Hi,
Can you help me with the two examples below, and also tell me how I
could have found out myself when it should have worked and when it
shouldn't: because until now, it is a mix of wild guess and poor trial
and error.
%%%%%% First example %%%%%%%
\starttext
%% This example doesn't work anymore if I comment the
%% indicated line below.
\defineoverlay[my first overlay][\uniqueMPgraphic{first demo}]
\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
\setupbackgrounds[paper][background={
my first overlay, %% Doesn't work anymore if I comment this line.
my fourth overlay}]
% These two lines can be removed without consequences
\startuniqueMPgraphic{first demo}
\stopuniqueMPgraphic
\startMPpositiongraphic{mypos:circle}
% absolute coordinates relative to paper by default?
numeric x, y, w, h, d, radius;
x = \MPx{\MPvar{self}};
y = \MPy{\MPvar{self}};
w = \MPw{\MPvar{self}};
radius = \MPvar{mypos:circleradius};
color c;
c = \MPvar{mypos:circlecolor};
path p ;
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;
\stopMPpositiongraphic

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%% Second example %%%%%%%%

%% The overlay is attached to the backgound of a framed instead of to the
%% background of the page.
\defineoverlay[my first overlay][\uniqueMPgraphic{first demo}]
\defineoverlay[my fourth overlay][\positionoverlay{my backgraphics}]

so that is effectively background={ my first overlay, my fourth overlay}
spaces after , are gobbled so if you want to comment things like that do
this
\setupbackgrounds[paper][background={%
my first overlay,%
my fourth overlay%
}]
now you can comment one of both lines

here
background=my first overlay
and
my fourth overlay
a key without value
so: be careful with spaces and commas

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.
Chris

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
