Hi,
I have a broken flow cell connection in this minimal example. The broken
flow cell is only triggered when drawn within a subsection with an overlay.
The logic to create the underlined subsection is by the way copied from the
metafun manual source. I do not have the slightest clue what is going wrong
in this example. Thanks for ideas.
Best, Bernd
\usemodule[chart]
\startuniqueMPgraphic{SectionUnderline}
path p;
p:= unitsquare xscaled OverlayWidth yscaled OverlayHeight;
draw llcorner p -- lrcorner p;
setbounds currentpicture to p;
\stopuniqueMPgraphic
\defineoverlay[SectionUnderline][\uniqueMPgraphic{SectionUnderline}]
\starttexdefinition unexpanded ChapterCommand #1#2
\framed [background=SectionUnderline] {#2}
\stoptexdefinition
