-\section Introduction
-
-This module provides an easy|-|to|-|use interface
-for creating simple slides/presentations in \CONTEXT.
-The salient features of this module are:
-\startitemize
- \item The module is meant for presentations which will be shown on a
- digital projector. They have no interactive elements (such as buttons or
- hyperlinks) and no navigational tools (such as table of contents).
- \item The module comes with several predefined styles; these styles are sober
- in appearance and meant for academic presentations. It also provides some
- macros to help in presenting slides with both pictures and text.
- \item Most styles allow for some degree of user|-|reconfigurability. Designing
- a new style is also easy.
-\stopitemize
-
-This module provides a simple structure that will be suitable for beginning or
-intermediate users of \CONTEXT, or someone who does not want to spend too much
-time playing around with different configuration options for \CONTEXT. As such
-it focusses on different users than Hans's presentation modules that provide
-more fancier features. This module also offers much less features than the
-\LATEX\ \filename{beamer} package. Its main strength is its ease of use; you
-should be able to write your first presentation after spending five minutes with
-this manual.
-
-\section A bit of history
-
-The idea of a module suitable for simple presentations took shape when Thomas
-started using \CONTEXT\ for preparing his course presentations. \CONTEXT\ comes
-with a bunch of modules for presentations (the files \filename{s-pre-??.tex} in
-\filename{$TEXMF/tex/context/base}) which are written by Hans Hagen. Hans
-usually creates a new presentation style whenever he gives a talk about
-\CONTEXT. As such, his presentation styles highlight the fancy and bleeding edge
-features of \CONTEXT, and are not the most suitable starting point for academic
-presentations.
-
-\CONTEXT\ does make creating your own presentation style relatively easy. So
-Thomas wrote some presentation related macros (see the Prac\TEX\ article
-{\tt\from[practex]}). With time, he extended these macros into a collection of
-styles providing different visual effects, and later collected all of them in
-the \filename{taspresent} module. He gave a talk about the
-\filename{taspresent} module in in the second \CONTEXT\ user meeting at Bohinj,
-and in the ensuing discussions, Aditya and Thomas decided to modularize and
-\quotation{\CONTEXT{ize}} some of the internals of the module, giving rise to
-the current module. Most of the code in the current release has been
-contributed by Aditya.
-
-\section{Installation}
-
-The module is installed in the usual way: simply unzip the archive
-\filename{t-simpleslides-<date>.zip} into one of your \filename{$TEXMF} trees,
-and from a terminal run \command{mktexlsr} (for \MKII) and \command{luatools
---generate} (for \MKIV). To verify that everything was installed correctly, from
-a terminal run \command{kpsewhich t-simpleslides.tex} (for \MKII) and
-\command{luatools t-simpleslides.tex} (for \MKIV); these commands should return
-the complete path of the files that you just installed.
-
-\subsubject A note about \TEX|-|engines
-
-We have extensively tested this module with \PDFTEX\ and \LUATEX\ (that is,
-with \MKII\ and \MKIV). In spite of our best efforts, we have not been able to
-get this module to work reliably with \XETEX. If you are a \XETEX\ guru, and
-know how to fix some of the errors with \XETEX, we will appreciate the help.
-
-\section Quick start
-
-First you must tell \CONTEXT\ that you want to use this module. To do this
-simply write:
-
-\startEXAMPLE
-\startTEX
-\usemodule[simpleslides]
-\stopTEX
-\stopEXAMPLE
-
-This sets the paper size and font sizes to values that are suitable for
-presentations. Everything else is left like a default \CONTEXT\ document. The
-module provides different styles that change the visual appearance of the
-presentation. The following styles are provided:
-\startitemize[columns, three]
- \item \options{BigNumber}
- \item \options{BottomSquares}
- \item \options{Boxed}
- \item \options{Ellipse}
- \item \options{Embossed}
- \item \options{Framed}
- \item \options{FramedTitle}
- \item \options{HorizontalStripes}
- \item \options{NarrowStripes}
- \item \options{RainbowStripe}
- \item \options{Rounded}
- \item \options{Shaded}
- \item \options{SideSquares}
- \item \options{Split}
- \item \options{Sunrise}
- \item \options{Swoosh}
- \item \options{ThickStripes}
-\stopitemize
-
-To use a style, say \options{BigNumber}, pass the \options{style=BigNumber}
-option to the \filename{simpleslides} module as follows.
