%D This file provides the \quotation{Sunrise} style for the presentation
%D module. It is loaded at runtime. The look of this style was inspired by the
%D \quotation{husky} theme of the \LaTeX\ {\tt powerdot} package, created by
%D Jack Stalnaker.

%D These macros are used for placing figures/pictures:

\define\NormalHeight        {\textheight}
\define\NormalWidth         {.476\textwidth}
\define\PictureFrameHeight  {\textheight}
\define\PictureFrameWidth   {.476\textwidth}

%D We define our color scheme:

\definecolor [simpleslides:variantcolor]      [s=.97]
\definecolor [simpleslides:backgroundcolor]   [s=.88]
\definecolor [simpleslides:contrastcolor]     [r=.75]
\definecolor [simpleslides:itemize:color]     [simpleslides:contrastcolor]

%D We let \METAPOST\ calculate the background:

%D Both horizontal and vertical group share this part of the background.

%D We define these backgrounds as overlays:

\defineoverlay 
  [simpleslides:background:title] 
  [\useMPgraphic{simpleslides:MP:horizontal}] 

\defineoverlay 
  [simpleslides:background:horizontal] 
  [\useMPgraphic{simpleslides:MP:horizontal}] 

\defineoverlay 
  [simpleslides:background:vertical] 
  [\useMPgraphic{simpleslides:MP:vertical}] 

%D We define the footer

\setupfooter[\c!color=simpleslides:variantcolor,
             \c!style={\switchtobodyfont[10pt]},
             \c!strut=\v!yes]

\setupfootertexts[{\framed[\c!frame=\v!off,
                           \c!height=1cm,
                           \c!width=\textwidth]

                            \hfill \pagenumber\ of \lastpage}}]

%D We want the title to placed in a framed box. We redefine all the keys of
%D \type{\setupTitle}, so that the module is easier to maintain.
