%D module. It is loaded at runtime.

%D First, we change the page layout to have more space all around
\setuplayout [width=fit,
margin=2cm,
height=fit,
leftmargindistance=.8cm,
rightmargindistance=0cm,
header=18mm,
footer=0cm,
topspace=.8cm,
backspace=1.9cm,
location=singlesided]
\setuplayout [simpleslides:layout:horizontal][header=18mm]
\setuplayout [simpleslides:layout:vertical] [header=0mm]
\setuplayout [simpleslides:layout:title]
\setuplayer[simpleslides:layer:slidetitle]
[width=\paperwidth,
height=\paperheight,x=20mm]
%D Next we a generic frames, which will be used by other macros to
%D get a consistent look and feel.
\defineframed[simpleslides:framed:small]
[frame=off,offset=0pt,
width=1.7cm,align=middle]
\setupcombinations[distance=2.5em]
%D These macros are used for placing figures/pictures:
\define\NormalHeight {\textheight}
\define\NormalWidth {.46\textwidth}
\define\PictureFrameHeight {\textheight}
\define\PictureFrameWidth {.46\textwidth}
%D This module has two color schemes, a blue one and a red one.
\startsetups simpleslides:setups:blue
\definecolor [simpleslides:contrastcolor] [r=0.8,g=0.8,b=0.9]
\definecolor [simpleslides:backgroundcolor] [s=.88]
\definecolor [simpleslides:textcolor] [s=0]
\stopsetups
\startsetups simpleslides:setups:red
\definecolor [simpleslides:contrastcolor] [r=0.4]
\definecolor [simpleslides:backgroundcolor] [s=.35]
\definecolor [simpleslides:textcolor] [s=1]
\stopsetups
%D Now we choose the scheme that the user asked for
\doifsetupselse{simpleslides:setups:\moduleparameter{simpleslides}{color}}
{\setups{simpleslides:setups:\moduleparameter{simpleslides}{color}}}
{\setups{simpleslides:setups:blue}}
\setupcolors[textcolor={simpleslides:textcolor}]
%D The characteristic feature of this module is that the page number is drawn in
%D big letters on the slide. First we define the font used to draw the number.
%D The is a bit verbose since \MKII\ and \MKIV\ have different ways of loading
%D fonts.
\beginOLDTEX
\loadmapfile[qhv-ec.map]
\definefontsynonym [BigNumberFont] [ec-qhvb]
\endOLDTEX
\beginXETEX
\loadmapfile[qhv-ec.map]
\definefontsynonym [BigNumberFont] [ec-qhvb]
\endXETEX
\beginLUATEX
\definefontsynonym [BigNumberFont] [name:texgyreherosbold]
\endLUATEX
\definefont [NumberFont] [BigNumberFont at 30pt]
%D We use \METAPOST\ to draw backgrounds. First, we define a few helper macros
%D to place text inside \METAPOST
\definetextext[simpleslides:sometxt:left] {\TaspresentSometxtLeft}
\definetextext[simpleslides:sometxt:right]{\TaspresentSometxtRight}
\unexpanded\def\TaspresentSometxtLeft#1%
{\getvalue{simpleslides:framed:small}
{\color[simpleslides:contrastcolor]
{\NumberFont #1}}}
\unexpanded\def\TaspresentSometxtRight#1%
{\getvalue{simpleslides:framed:small}
{\color[simpleslides:backgroundcolor]
{\NumberFont #1}}}
%D Now we define a \METAPOST| graphic that draws the number. The exact
%D dimensions have been found by trial and error.

%D We also use \METAPOST\ to draw the horizontal and vertical page backgrounds.

\stopuniqueMPgraphic
%D We define these backgrounds as overlays:
\defineoverlay
[simpleslides:background:horizontal]
[\useMPgraphic{simpleslides:MP:horizontal}]
\defineoverlay
[simpleslides:background:vertical]
[\useMPgraphic{simpleslides:MP:vertical}]
\defineoverlay
[simpleslides:background:title]
[\useMPgraphic{simpleslides:MP:horizontal}]
\defineoverlay
[simpleslides:background:ornament]
[\useMPgraphic{simpleslides:MP:ornament}]
%D The slide title is placed on the top of the text area. The layer takes care
%D of the positioning.
\setupSlideTitle
[\c!after=,
\c!alternative=layer,
\c!width=\textwidth,
\c!height=2.5cm,

%D Squares are used as the first level of itemizations