-
-\startEXAMPLE
-\startTEX
-\usemodule[simpleslides]
- [style=BigNumber]
-\stopTEX
-\stopEXAMPLE
-
-Some of the styles have a few variants that can be chosen using
-\options{color} and \options{alternative} keys. These are explained in \in
-Section[sec:styles].
-
-By default, the Latin Modern Sans font is used. The module makes it easy to
-use other fonts that come with a typical \TEX\ distribution.
-The following fonts are provided:
-\startitemize[columns, three]
- \item \options{LatinModern}
- \item \options{LatinModernSans}
- \item \options{Bookman}
- \item \options{Chancery}
- \item \options{Gothic}
- \item \options{Helvetica}
- \item \options{Palatino}
- \item \options{Schoolbook}
- \item \options{Times}
-\stopitemize
-
-To choose a font, say \options{Helvetica}, pass \options{font=Helvetica} option
-to the \filename{simpleslides} module as follows.
-\startEXAMPLE
-\startTEX
-\usemodule[simpleslides]
- [style=BigNumber,
- font=Helvetica]
-\stopTEX
-\stopEXAMPLE
-
-By default, the chosen font is used at 17pt size. The font size can be changed
-using the \options{size} key.
-
-More details about the fonts, including information on how to use your own fonts
-is given in \in Section[sec:fonts].
-
-The complete setup for using this module is
-\setup{simpleslides}
-
-\subsubject Structure of a presentation
-
-The \filename{simpleslides} module has a very simple model of a presentation. A
-presentation consists of a title followed by a series of slides; the module
-provides macros to help create a presentation title page and slides.
-
-\subsubject Presentation title page
-
-A presentation title page displays the title of the presentation, the names of
-the authors, and the date.
-%% TODO: Also add institution and detail.
-These can be specified using \typeTEX{\setupTitle} as follows:
-\startEXAMPLE
-\startTEX
-\setupTitle
- [ title={Title of the presentation},
- author={Name of authors},
- date={Date of presentation},
- ]
-\stopTEX
-\stopEXAMPLE
-
-The macro \typeTEX{\placeTitle} places the title page in the presentation. It is
-possible to change the look of \typeTEX{\placeTitle} using some additional
-arguments to \typeTEX{\setupTitle}. These are explained in \in
-Section[sec:setuptitle].
-
-\subsubject Presentation slide
-
-The \filename{simpleslides} module provides a \typeTEX{\SlideTitle} macro, which
-starts a new slide (basically a new page), and typesets its argument as the
-title of the slide. It also takes care of increasing the page counters and
-progress bars, and setting up the background. The content of the slides follows
-after this command.
-
-A slide is a normal \CONTEXT\ page, so you can use any command or environment
-that you want. Each presentation style sets up a style for itemizations, and
-provides useful macros for placing pictures. These macros will be explained
-later.
-
-\adaptlayout[lines=+2]

-\subsubject A minimal presentation
-
-A minimal presentation is shown below. The result is shown in \in
-Figure[fig:example].

-\section Placing pictures
-
-If you want to place pictures in your slides, you can always use \CONTEXT's
-\typeTEX{\externalfigure} macro. This module also provides a macro,
-\typeTEX{\IncludePicture}, for preconfigured picture layouts. Two layouts are
-provided:
-\startitemize
- \item \options{horizontal}: the picture is placed under the title of the slide,
- so that it fits in the available space.
- \item \options{vertical}: the slide is divided into two columns; the picture is
- placed on the left column and text is placed on the right column.
-\stopitemize
-These layouts are shown in \in Figure[fig:pictures].
