In this video we will learn how to make latex presentations.And when we say that we are
making presentations in Latex It means that we are using some of the themes in Latex,
we dont usually program each and every element of the theme or we don't normally program
even the templates of a theme.
So what we do is we try to make use of the themes which are available to us and there
are so many themes available and then we have so many options to change the template and
the elements of the presentation that we don't have to program in Latex ever.
So this is a sample presentation which I already have shown to you and all the functions which
this has and the purpose of this video is to show you how you can change the themes
and what are the themes available and how they effect the elements of the presentation.
So first of all you should understand that all these functionalities and everything which
is inside a presentation is called the element of a presentation and these elements are governed
by certain themes.
For example this is the dashboard which shows the progress of the presentation and it has
a certain format.
Sometimes one frame can have more than one slides, so on the right lower bottom, you
can see that there is a progress bar, so you hould understand what element it is called
and then how to modify that element or how to change the color of that element.
So, these three elements at the bottom are called pallets.
So blue one on the right is called the primary pallet, the middle is called the secondary
palletand the pallet on the left is called the tertiary pallette.
SOme themes offer two pallets, some offer three pallets
and some offer four pallets.
So, you have to check the theme which theme you want and then you can see which best suits
your application.Because no one has used all the themes.
For example I have mostly used three or four themes which I like.
I have tested many themes but mostly I use three or four themes, so I know those three,
four themes better than any other themes, so you might not like those themes, so it
depends on you, what type of theme you need.
SO in this video, i will briefly introduce to you what are the themes and what elements
they affect.
So these are some of the presentation themes in Latex.
SO, these themes are divided into five different classes.
So, first themes list on the left, these themes do not have the navigation bar at the top.
So in these you dont see the progress of your presentation.
Then there are themes which have a tree-like navigation bar.n which you get a connected
sections, subsection on the left corner then there are themes with table of content sidebar
which you have on the left hand side.
You have a Table of contents on your presentation.
Then there are themes with mini-frame navigation and also themes with sections and subsection
tables in which you have all the sections and subsections showing at the top of your
presentation.
So, the best way to understand these themes is I'll show you in a minute that is very
simple just a command to change the theme, so you just change the name of the theme in
usetheme command. and you will instantly see the difference how a theme without a navigation
bar looks like and how a theme with a table of contents sidebar looks like.
With just changing a single name of the theme in one command, you can see all these effects.
These are the five theme types in the beamer package.
beamer is the package in which we make latex presentations.
There are some themes called presentation themes and I have already shown these themes
earlier to you.
SO there are five theme types in beamer.
Some are called presentation themes, some are called color themes then font themes,
outer thems and inner themes.
So the presentation themes are those thems which control alol the elements in a presentation.
They control all the elements in the presentation.
Then the color themes.
Color themes dictate colors, so which color are used in a particular theme.
Then there are font themes which dictates the fonts and their attributes.
Then there are outer themes and when we say outer, outer means anything which is outside
the main text.So main text is usually inside the frame.
So everything outside the frame is controlled by outer themes such as headlines, footlines
sidebars or frame titles.
While inner themes control everything which is inside the text.
And inside the text means, i have shown you already...in my previous lecture that there
are some blocks such as the "example blocks", "alert blocks", so all these types of blocks
are isdie the text.
So, these are controlled by inner themes.So you can select a presentation theme, then
you can also select a color theme, outer theme or inner theme, so this gives you a lot of
combinationsbecause there are ten to fifteen presentation themes then there are seven to
ten may be color themes and outer and inner themes are also ten to fifteen.
So you can calculate that how many combinations you have, so in normal circumstances, you
will never need to program anything and you never need to hard-code anything.
This course is also not for this type of advanced use.
So we will only discuss how to use these themes and how to change certain colors, certain
main elements of the presentations.
