%D \module
%D [ file=s-present-split, % s-pre-14,
%D version=1999.08.20,
%D title=\CONTEXT\ Style File,
%D subtitle=Presentation Environment Split,
%D author=Hans Hagen,
%D date=\currentdate,
%D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}]
%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D In the process of making a couple of simple styles for \EUROTEX\ 99, I came to
%D this one. The joke is in the pagenumber. This style can be used for short
%D presentations with much text.
\startmodule[present-split]
\startmode[asintended,atpragma] \setupbodyfont[lucidaot] \stopmode
\setupbodyfont[14.4pt]
%D Since we expect text, we can best be very tolerant.
\setuptolerance
[verytolerant,stretch]
%D As most styles we choose a large screen page size.
\setuppapersize
[S6][S6]
\setuplayout
[width=fit,
rightedge=3cm,
margin=0pt,
rightedgedistance=2cm,
height=middle,
header=0pt,
footer=0pt,
topspace=1cm,
backspace=1cm]
%D We only use two colors, named \type {ColorOne} and \type {ColorTwo}:
\definecolor [ColorOne] [r=.6,g=.4,b=.4]
\definecolor [ColorTwo] [r=.4,g=.6,b=.6]
%D If you've looked at the demo file, you will have noticed that the background
%D consists of four pieces: two filled rectangles and two half numbers. In older
%D versions these are put on the page using four overlays, here we use a much
%D cleaner implementation is the following. If you hate \METAPOST, you can run
%D this style in the specified mode:
\setupbackgrounds
[page]
[background={number}]
\defineoverlay[number][\useMPgraphic{number}]
\startuseMPgraphic{number}
StartPage ;
picture Left, Right ;
numeric Shift ; Shift := -TextWidth - BackSpace - RightEdgeDistance/2 ;
fill Page withcolor "ColorOne" ;
fill Page leftenlarged Shift withcolor "ColorTwo" ;
if RealPageNumber > 1 :
Left := Right := textext("\bf\folio") ysized 3cm ;
clip Right to boundingbox Right shifted ( bbwidth(Right)/2,0) ;
clip Left to boundingbox Left shifted (-bbwidth(Left) /2,0) ;
draw Left shifted (-Shift,2.25cm) withcolor "ColorTwo" ;
draw Right shifted (-Shift,2.25cm) withcolor "ColorOne" ;
fi ;
StopPage ;
\stopuseMPgraphic
%D We use the simple label typesetting present in \METAPOST\ because digits are
%D seldom kerned so real \TEX ing is not needed. As in the previous method, we let
%D the graphics overlap so that we don't get white lines due to rounding problems in
%D viewers.
%D
%D We put a button behind the text (this overlay is calculated each page).
\defineoverlay
[nextpage]
[\overlaybutton{nextpage}]
\setupbackgrounds
[text]
[backgroundoffset=.5cm,
background=nextpage]
%D We still have to turn on interaction mode.
\setupinteraction
[state=start,
display=new,
menu=on]
\setupinteraction
[color=,
contrastcolor=]
%D Next we define structuring commands.
\definehead[Topic] [chapter] \setuphead[Topic] [style=\bfc]
\definehead[Subject][section] \setuphead[Subject][style=\bfa]
\setuphead
[Topic,Subject]
[number=no,
after={\blank[big]}]
%D Because we will provide a menu, we don't offer lists.
\let\Topics \gobbleoneargument
\let\Subjects\relax
%D The table of contents goes to the right edge.
\startinteractionmenu[right]
\setupinteraction
[color=black,
contrastcolor=Two]
\placelist
[Topic]
[alternative=e,
frame=off,
criterium=all]
\vfill
\stopinteractionmenu
\setuplist
[Topic]
[width=\rightedgewidth,
maxwidth=\rightedgewidth,
style=\bfa]
%D We safe some space:
\setupwhitespace
[medium]
\setupblank
[medium]
%D In the titlepage, we still use the \TEX\ overlays, so that we don't have to
%D define a second graphic.
