%D This file provides the \quotation{superellipse} style for the presentation
%D module. The design is inspired by Hans's "funny" presentation module
%D (s-pre-03). It is loaded at runtime.

%D The taspresentation module provides a skeleton into which different styles
%D can be hooked. It uses a number of variables and macros which have to be set
%D beforehand. Some parts are optional. We begin with the necessary definitions:
%D We define our colors:
\definecolor[outer][s=0]
\definecolor[inner][s=.8]
\definecolor[ellipse][r=.5,g=0,b=0]
\definecolor[contrast][r=.9,g=0,b=0]
\definecolor[Item] [r=.5]
%D We start colors:
\setupcolors[state=start]
%D These macros are used for placing figures/pictures:
\define\NormalHeight{\textheight}
\define\NormalWidth{.5\textwidth}
\define\PictureFrameHeight{\textheight}
\define\PictureFrameWidth{.5\textwidth}
%D The page layout:
\setuplayout [width=fit,
height=fit,
margin=0cm,
header=1.2cm,
footer=0cm,
topspace=1.8cm,
backspace=1.5cm,
location=singlesided]
%D The macro for typesetting the Slidetitle; this is adapted from a sample
%D document that Brooks Moses published on the wiki:
\definelayer[slidetitle]
[width=\paperwidth,
height=\paperheight,
y=10mm,
x=15mm]
\define[1]\Slidetitle{\page\setlayer[slidetitle]%
{\framed[frame=off,width=\textwidth,height=2.5cm,offset=0pt,top=\vss,bottom=\vss]{\switchtobodyfont[\Titlesize]\color[ellipse]{#1}}}}
%D The macro \tex{Maketitle} produces a default title page with the author, the
%D title of the presentation, and the date. Using it is not mandatory.
\define\Maketitle{%
\titback
\null
\vfill
\midaligned{\switchtobodyfont[\Titlesize]\color[ellipse]{\getvariable{taspresent}{title}}}
\blank[2*line]
\midaligned{\color[ellipse]{\getvariable{taspresent}{author}}}
\blank[3*line]
\midaligned{\color[ellipse]{\currentdate}}
\vfill
\null}
%D The following parts are optional; if you don't use backgrounds and are
%D content with CONTEXT's default itemization, you don't have to set these
%D macros.
%D We let Metapost calculate the background:
\startuseMPgraphic{left}
StartPage ;
fill Page withcolor \MPcolor{outer} ;
path p ; pair pa ; pair pb ;
p := Page enlarged (-15pt,-15pt) superellipsed .9 ;
fill p withcolor \MPcolor{inner} ;
pickup pencircle scaled 20pt ;
draw p withcolor \MPcolor{ellipse} ;
if PageNumber>1:
pa := point (3 + (6*PageNumber) / NOfPages) of p ;
pb := point (3 + (6*(PageNumber-1)) / NOfPages) of p ;
draw (p cutafter pa) cutbefore pb withcolor \MPcolor{contrast} ;
fi ;
% draw point 1 of p withcolor \MPcolor{contrast} ;
% draw point 8 of p withcolor blue ;
% draw point 4 of p withcolor green ;
% draw point 3 of p withcolor yellow ;
% draw point 2 of p withcolor cyan ;
% draw point 7 of p withcolor white ;
StopPage ;
\stopuseMPgraphic
%D We define these backgrounds as overlays:
\defineoverlay
[lecbackground]
[\useMPgraphic{left}]
%D These are shortcuts to switch backgrounds:
\define\lecback{\setuplayout[header=1.5cm]\setupbackgrounds[page][background={lecbackground,slidetitle}]}
\define\titback{\setuplayout[header=0cm]\setupbackgrounds[page][background=lecbackground]}
\define\picback{\setuplayout[header=0cm]\setupbackgrounds[page][background={lecbackground,slidetitle}]}
\define\noback{\setupbackgrounds[page][background=nobackground]}
%D We use combinations for placing vertical pictures and text side by side, and
%D we want a distance of 1.1 cm between both.
\setupcombinations[distance=0cm]
%D The symbol for the first level of itemizations.
\definesymbol[1][\useMPgraphic{ItSquare}]
\setupitemize[1][color=ellipse]
