q := llcorner p--z[0]--z[1]--z[2]--cycle ;
    r := unitsquare xyscaled (1cm,1cm) shifted(0,3cm) ;
    b := (0cm,0cm) -- lrcorner r -- lrcorner p -- cycle;

     draw r
         withpattern image (
             draw (llcorner unitsquare -- urcorner unitsquare) scaled 5mm ;
             % how to get the corner dots
         )
         withpatternscale 1/4
         withpen pencircle scaled 1bp
         withcolor green
     ;
    draw b
         withpattern image (
             draw (llcorner unitsquare -- urcorner unitsquare) scaled 5mm ;
             % how to get the corner dots
         )
         withpatternscale 1/16
         withpen pencircle scaled 1bp
         withcolor green
     ;


    draw b  withpen pencircle scaled 1bp  withcolor darkgreen;
    draw r  withpen pencircle scaled 1bp  withcolor darkgreen;
    draw p;

    label.llft("B", p) ;
    label.lrt("C", p) ;
    label.ulft("A", p) ;
    label.urt("D", p) ;
    label.urt("F", lrcorner r) ;
    label.lft("E", llcorner r) ;
    label.top("G", urcorner r) ;

  \stopMPcode

no, we disagree here; add them after the min/max lines

Ok, it works very well. Without wanting to insist, how to have the same
hatching with two different figures ?
Thanks.

Oh, OK, here it goes. Hans will probably rename things if he adds this.

withpen currentpen ;
) ;
thestripe := thestripe shifted center boundingbox p ;
thestripe := thestripe rotatedaround(center boundingbox p, a) ;
clip thestripe to p ;
thestripe
enddef ;


path p ; p := fullcircle scaled 3cm && (unitsquare scaled 2cm shifted
