|| Slide:
|| Hello and welcome to the spoken tutorial on '''Beamer Themes and Animation'''

|-
|| Slide: '''Learning Objectives'''
|| In this tutorial, we will learn to,

# Use '''Beamer themes'''
# Do '''text animations''' using '''Overlay''' 

|-
|| '''Slide 3: System Requirements'''
|| This tutorial is recorded using

* '''Windows 11''' and
* '''TeXworks''' editor v0.6. 

The steps demonstrated will work in all operating systems.

|-
|| '''Slide 4: Prerequisites'''
||

* To practise this tutorial, you should be familiar with '''LaTeX commands.'''
* You should also know how to create a presentation using '''Beamer'''.

|-
|| '''Slide 5: Code Files'''
||
* The files used in this tutorial are available in the '''Code files''' link on this tutorial page.
* Please download and extract the files
* Make a copy and use them for practising. 

|-
|| Slide: '''Demonstration'''
|| For this demonstration, I will be using the '''Beamer theme Matrix'''.

The same is available at this link:-

[https://hartwork.org/beamer-theme-matrix/ https://hartwork.org/beamer-theme-matrix/] 

Open a '''web browser''' and go to this '''URL'''. 

|-
|| <nowiki>[Firefox] Show the beamer page</nowiki>

Navigate row-wise on the left

Navigate column-wise on the top

Hover the mouse on any one of the theame
|| '''Theme matrix''' shows various '''themes''' and '''color theme '''combinations included with the '''Beamer class'''. 

The rows of the '''matrix''' show the list of the different '''Beamer themes'''.

The columns of the '''matrix''' show the list of the different '''Beamer color themes. '''

When the cursor is placed over an image, it shows the corresponding '''theme '''and '''color theme'''.

|-
|| Go to '''Downloads''' folder >> '''Beamer-Code-Files'''
|| Go to the folder where all the '''Code files''' are downloaded on your machine.

|-
|| Open '''beamerThemesAndAnimation.tex''' in TeXworks
|| Open the file '''beamerThemesAndAnimation.tex''' in '''TeXworks editor'''.

We will see some '''LaTeX code''' written in the file.

|-
|| 
|| Let’s try to understand the '''code'''.

|-
|| Highlight: '''\usetheme{Warsaw}'''
|| '''\usetheme{Warsaw} '''is added to the preamble to use the '''Warsaw theme''' in '''Beamer'''. 


'''Warsaw theme '''displays a header on the '''pdf''' slide.

|-
|| Highlight:''' \section and \subsection'''
|| In the document, I have inserted the '''\section''' and '''\subsection''' before each '''frame''' begins.

|-
|| Highlight the '''section''' and '''subsection''' names
|| The '''section''' and '''subsection''' names will be displayed in the header of the slide.

|-
|| At the top left drop-down >> select '''pdfLaTeX'''
|| At the top left, in the drop-down select '''pdfLaTeX,''' if not already selected.

|-
|| Click on the green arrow button
|| Then click on the green arrow button to '''compile''' the file.


'''Compile''' the file once again to update the '''theme'''.

|-
|| Point to the pdf output
|| On '''compilation''', we get the '''pdf''' output with the '''Warsaw theme'''.

|-
|| Highlight the header


Highlight the section names
|| In the slide, we can see a header.


It says '''Beamer Themes''' and '''Introduction, '''one below the other.

|-
|| Highlight the section names in the TeXworks file.
|| These are the names we defined in the '''sections'''.

|-
|| Point to the green right arrow in the output window
|| In the output window, go to the next slide using the green-coloured right arrow.

|-
|| Point to the top section.


Click on “'''Color Themes'''”
|| Look at the header portion of the '''pdf slide.'''


'''Section '''name''' “Beamer Themes”''' is seen on the left banner.


And the '''subsection '''name '''“Themes” '''is seen on the right banner.

|-
|| Highlight the section and subsection names in the TeXworks file.
|| These are the names we defined in the '''sections '''and '''subsections'''.

|-
|| Highlight the '''section''' or '''subsection''' names. 
|| You can go to any slide by clicking on the '''section''' or '''subsection''' names. 

|-
|| Click on '''Color Themes'''
|| Click on '''Color Themes''' on the top right banner.

|-
|| Point to the pdf output 

Slide: '''Beamer Themes Color Themes'''
|| The respective '''section''' name and '''subsection''' name of the slide you are on, get highlighted. 


In my case, '''Beamer Themes''' and '''Color Themes''' get highlighted. 

|-
|| Point to the pdf output

Slide: Introduction
|| Let’s click on '''Introduction'''. 


We are directed to the '''Introduction''' slide.

|-
|| Only Narration
|| So, this part sort of behaves like a '''navigation panel'''.

|-
|| Back to '''beamerThemesAndAnimation.tex'''
|| Let’s go back to the '''code'''.

|-
|| <nowiki>[TeXworks]</nowiki>
|| '''Beamer themes''' can be combined with a '''color theme.''' 

|-
|| <nowiki>[TeXworks] </nowiki>Type:

'''\usecolortheme{beaver}'''
|| To do so, before the '''begin document command, '''type the '''code '''as shown.

|-
|| <nowiki>[TeXworks] Highlight</nowiki>


'''\usetheme{Warsaw}'''

'''\usecolortheme{beaver}'''
|| Always put the '''\usecolortheme command''' below the '''\usetheme command'''.

|-
|| Compile twice
|| Now '''compile''' the file twice.

|-
|| Point to the pdf output



|| Observe the output. 


'''colortheme command''' changed the '''color''' used for different '''elements'''. 


