%AM: NOTE: The black and blue colors can be made configurable.
%D First, we change the page layout to have more space on the top and the
%D bottom.
\setuplayout [width=fit,
margin=0cm,
height=fit,
header=3.2cm,
footer=.5cm,
topspace=.6cm,
backspace=1cm,
location=singlesided]
\setuplayout [simpleslides:layout:horizontal][header=3.2cm]
\setuplayout [simpleslides:layout:vertical] [header=0.5cm]
\setuplayout [simpleslides:layout:title] [header=0.5cm]
%D We also specify the position of the slidetitle.
\setuplayer[simpleslides:layer:slidetitle]
[x=10mm,y=12mm]
%D These macros are used for placing figures/pictures:
\define\NormalHeight {\textheight}
\define\NormalWidth {.476\textwidth}
\define\PictureFrameHeight {\textheight}
\define\PictureFrameWidth {.476\textwidth}
%D Next we define a few generic frames, which will be used by other macros to
%D get a consistent look and feel.
\setupframed[simpleslides:framed]
[corner=round,
background=color,backgroundcolor={simpleslides:contrastcolor}]
\defineframed[simpleslides:framed:small]
[frame=off,offset=0pt,strut=no,
width=0.5\textwidth,height=0.5cm,
top=\vss,bottom=\vss]
%D We define our color scheme:
\definecolor [simpleslides:backgroundcolor] [s=.9]
\definecolor [simpleslides:contrastcolor] [r=.2, g=.2, b=.72]
\definecolor [simpleslides:variantcolor] [s=0]
\definecolor [simpleslides:itemize:color] [simpleslides:contrastcolor]
%D We use \METAPOST\ to draw backgrounds. First, we define a few helper macros
%D to place text inside \METAPOST
\definetextext[simpleslides:sometxt:left] {\SimpleSlidesSometxtLeft}
\definetextext[simpleslides:sometxt:right]{\SimpleSlidesSometxtRight}
\unexpanded\def\SimpleSlidesSometxtLeft#1%
{\getvalue{simpleslides:framed:small}[align=left]
{\switchtobodyfont[9pt]\color[simpleslides:backgroundcolor]
{#1\quad\strut}}}
\unexpanded\def\SimpleSlidesSometxtRight#1%
{\getvalue{simpleslides:framed:small}[align=right]
{\switchtobodyfont[9pt]\color[simpleslides:backgroundcolor]
{\strut\quad#1}}}
%D Now we use \METAPOST\ to draw a page ornament, which will then be inherited
%D by different backgrounds.
