Hi Hans,
The tip you gave me (wandering spaces), worked for the previous
example, the one where the overlay was attached to the background of
the "paper".
For the other example, where the overlay is attached to the background
of a "\framed", I haven't been able to make it work. The extra spaces
there, were in fact added "during the mail process" but weren't in my
file.
I put the file that doesn't work in "attached files", so there are no
risk it collects extra spaces.
There is probably an obvious and silly mistake but I can't find it:
for me it's quite similar to the examples in metafun-p.pdf, p. 127:
"\framed[background=demo circle]{This text is overlayed.}", but mine
refuses to work.
you need to anchor the graphic:
\starttext
\defineoverlay[my fourth overlay][\positionoverlay{my backgraphics}]
\startpositionoverlay{my backgraphics}
\setMPpositiongraphic{three}{mypos:circle}{mypos:circleradius=1cm,mypos:circlecolor=red}
\setMPpositiongraphic{three}{mypos:circle}{mypos:circleradius=.5cm,mypos:circlecolor=green}
\stoppositionoverlay
\startMPinclusions
if unknown context_apos : input mp-apos.mpiv ; fi ;
if unknown context_abck : input mp-abck.mpiv ; fi ;
\stopMPinclusions
\startMPpositiongraphic{mypos:circle}
numeric x, y, w, h, d, radius;
color c;
path p ;
x = \MPx{\MPvar{self}};
y = \MPy{\MPvar{self}};
w = \MPw{\MPvar{self}};
radius = \MPvar{mypos:circleradius};
c = \MPvar{mypos:circlecolor};
p = (x+w/2+radius,y)..(x+w/2,y+radius)..(x+w/2-radius,y)
..(x+w/2,y-radius)..cycle;
drawarrow p withpen pencircle scaled 2pt withcolor c;
anchor_box(\MPanchor{\MPvar{self}}) ;
\stopMPpositiongraphic
\framed [background=my fourth overlay,align=middle,width=7cm] {have
attached it: \hpos{three}{{\em here}}, the}
\stoptext
