Hi Mikael,
here's a very simple mwe for the label(textext()) issue. On page 1, the text
"Word 1" should be drawn in position z1. On page 2, the same text in the same
position should be visible, and the text "Mot 2" in position p2 should be
added. And so on.
\startMPinclusions
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);
p1:=image(
label(textext("Word 1"), z1);
);
p2:=image(
label(textext("Mot 2"), z2);
);
p3:=image(
label(textext("Parola 3"), z3);
);
\stopMPinclusions
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="&decimal(currentime)) scaled 2 shifted(0,2in) withcolor
magenta ;
for k=1 upto currentime: draw p[k]; endfor
setbounds currentpicture to TheFrame ;
desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );
\stopMPpage
}
\stoptext