-

- {\externalfigure[styles/BigNumber-blue]
- [page=10,width=0.55\textwidth]}{A vertical picture}
-\stopcombination
-
-A horizontal picture is placed as follows:
-\startEXAMPLE
-\startTEX
-\IncludePicture
- [horizontal]
- [filename] % Name of the file that contains the picture
- {Title of the slide}
-\stopTEX
-\stopEXAMPLE
-
-while a vertical picture is placed as follows:
-\startEXAMPLE
-\startTEX
-\IncludePicture
- [vertical]
- [filename] % Name of the file that contains the picture
- {Text that is placed on the right of the picture}
-\stopTEX
-\stopEXAMPLE
-
-It is possible to change the height and width of the pictures, or
-highlight them with circles and arrows. These details can be found in \in
-Section[sec:pictures]
-
-\page
-
-\section[sec:styles] Changing presentation styles
-
-The \options{style} key to \typeTEX{\setupmodule[simpleslides]} determines the
-look of the presentation. Some of the styles come with variants, that can be
-chosen using \options{color} and \options{alternative} keys. The available
-styles are shown below along with the details of their variants.
-
-\subsubject{BigNumber: with \options{color=blue} (also accepts \options{color=red})}
-
-This is a style with subdued and quiet colors; its characteristic feature is the
-page number on the lower right border of the text area. This detail was inspired
-by {\em split} style (\filename{s-pre-14}) by Hans.
-
-\ShowStyle {BigNumber-blue}
-\page
-
-\subsubject{BottomSquares}
-
-This minimalistic style is inspired by a presentation Taco gave at EuroTeX
-2006.
-
-\ShowStyle {BottomSquares}
-\page
-
-\subsubject{Boxed}
-
-This style is inspired by the screen version of the Metafun manual. Watch
-the small gray circles at the bottom!
-
-\ShowStyle {Boxed}
-\page
-
-\subsubject{Ellipse}
-
-This style is inspired by {\em funny} style (\filename{s-pre-03}) by Hans.
-The light red stripe marks the progress.
-
-\ShowStyle {Ellipse}
-\page
-
-\subsubject{Embossed}
-
-Spread the word, don't be shy! Show your pride in using \CONTEXT. The color
-theme will probably look familiar; I copied it from the \filename{enattab}
-manual.
-
-\ShowStyle {Embossed}
-
-If you are shy, or narcissistic, you can change the emblem by
-\startEXAMPLE
-\startTEX
-\setuplabeltext [simpleslidesemblem={I made this presentation}]
-\stopTEX
-\stopEXAMPLE
-
-\page
-
-\subsubject{Framed: with \options{alternative=square}}
-
-This style was inspired by {\em green} style (\filename{s-pre-02}) by Hans. It
-has a thick blue frame around the entire slide area and a thinner frame around
-the text area. The style has two options for alternative:
-\options{alternative=stripe} will display a shaded blue area which will grow with
-each slide; \options{alternative=square} displays a row of blue squares at the bottom
-which also measure the presentation's progress.
-
-\ShowStyle {Framed-square}
-\page
-
-\subsubject{Framed: with \options{alternative=stripe}}
-\ShowStyle {Framed-stripe}
-\page
-
-\subsubject{FramedTitle}

-\section[sec:fonts] Changing presentation fonts
-
-The \options{font} and the \options{size} keys to
-\typeTEX{\setupmodule[simpleslides]} determine the font and font size for the
-main text of the presentation. The default font is Latin Modern Sans at 17pt.
-
-\startitemize
-\item The \options{font} key can take the following values.
-
-\starttabulate[|l|p|]
-\NC \options{LatinModern} \NC typesets in Latin Modern Serif \NC \NR
-\NC \options{LatinModernSans} \NC typesets in Latin Modern Sans \NC \NR
-\NC \options{Bookman} \NC typesets in \TEX Gyre Bonum (a Bookman
- clone) \NC \NR
-\NC \options{Chancery} \NC typesets in \TEX Gyre Chorus
- \footnote{Please be aware that Chorus is a calligraphic font. It has no
- italic or bold.} (a Zapf Chancery clone) \NC \NR
-\NC \options{Gothic} \NC typesets in \TEX Gyre Adventor (a Gothic
- clone) \NC \NR
-\NC \options{Helvetica} \NC typesets in \TEX Gyre Heros (a Helvetica
- clone) \NC \NR
-\NC \options{Palatino} \NC typesets in \TEX Gyre Pagella (a Palatino

- clone) \NC \NR
-\NC \options{Times} \NC typesets in \TEX Gyre Termes (a Times clone)
-\NC \NR
-\stoptabulate
-
-\item The \options{size} key can be any valid \TEX\ dimension.
