After using ConTeXt for a while, many users begin to think about producing
This section of the wiki wants to get you started with presentations in
ConTeXt. There's lots of <s>amazing </s> stuff in the distribution already, such as<s>truly amazing </s> 20-year-old [[Presentation Styles|prebuilt styles ]] for presentations which you can simply use bytyping, e.g.
<texcode>
</texcode>
The styles are fully documented, and you can learn <s>amazing </s> tricks by looking at
the source and the documentation. However, for beginners, it might be easier to
start with a very basic presentation and then slowly add more fancy stuff. This
interactive screen presentations as well.
<texcode>\setuppapersize[S6][S6]</texcode>
</texcode>
Moreover, on slides, you want TeX to be tolerant with its horizontal space
</texcode>
<texcode>\setupinteractionscreen[option=max]</texcode>
will cause launcing the PDF document in full-screen mode. In Acrobat you can use CTRL-L to switch between normal and full-screen mode.
{{todo|write something about them}}
Here is a small example showing how to include hyperlinks: <texcode>\setupcolors[state=start]\setupinteraction[state=start,color= Including Graphics middlered]\useURL [garden][http://contextgarden.net]\starttextThe \from[garden] site is useful.\stoptext</texcode> It looks like this (in a PDF viewer the red link is clickable and should call up a browser on the link when you click it): <context>\setupcolors[state=start]\setupinteraction[state=start,color=middlered]\useURL [garden][http://contextgarden.net]\starttextThe \from[garden] site is useful.\stoptext</context> If you want an alternative text to show up in the clickable area, use the fourth argument to \useURL, like this:<texcode>\setupcolors[state=start]\setupinteraction[state=start,color=middlered]\useURL [garden][http://contextgarden.net][][Context garden]\starttextThe \from[garden] is useful.\stoptext</texcode> It looks like this: <context>\setupcolors[state=start]\setupinteraction[state=start,color=middlered]\useURL [garden][http://contextgarden.net][][Context garden]\starttext The \from[garden] is useful.\stoptext</context> The same technique can be used to add navigation buttons. [[Symbols/nav]] provides the symbol. <texcode>\def\fp{\goto{\symbol[firstpage]}[page(1)]}\setupheadertexts[\fp]</texcode>
<texcodecontext>\externalfiguresetupcolors[namestate=start]\setupinteraction[widthstate=...start]\def\fp{\goto{\symbol[firstpage]%% }[page(probably surrounded by 1)]}\setupheadertexts[\fp]\placefigure)starttextLorem ipsum dolor sit amet.\stoptext</texcodecontext>
== Including Graphics == See [[Using_Graphics]]. == Graphics with Metafun ===
{{todo|how to make page-dependant graphics}}
See [[Animation]] (page is still under construction).
== Compiling Your First Presentation == If you compile a document with these settings, you have something that youcould show as a presentation slide: <texcode>\setuppapersize[S6][S6]\setuppagenumbering[state=stop]\setuptolerance[verytolerant,stretch] \starttext Here's my first presentation in \CONTEXT! Isn't it amazing? \stoptext </texcode> = Refining the Presentation = OK, this is not too impressive yet. The first thing you will want to do isadapt the font size. With a paper size of S6, I find a font size of 20pt aboutright: <texcode>\switchtobodyfont[modern,20pt]</texcode> This looks better. == Colors == Next up: colors. Now I'm aware that the use of colors is an immensely personalchoice -- I've seen people present their slides with a dark gray font on alight gray background, and they seemed very proud of their design. Others usepsychedelic colors that can induce serious sickness. So let's go for a ratherconservative combination of colors. Something I find very readable even inrooms where the lighting is a bit problematic is a white typeface on a bluebackground. So let's add this. Our document will now look like this: <texcode>\setuppapersize[S6][S6]\setuppagenumbering[state=stop]\switchtobodyfont[modern,20pt]\setupcolors[state=start]\setupbackgrounds[page][background=color,backgroundcolor=darkblue]\startcolor[white] \starttext Here's my first presentation in \CONTEXT! Isn't it amazing? \stoptext</texcode> This will give you something to start from. You can now go and build apresentation with this design: make every slide a new page, use all the ConTeXtfeatures (such as lists, itemize, tables, math, chemical formulae, etc.) youwant. == Adding fancier effects == Now when you look at your slides, you will certainly feel that there's room forimprovement. There's only a few things I can mention here; for the rest, have alook at the predefined styles to get some ideas. First, the background. Something I find very attractive is a background thathas different shades, beginning in a very dark blue at the top and ending in anoticeably lighter blue at the bottom. Metafun can easily produce such shadedbackgrounds: <texcode>\definecolor[a][r=0,g=0,b=1]\definecolor[b][r=0,g=0,b=0.05] \startuniqueMPgraphic{LinearShade}path p ;p := unitsquare xscaled \overlaywidth yscaled \overlayheight ;linear_shade(p,6,\MPcolor{a},\MPcolor{b}) ;\stopuniqueMPgraphic \defineoverlay[shaded][\useMPgraphic{LinearShade}] \setupbackgrounds[page][background={shaded}]</texcode> What we have done: defined two colors; a is a very light, b a very dark blue.We let metafun calculate an interpolation between both colors. Try other valuesfor the colors and be amazed! You can also try to set "p,6" to other valuessuch as "p,0" or "p,4." == Adding a Footer == Next, the bottom of our slides. If the audience is apt to forget your name, thetitle of your talk, and the date, you could include this vital information inthe footer of the page. <texcode>\setupfootertexts[{\color[white]{\tfxx \midaligned{\rlap{\currentdate} \hfill TITLE HERE\hfill \llap{YOUR NAME HERE}}}}]</texcode>Don't forget to put<texcode>\setupfooter[state=start]</texcode>into your document where you want the footer to appear first (probably not onthe title of your presentation...). == Adding a Progress Meter == If your audience is able to remember these details, but you suspect they maybe yearning for the end of your presentation, you may want to include a"progress meter" that highlights how many slides they have seen and how manymore they will have to stand. Put this in your preamble: <texcode>\definecolor [InteractionColor] [s=.2]\definecolor [ContrastColor] [s=.5] \setupinteraction [page=yes, color=InteractionColor, contrastcolor=ContrastColor, menu=on, state=start] \setupsubpagenumber [way=bytext, state=start] \setuplayout[bottomspace=.8cm, bottom=12pt] \startinteractionmenu[bottom] {\interactionbar[alternative=f,width=\makeupwidth,height=1ex]}\stopinteractionmenu</texcode>Again, don't forget to put <texcode>\setupinteractionmenu[state=start]</texcode>into your text. Finally, a few things about the placement of pictures. This can be done withthe {{cmd|framed}} command. You probably have to try and adjustdifferent parameters to get exactly what you need, but here's something thatworked for me: == Adding Pictures == In the case of wide pictures, it's fairly easy. You will want them midaligned,and you'll want them to fill as much space of the area between your title andthe footer as possible: <texcode>\midaligned{\externalfigure[NAME][height=.75\textheight]} %Adjust!\vfill</texcode> I found it more difficult to have longish narrow pictures: in that case, Idon't want a title above the picture, but I want it to fill all the verticalspace between the top margin and the footer. I want the text accompanying thepicture opposite it, centered horizontally and vertically. This can be donewith a {{cmd|startcombination}}: <texcode>\setupcombinations[distance=0pt] \setupframed[frame=off,height=.9\textheight,width=.5\textwidth,top=\vss,bottom=\vss,align=middle] \startcombination\framed{\externalfigure[NAME][width=.5\textwidth]}{} %watch the pair of empty braces,\framed{YOUR TEXT GOES HERE}{} % it's essential\stopcombination</texcode> = Post Processing Presentation = Sometimes one wants to give a handout of the presentation, with multiple slides on one page. It is easy to do this using {{cmd|combinepages}} or <code>texexec --pdfcombine</code> To use {{cmd|combinepages}}, suppose that your presentation is <code>slides.tex</code>. Create a file <code>handout.tex</code> with the following content <texcode>\setuppapersize [A4][A4] % or [A4,landscape][A4,landscape] \setuplayout [header=0pt,footer=1cm, backspace=1cm,topspace=1cm, width=middle,height=middle] \setupfootertexts [presentation---\currentdate\space---\space\pagenumber] \starttext \combinepages[slides][nx=2,ny=3,frame=on]\stoptext</texcode>This will give you 2*3 slides on A4 paper. = Additional modules ==
* The [[RawSteps]] module enables you to build a presentation step-by-step without the usage of JavaScript
* <s>[[Stepper]] which is buit in ConTeXt.</s>Broken
* The simple slides module [http://github.com/adityam/simple-slides/tree/master simple-slides] serves too.
* [[Presentation effects]], [[Presentation Styles]], [[SlideWithSteps]]
* See in [[Using Graphics| using graphics]] how to use movies.

If you're interested in presentations, your first stop should be the [http://www.pragma-ade.com/ pragma website]. You can download pdfs with the documented source-code of 18 presentation modules at http://www.pragma-ade.com/dir/general/sources/. To get a first impression of the visual appearance that the prebuilt styles offer, have a look at http://www.pragma-ade.com/show-pre.pdf (big document, ~ 3 MB!). {{Todotodo|collect some + some extremely simple}}

<s>
Here's an Interesting post, written by Maurice Diamantini:

* pdf file '''one pdf page''' for each final step by page
** Good format for printing 2up or 4up slides
** This third output would also allow to print a ''"slide + comment"'' version of the presentation for the speackerspeaker.
The option of texexec could be something like
* In general, I seem to have much more luck with advi then with xdvi for doing slides. It supports all kinds of interactive things. I've been told it can even do plugins (movies and such), but they only have a LaTeX package to support that.

Here are some simple macros almost fully satisfying the idea above with [[SlideWithSteps]], shared with the others by Otared Kavian:
