Hi all,
I'm sure there must be a solution for this, but I haven't been able to
find it yet: I want my chapter titles typeset in a sort of frame which
will span the entire page, not only the text area, so I guess the
easiest way to do that would be a page background. How can I set up a
background that will appear only on the title page, in addition to the
regular background? Bonus question: I also want the color schemes of
both backgrounds to be different in every chapter, so the solution
should make this possible. The example is a bit silly, but it shows what
I'm looking for, I hope.
Thanks, and all best
Thomas

Hi,
You know the price you have to pay: wikifying ..
\setuplayout

\startMPinclusions
numeric MyTitlePageDone[] ;

StartPage ;
fill
(topboundary Page --cycle) enlarged(0,5mm) shifted (0,-5mm)
withcolor
\MPcolor{color:background:\namedstructureuservariable{chapter}{mycolor}} ;
StopPage ;
\stopuseMPgraphic
\defineoverlay
[background:normal]
[\useMPgraphic{background:normal}]
\startuseMPgraphic{background:title}
if unknown
MyTitlePageDone.\namedstructureuservariable{chapter}{mycolor} :
StartPage ;
fill
((topboundary Page --cycle) enlarged(0,5mm)) shifted
(0,-20mm)
withcolor
\MPcolor{color:title:\namedstructureuservariable{chapter}{mycolor}} ;
StopPage ;
MyTitlePageDone.\namedstructureuservariable{chapter}{mycolor}

fi ;
\stopuseMPgraphic
\defineoverlay
[background:title]
[\useMPgraphic{background:title}]
\setupbackgrounds
[page]
[background={background:normal,background:title}] % could be drawn in
one go
\definecolor [color:title:one] [r=0.86,g=0.88,b=0.76]
\definecolor [color:background:one] [.9(color:title:one)]
\definecolor [color:title:two] [g=0.86,r=0.88,b=0.76]
\definecolor [color:background:two] [.9(color:title:two)]
\starttext
\startchapter[title=One][mycolor=one] \input tufte \page \input knuth
\stopchapter
\startchapter[title=Two][mycolor=two] \input tufte \page \input knuth
\stopchapter
\stoptext
Of course more solutions are possible. Btw, watch the topboundary
trickery and the fractional color.