-
-\stopitemize
-
-\subsubject Choosing your own font
-
-If you want to set up your own font, pick any value for the \options{font} key
-(or leave it empty). Use the \options{size} key to choose the font size. Then
-{\em after} loading the module, choose any font using the normal \CONTEXT\
-commands. Make sure to set the bodyfont at size \typeTEX{\NormalSize}. So, if
-you have your own typescript for a font, your setup will look like this:
-
-\startEXAMPLE
-\startTEX
-\usemodule[simpleslides][...]
-....
-\usetypescriptfile[type-myfont] % The typescript for your font
-\usetypescript[Mytypescript] % As set in your typescript file
-\setupbodyfont[Myfont,\NormalSize] % Note the \NormalSize here
-\stopTEX
-\stopEXAMPLE
-
-Internally, the font size is stored in the macro \typeTEX{\NormalSize}. The main
-text is set at size \typeTEX{\NormalSize}; the main title is set at
-\typeTEX{\TitleSize} while the author and date on the title page, and the slide
-title are set at \typeTEX{\SlideTitleSize}.
-
-\typeTEX{\NormalSize}, \typeTEX{\TitleSize}, and \typeTEX{\SlideTitleSize} are
-defined in terms of the dimensions \typeTEX{\simpleslidesNormalSize},
-\typeTEX{\simpleslidesTitleSize}, and \typeTEX{\simpleslidesSlideTitleSize}.
-\typeTEX{\simpleslidesNormalSize} is equal to the \options{size} option. The
-module uses some heuristics to select a reasonable value of
-\typeTEX{\simpleslidesTitleSize} and \typeTEX{\simpleslidesSlideTitleSize}. If
-you do not like the size of the title page and slide titles, you can change
-their value to whatever you like.
-
-
-\section[sec:setuptitle] Changing the title page
-
-It is possible to change the look of \typeTEX{\placeTitle} using
-\typeTEX{\setupTitle}. This feature is intended for authors creating a new
-style, but may also be useful for someone who likes to tweak the presentation
-style. You should normally only set the \options{title}, \options{authors}, and
-\options{date} keys. If \options{date} is not set, then the module will default
-to \typeTEX{\currentdate}.
-
-\setup{setupTitle}
-
-\section Changing the slide titles
-
-It is possible to change the look of \typeTEX{\SlideTitle} using
-\typeTEX{\setupSlideTitle}. Like \typeTEX{\setupTitle}, this feature is intended
-for authors creating a new style. You can use this command to make a minor
-change in an existing style, if you want.
-
-\setup{setupSlideTitle}
-
-\section[sec:pictures] Special macro for including pictures
-
-As explained earlier, the \typeTEX{\IncludePicture} macro facilitates the
-placement of pictures. It takes four arguments (one of which is optional, and as
-such wasn't mentioned in the previous description).
-
-\setup{IncludePicture}
-
-As explained earlier, the first argument determines whether the picture will be
-placed in horizontal or vertical layout; for examples, see \in
-Figure[fig:pictures]. The second argument is the filename of the picture that
-you want to include. The third argument is an optional argument useful for
-highlighting the picture. The fourth argument (in braces) is the text
-accompanying the picture. For horizontal pictures, this text is placed as a
-\typeTEX{\SlideTitle}; for vertical pictures this text is placed opposite to the
-picture, centered horizontally and vertically.
-
-The third argument is the most complex. It specifies picture dimensions and
-highlights. If you want all pictures to share a common value (like
-\options{color} or \options{shadow}), specify them using
-\typeTEX{\setupPicture}.
-
-\setup{setupPicture}
-
-\null\blank
-Below is a brief explanation of what the different parameters do:
-
-\startitemize[packed]
- \item \options{width} and \options{height} \par
- Unsurprisingly, these set the width and height of the picture. Normally, the
- module will automatically scale your pictures to fill the available space, so
- you only need to set one of these values if you want to override this
- mechanism.
