%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:
\setupcolors[state=start]
%D These macros are used for placing figures/pictures:
\define\NormalHeight{.97\textheight}
\define\NormalWidth{.476\textwidth}
\define\PictureFrameHeight{.97\textheight}
\define\PictureFrameWidth{.476\textwidth}
%D The page layout:
\setuplayout [width=fit,
margin=0cm,
height=14.7cm,
header=1.75cm,
footer=1.2cm,
topspace=1cm,
backspace=1cm,
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=10mm]
\define[1]\Slidetitle{\page\setlayer[slidetitle]%
{\framed[frame=off,width=\textwidth,height=2.2cm,offset=0pt,top=\vss,bottom=\vss]{\switchtobodyfont[\Titlesize]\color[c]{#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
\framed[frame=off,width=\textwidth,height=.75\textheight,top=\vss,bottom=\vss,align=middle]{\switchtobodyfont[\Titlesize]\color[c]{\bf \getvariable{taspresent}{title}}\switchtobodyfont[\Normalsize]\blank[line]\getvariable{taspresent}{author}\blank[2*line]\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 [a] [s=.95]
\definecolor [b] [r=.58,g=.58,b=.82]
\definecolor [c] [r=.2,g=.2,b=.73]
\definecolor [Item] [r=.2,g=.2,b=.73]
%D We let Metapost calculate the background:
\startuniqueMPgraphic{vertical}
StartPage ;
pair zd[] ;
path pb[] ;
fill Page withcolor \MPcolor{a} ;
z.d1 = ulcorner Page shifted (0,-5pt) ;
z.d2 = urcorner Page shifted (0,-5pt) ;
pb[1] = ulcorner Page -- z.d1 -- z.d2 -- urcorner Page -- cycle ;
z.d3 = llcorner Page shifted (0,5pt) ;
z.d4 = lrcorner Page shifted (0,5pt) ;
pb[3] = llcorner Page -- z.d3 -- z.d4 -- lrcorner Page -- cycle ;
pb[4] = pb[3] shifted (0,.75cm) ;
fill pb[1] withcolor \MPcolor{b} ;
fill pb[3] withcolor \MPcolor{b} ;
fill pb[4] withcolor \MPcolor{b} ;
StopPage ;
\stopuniqueMPgraphic
\startuniqueMPgraphic{horizontal}
StartPage ;
pair zd[] ;
path pb[] ;
z.d1 = ulcorner Page shifted (0,-5pt) ;
z.d2 = urcorner Page shifted (0,-5pt) ;
pb[1] = ulcorner Page -- z.d1 -- z.d2 -- urcorner Page -- cycle ;
pb[2] = pb[1] shifted (0,-2cm) ;
fill pb[2] withcolor \MPcolor{b} ;
StopPage ;
\stopuniqueMPgraphic
%D We define these backgrounds as overlays:
\defineoverlay
[lecbackground]
[\useMPgraphic{horizontal}]
\defineoverlay
[picbackground]
[\useMPgraphic{vertical}]
%D We define the footer
\setupfooter[color=c,style={\switchtobodyfont[10pt]},strut=yes]
\setupfootertexts[{\framed[frame=off,height=.45cm,width=\textwidth]{\getvariable{taspresent}{title}\hfill \pagenumber \ of \lastpage}}]
%D These are shortcuts to switch backgrounds:
\define\lecback{\setuplayout[header=1.75cm]\setupfooter[state=start]\setupbackgrounds[page][background={picbackground,lecbackground,slidetitle}]}
\define\titback{\setuplayout[header=1.75cm]\setupfooter[state=stop]\setupbackgrounds[page][background={picbackground,lecbackground}]}
\define\picback{\setuplayout[header=0cm]\setupfooter[state=start]\setupbackgrounds[page][background={picbackground}]}
\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=1.1cm]
%D The symbol for the first level of itemizations.
\definesymbol[1][\useMPgraphic{ItSquare}]
\setupitemize[1][color=c]
