PG> why did you use "counterclockwise simplified..." ? What is this?
I used that to make sure that p didn't have extra points
(simplified) and went in a specific direction (counterclockwise);
anyway, I rewrote my code:
===
\starttext
\setupcolors[state=start]
\definetextbackground[gb][state=start]
\startuseMPgraphic{mpos:par:columnset}
pair urc, ulc, llc, lrc ; % corners
path urcp, ulcp, llcp, lrcp ; % paths
path q ;
cornerradius := 5pt ;
offset := 7.5pt ;
color framecolor, backgroundcolor ;
pen framepen ;
framecolor := red ;
framepen := pensquare rotated 45 ;
framethickness := 2pt ;
backgroundcolor := lightgray ;
for i := 1 upto nofmultipars :
urc := urcorner multipars[i] + (offset, offset) ;
ulc := ulcorner multipars[i] + (-offset, offset) ;
llc := llcorner multipars[i] + (-offset, -offset) ;
lrc := lrcorner multipars[i] + (offset, -offset) ;
ulcp := quartercircle
rotated 90
scaled (2*cornerradius)
shifted (ulc + (cornerradius, -cornerradius)) ;
urcp := quartercircle
scaled (2*cornerradius)
shifted (urc + (-cornerradius, -cornerradius)) ;
llcp := quartercircle
rotated 180
scaled (2*cornerradius)
shifted (llc + (cornerradius, cornerradius)) ;
lrcp := quartercircle
rotated -90
scaled (2*cornerradius)
shifted (lrc + (-cornerradius, cornerradius)) ;
if multilocs[i] = 1 : % top
q := lrc -- urcp -- ulcp -- llc ;
fill q--cycle
withcolor backgroundcolor ;
draw q
withcolor framecolor
withpen framepen scaled framethickness ;
elseif multilocs[i] = 2 :
fill llc -- lrc -- urc -- ulc -- cycle
withcolor backgroundcolor ;
draw ulc -- llc
withcolor framecolor
withpen framepen scaled framethickness ;
draw lrc -- urc
withcolor framecolor
withpen framepen scaled framethickness ;
else:
q := ulc -- llcp -- lrcp -- urc ;
fill q--cycle
withcolor backgroundcolor ;
draw q
withcolor framecolor
withpen framepen scaled framethickness ;
fi
endfor ;
\stopuseMPgraphic
\starttextbackground[gb]
\input tufte
\stoptextbackground
\blank[2*big]
\starttextbackground[gb]
\dorecurse{5}{\input tufte \par}
\stoptextbackground
\blank \input tufte
\stoptext
===
Now the only thing we need is a way to know when the background is
split and when it's not. Hans?