-
- \item \options{highlight} \par
- This key determines the highlighting of the picture. If you set,
- \options{highlight=yes}, then you can use one of the three available
- highlights: \options{circle}, \options{arrow}, and \options{focus}. These
- highlights are shown in \in Figure[fig:highlight]. The specific highlight is
- chosen using the \options{alternative} key. The location of the highlight is
- specified using the \options{x} and \options{y} keys. The scaling and
- rotation of the highlights is set using \options{xscale}, \options{yscale},
- \options{length} and \options{direction}.
-
- \item \options{alternative} \par
- When \options{highlight=yes}, three different highlights are
- available: \options{circle}, \options{arrow}, and \options{focus}.
-

-
-\subsubject Units for dimensions
-
-All dimensions are specified relative to the width and height of the image, so
-you do not have to change the location of your highlights if you change the
-presentation style. The dimensions \options{x} and \options{y} should be a
-number between 0 and 10. The \options{x} is scaled by 1/10 times the width of
-the image; the \options{y} value is scaled by 1/10 times the height of the
-image. The easiest way to understand this is to look at a scaled grid
-superimposed on the picture, as in \in Figure[fig:grid]. The grid is configured
-as follows:
-
-\startitemize[packed]
- \item \options{grid} and \options{subgrid} \par
- These options determine whether or not to show the grid and sub-grid. The
- \options{grid} divides the height and width of the picture into 10 sections;
- this is helpful for determining the exact position where you want to place
- circles and arrows. The \options{subgrid} divides the grid into a finer
- grid. Each cell is divided into \options{steps} times \options{steps} cells.
-
- \item \options{gridcolor} \par
- This option determines the color in which the grid is drawn. It can be any
- \CONTEXT\ color identifier. The default value is green.
-
- \item \options{steps} \par
- The number of subdivisions for the \options{subgrid}. The default value is
- 5.

-\subsubject Highlighting by a circle
-
-Now lets see how different highlight alternatives are specified. Suppose we want
-to place the picture of a cow and highlight its head. To help determine the
-center of the circle, we can first superimpose a fine grid on the picture, and
-read the value for the center. From \in Figure[fig:grid], \options{x=1.4} and
-\options{y=8.2} seems like a good value. Next we need to decide on the radius of
-the circle. The radius can either be specified in terms of the \quotation{x
-units} (1/10th of the picture width) or \quotation{y units} (1/10th of the
-picture height). Lets try a radius of 1.5 \quotation{x units}. This can be
-specified as \options{xscale=1.5}. If we wanted something in terms of
-\quotation{y units}, we could have used \options{yscale}. If both
-\options{xscale} and \options{yscale} are specified, we will get an ellipse.
-Thus, to draw the circle highlight shown in \in Figure[fig:highlight], we wrote
-
-\startEXAMPLE
-\startTEX
-\IncludePicture
- [horizontal]
- [cow] % Name of the image
- [highlight=yes,
- alternative=circle,
- x=1.4,
- y=8.2,
- xscale=1.5,
- shadow=bottomleft]
- {The head of a dutch cow}
-\stopTEX
-\stopEXAMPLE
-
-If \options{direction} key is specified, the circle (or the ellipse) will be
-rotated by that amount (in degrees) in the counter clockwise direction. The
-color in which the circle is drawn is specified using \options{color} key. The
-thickness of the line is determined by \options{rulethickness} key. By default,
-\options{color=orange} and \options{rulethickness} is 1/100th of the picture
-width.
-
-In summary, the different keys related to \options{alternative=circle} are:
-\startitemize[packed]
- \item \options{highlight=yes} and \options{alternative=circle} \par
- These are needed to specify a circle highlight.
- \item \options{x} and \options{y} \par
- The center of the circle in terms of scaled units. Their values should be
- between 0 and 10.
- \item \options{xscale} and \options{yscale} \par
- The radius of the circle if only one options is specified. The major and
- minor radii of the ellipse if both options are specified.
