%D This is a nice and simple style, written in februari
%D 2001. It uses a square papersize, derived from \type {S4}.
%D Because this style is meant to be used with Zapf
%D Chancery, I dedicate this style to Volker Schaa, a fan of
%D Zapf.

%D We use the whole page.
\setuplayout

width=middle,

%D We will be very tolerant in alignment.

%D Of course use navigation, but we hide the in this case
%D ugly reverse video hyper spot.
\setupinteraction
[state=start,
color=white,
contrastcolor=white,
style=\underbar,
click=no]
%D This style looks best in a dark room, full screen.

%D We use colors and remap a couple of standard colors.
\setupcolors
[state=start]
\definecolor[white] [s=.8]
\definecolor[red] [r=.7]
\definecolor[green] [g=.7]
\definecolor[blue] [b=.7]
\definecolor[yellow][r=.7,g=.7]
\definecolor [PageColor][black]
%D These colors will cyclic be assigned to \type
%D {TextColor}.
\definecolor [TextColor 0][white]
\definecolor [TextColor 1][red]
\definecolor [TextColor 2][green]
\definecolor [TextColor 3][blue]
\definecolor [TextColor 4][yellow]

%D We will collect everything in a layer.
\definelayer
[main]
[state=repeat]
%D We have quite some overlays.
\defineoverlay [page] [\reuseMPgraphic{page}]
\defineoverlay [text] [\useMPgraphic{text}]
\defineoverlay [next] [\overlaybutton{nextpage}]
\defineoverlay [prev] [\overlaybutton{previouspage}]
\defineoverlay [main] [\composedlayer{main}]
%D These end up as paper, page and text backgrounds. We need
%D to locate the foreground, otherwise hyperlinks will not
%D work.
\setupbackgrounds % otherwise in acrobat 5 rounding error
[paper] % and one pixel white line

background=page]
\setupbackgrounds

[background={page,prev,foreground,main}]
\setupbackgrounds
[text]
[background=next,
backgroundoffset=-10pt]
%D This means that clicking on the center brings you to the
%D next page, while clicking on teh page frame brings you one
%D page back.
%D As usual, the graphics are handled by \METAPOST:
\startuseMPgraphic{text}
path p ; p := unitsquare xyscaled (OverlayWidth,OverlayHeight) ;
color c ; c := (.7+uniformdeviate.3)*\MPcolor{TextColor} ;
p := p enlarged -1.25pt ;
filldraw p withcolor c ;
draw p withpen pencircle scaled 2.5pt withcolor .75c ;
\stopuseMPgraphic
\startreusableMPgraphic{page}
path p ; p := unitsquare xyscaled (OverlayWidth,OverlayHeight) ;
color c ; c := \MPcolor{PageColor} ;
filldraw p enlarged 5pt withcolor c ; % bleeding
\stopreusableMPgraphic
%D The text is typeset in a framed text. We cycle trough the
%D colors by means of a counter. This counter also determines
%D the positioning on the main layer. The width is slightly
%D random.
