Hi Hans,
Thank you for the new upload.
The teaser examples work fine, many thanks !
I have a question though: how can one center within a page a text, for example
typeset in a circular shape? I tried with \startalignment, and also with
\startplacefigure but none of these gives a centered circular shape.
Also I noticed that if one removes the comment at the end of
\startshapedparagraph, or add a blank line after that, then the circular shape
is destroyed: is this on purpose ?
Best regards: Otared
% begin example-circular-shape.tex
\starttext
%\startuseMPgraphic{circle}
% lmt_parshape [
% path = fullcircle scaled 136mm,
% offset = 2mm,
% bottomskip = - 1.5LineHeight,
% ] ;
%\stopuseMPgraphic
\startuseMPgraphic{circleBis}
lmt_parshape [
path = fullcircle scaled 90mm,
offset = 2mm,
bottomskip = - 1.5LineHeight,
] ;
\stopuseMPgraphic
\startalignment[middle]
%\startplacefigure[align=middle,number=no]
\start
\startshapedparagraph[list=circle,mp=circleBis,repeat=yes,method=repeat]%
\setupalign[verytolerant,stretch,last]
\dontcomplain
{\darkred \samplefile{thuan}}
\stopshapedparagraph
\stop
%\stopplacefigure
\stopalignment
\stoptext
% end example-circular-shape.tex
