%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 start colors; textcolor is white:
\setupcolors[state=start]
%D These macros are used for placing figures/pictures:
\define\NormalHeight{\textheight}
\define\NormalWidth{.476\textwidth}
\define\PictureFrameHeight{\textheight}
\define\PictureFrameWidth{.476\textwidth}
%D The page layout:
\setuplayout [width=fit,
leftmargin=1.5cm,
rightmargin=0cm,
leftmargindistance=.9cm,
rightmargindistance=0pt,
height=fit,
header=2.5cm,
footer=0cm,
topspace=.4cm,
backspace=2.9cm,
cutspace=2.8cm,
bottomspace=0cm,
bottom=0pt,
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,
x=29mm]
\define[1]\Slidetitle{\page\setlayer[slidetitle]%
{\framed[frame=off,height=2.5cm,offset=0pt,top=\vss,bottom=\vss]{\switchtobodyfont[\Titlesize]\color[a]{#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[b]{\getvariable{taspresent}{title}}}
\blank[2*line]
\midaligned{\color[b]{\getvariable{taspresent}{author}}}
\blank[3*line]
\midaligned{\color[b]{\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 define our colors:
\definecolor [Item] [s=.9]
\definecolor [a] [s=.9]
\definecolor [c] [r=.15,g=.15,b=.525]
\definecolor [b] [r=.2,g=.2,b=.7]
\definecolor [d] [s=.4]
%D We let Metapost calculate the background:
\startuseMPgraphic{stripe}
StartPage ;
numeric a, dur, now, before, proa, prob ;
pair k[], F[] ;
a = 2.5cm ;
dur = 1.5cm ;
k[1] = ulcorner Page shifted (a,0) ;
k[2] = llcorner Page shifted (a,0) ;
k[3] = ulcorner Page shifted (0,-a) ;
k[4] = urcorner Page shifted (0,-a) ;
k[5] = ulcorner Page shifted (a,-a) ;
path p[] ;
p[1] = ulcorner Page -- k[1] -- k[2] -- llcorner Page -- cycle ;
p[2] = ulcorner Page -- urcorner Page -- k[4] -- k[3] -- cycle ;
p[3] = ulcorner Page -- k[1] -- k[5] -- k[3] -- cycle ;
fill Page withcolor \MPcolor{a} ;
fill p[1] withcolor \MPcolor{b} ;
fill p[2] withcolor \MPcolor{b} ;
fill p[3] withcolor \MPcolor{c} ;
pickup pencircle scaled 5pt ;
if \realfolio > 1:
before = PageNumber - 1 ;
now = NOfPages - 1 ;
prob = before/now ;
p[4] = unitcircle scaled dur rotated 90 shifted (dur + ((a-dur)/2),(a-dur)/2) ;
fill p[4] withcolor \MPcolor{a} ;
F[0] = center p[4] ;
F[1] = point 1 along p[4] ;
F[2] = point -prob along p[4] ;
F[3] = point -prob/2 along p[4] ;
p[5] = F[0] -- F[1] .. F[3] .. F[2] -- cycle ;
fill p[5] withcolor \MPcolor{d} ;
fi ;
StopPage ;
\stopuseMPgraphic
%D We define these backgrounds as overlays:
\defineoverlay
[lecbackground]
[\useMPgraphic{stripe}]
%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=1.1cm]
%D These are shortcuts to switch backgrounds:
\define\lecback{\setupbackgrounds[page][background={lecbackground,slidetitle}]}
\define\titback{\setupbackgrounds[page][background=lecbackground]}
\define\picback{\setupbackgrounds[page][background={lecbackground,slidetitle}]}
\define\noback{\setupbackgrounds[page][background=nobackground]}
\setupbackgrounds[page][background=lecbackground]
%D The symbol for the first level of itemizations.
\definesymbol[1][\useMPgraphic{ItTriangle}]
\setupitemize[1][inmargin][color=a]