- \item \options{direction} \par
- The amount by which the circle is rotated. This only makes sense if we are
- actually drawing an ellipse.
- \item \options{rulethickness} \par
- The line width of the circle.
- \item \options{color} \par
- The color of the circle.
-\stopitemize
-
-\subsubject Highlighting by an arrow
-
-Suppose we want to include a picture of a cow and point out its mouth using an
-arrow. An arrow is specified by three things, the location of its tip, given by
-\options{x} and \options{y} keys; the length of the arrow, given by
-\options{length} key; and the direction of the tail, given by
-\options{direction} key. Thus, to draw the arrow highlight shown in \in
-Figure[fig:highlight], we wrote
-\startEXAMPLE
-\startTEX
-\IncludePicture
- [horizontal]
- [cow] % Name of the image
- [highlight=yes,
- alternative=arrow,
- x=0.4,
- y=6.8,
- direction=-90,
- length=3cm,
- shadow=bottomleft]
- {The mouth of a dutch cow}
-\stopTEX
-\stopEXAMPLE
-
-The different keys related to \options{alternative=arrow} are:
-\startitemize[packed]
- \item \options{highlight=yes} and \options{alternative=arrow} \par
- These are needed to specify a arrow highlight.
- \item \options{x} and \options{y} \par
- The tip of the arrow in terms of scaled units. Their values should be
- between 0 and 10.
- \item \options{length} \par
- The length of the arrow. This is a dimension.
- \item \options{direction} \par
- The amount by which the arrow is rotated.
- \item \options{rulethickness} \par
- The line width of the arrow. (Actually the line width of the arrow is twice
- the given value. This is so that both arrows and circles look good with the
- same value of rulethickness.)
- \item \options{color} \par
- The color of the arrow.
-\stopitemize
-
-\subsubject Highlighting by focus
-
-Suppose we want place the picture of a cow, focus its head, and dull out rest of
-the picture. The area to be focused is a circle (or an ellipse) and it can be
-specified using \options{x} and \options{y} to indicate the center,
-\options{xscale} and \options{yscale} to indicate the radius, and
-\options{direction} to indicate the rotation. The keys \options{rulethickness}
-and \options{color} do not have any effect. The area other than the focussed
-area is washed out with a transparent color. The degree to which it is washed
-out is determined by \options{opacity} (default value 0.5), and the color of the
-unfocussed area is determined by \options{shadowcolor} (default value black).
-Thus, to draw the focus highlight shown in \in Figure[fig:highlight], we wrote
-
-\startEXAMPLE
-\startTEX
-\IncludePicture
- [horizontal]
- [cow] % Name of the image
- [highlight=yes,
- alternative=focus,
- x=1.4,
- y=8.2,
- xscale=1.5]
- {The head of a dutch cow}
-\stopTEX
-\stopEXAMPLE
-
-The different keys related to \options{alternative=focus} are:
-\startitemize[packed]
- \item \options{highlight=yes} and \options{alternative=focus} \par
- These are needed to specify a focus highlight.
- \item \options{x} and \options{y} \par
- The center of the circle in terms of scaled units. Their values should be
- between 0 and 10.
- \item \options{xscale} and \options{yscale} \par
- The radius of the circle if only one options is specified. The major and
- minor radii of the ellipse if both options are specified.
- \item \options{direction} \par
- The amount by which the circle is rotated. This only makes sense if we are
- actually drawing an ellipse.
- \item \options{opacity} \par
- The opacity of the unfocussed area. \options{opacity=0} is transparent,
- while \options{opacity=1} is completely opaque.
- \item \options{shadowcolor} \par
- The color of the unfocused area.
-\stopitemize
-
-\subsubject Adding shadows
-
-When a circle or arrow highlight is used, adding a shadow to the highlight makes
-them stand out more. The key related to shadows is:
-\startitemize[packed]
- \item \options{shadow} \par
- This key determines whether shadows are placed or not. By default, shadows
- are disabled. If not set to \options{no}, this key determines where the
- shadow is placed: at \options{topleft}, \options{topright},
- \options{bottomleft}, or \options{bottomright}. Setting this key to
- \options{yes} puts the shadow at \options{bottomright}.