Let’s go back to the '''code'''.

|-
|| <nowiki>[TeXworks] Update</nowiki>


'''\usetheme{Madrid}'''

'''\usecolortheme{crane}'''
|| Let’s try another '''theme''' and '''theme color.''' 


Update the '''\usetheme''' and '''\usecolortheme''' as shown.

|-
|| <nowiki>[TeXworks] Highlight</nowiki>


\usetheme{Madrid}


\usecolortheme{crane}
|| I have set the '''theme '''to '''Madrid '''and the '''colortheme''' to '''crane.'''

|-
|| Compile twice
|| '''Compile''' the file twice.

|-
|| Point to the pdf output
|| We can see the generated '''pdf''' output.


It has the '''Madrid theme''' along with the''' crane colortheme.'''

|-
|| 
|| Next, we will see how to add''' Text Animation''' on the slides.

|-
|| Slide: '''Overlays'''
||
* '''Overlay''' is a term used by the '''Beamer document class''' to describe the '''layering''' of slides.
* There are a number of '''commands''' that enable us to use '''overlays '''on''' text'''. 

|-
|| Only narration
|| Let’s see important '''overlays''' one by one.


Switch to the '''text editor'''.

|-
|| <nowiki>[TeXworks] Update the code:</nowiki>


\section{Animation}

\subsection{onslide command}

\begin{frame}

\frametitle{Overlay: onslide}

<nowiki>\onslide<1->{First Line of Text} \\</nowiki>

<nowiki>\onslide<2->{Second Line of Text} \\</nowiki>

<nowiki>\onslide<3->{Third Line of Text}</nowiki>

\end{frame}
|| Replace the '''document section code''' as shown here.




|-
|| <nowiki>[TeXworks] Highlight</nowiki>


<nowiki>\onslide<number-></nowiki>
|| The number inside the angle brackets tells '''LaTeX''' which slides the '''item''' should appear on. 


'''hyphen''' is used for '''continuation'''. 

|-
|| Compile
|| On '''compilation,''' we get the output as seen here.

|-
|| Point to the pdf output

Slide: Animation on onslide 
|| In the generated '''pdf''', click on the green right arrow to go to the next page. 


Observe that our three lines of text are appearing one by one in a sequential order.

|-
|| Back to '''beamerThemesAndAnimation.tex'''
|| Switch to the '''editor '''once again.

|-
|| <nowiki>[TeXworks] Type:</nowiki>


\setbeamercovered{transparent} 
|| Let’s make the '''text''' transparent on an unspecified slide. 


Next to the line '''\frametitle''' type the '''code''' as shown here.

|-
|| Compile
|| '''Compile''' the file.

|-
|| Point to the pdf output
|| Observe the output.


The upcoming slide texts appear as transparent text.

|-
|| <nowiki>[TeXworks] Type:</nowiki>


\subsection{uncover command}

\begin{frame}

\frametitle{Overlay: uncover}

\setbeamercovered{transparent}

<nowiki>\uncover<1> { First Line of Text} \\</nowiki>

<nowiki>\uncover<3> {Third Line of Text} \\</nowiki>

<nowiki>\uncover<2> { Second Line of Text} \\</nowiki>

<nowiki>\uncover<5> {Fifth Line of Text} \\</nowiki>

<nowiki>\uncover<4> {Fourth Line of Text}</nowiki>

\end{frame}
|| In the '''tex '''file, before the '''\end{document} command''' type the '''code''' as shown here. 




|-
|| <nowiki>[TeXworks] </nowiki>Highlight: 


'''\uncover'''<nowiki><1></nowiki>
|| Observe that here we have used''' \uncover''' instead of '''\onslide'''.


'''\uncover''' is with a digit present within angular brackets.


This will display the '''text''' on the slide depending on the number given here. 


Notice that, here we have also changed the order of appearance of the text.

|-
|| Compile
|| '''Compile''' the file

|-
|| Point to the pdf output

slide: Animation \uncover command 
|| Using the '''navigation''' arrow, go to the slide''' Animation \uncover command.'''


Here only one out of five '''line items '''is appearing on the slide and the rest are transparent.


When you further '''navigate''', it displays the third item instead of the second item.

|-
|| <nowiki>[TeXworks] </nowiki>Highlight


<nowiki>\uncover<3> {Third Line of Text} \\</nowiki>

<nowiki>\uncover<2> { Second Line of Text} \\</nowiki>
|| This is because in the '''code''' the third '''item''' is mentioned as the second '''item.'''


And the second '''item''' is mentioned as the '''third''' item using the '''\uncover command.'''

|-
|| <nowiki>[TeXworks] Type:</nowiki>


\subsection{only command}

\begin{frame}

\frametitle{Overlay: only}

<nowiki>\only<1>{First Line of Text}</nowiki>

<nowiki>\only<2>{Second Line of Text}</nowiki>

<nowiki>\only<3>{Third Line of Text}</nowiki>

\end{frame}
|| In the '''tex '''file, before the '''\end{document} command''', type the '''code''' as shown here. 




|-
|| <nowiki>[TeXworks] </nowiki>Highlight


<nowiki>\only<></nowiki>
|| The '''command \only''' works exactly like the '''\uncover command'''. 


The only exception is that it does not reserve any space for the hidden '''text'''. 

|-
|| Compile
|| '''Compile''' the file.

|-
|| Point to the pdf output 

slide: Animation \only command
|| Go to the slide''' Overlay: only command.'''


While '''navigating''' to the right, we can see only the respective '''item, '''and not the''' '''other '''items'''.


Also, all the '''items '''are appearing in the same '''line'''.

|-
|| 
|| This is how we can customize '''LaTeX''' slides as per our requirement.

|-
|| Only narration
|| With this, we have come to the end of this tutorial.
