@title
Including graphics <span class="emoji">🖼️</span>

@content
To display graphics, we need the `graphicx` package.

``` {.lang-tex .hljs}
\begin{figure}
    \includegraphics{<file path>}
    \caption[<short caption (table of
		figures)>]{<full caption>}
\end{figure}
```

Specifying the size:

``` {.lang-tex .hljs}
\includegraphics[width=0.5\textwidth,
height=5cm]{<file path>}
```


@slide(layout=content-only)

@title
Layout on the page

@content

``` {.lang-tex .hljs}
\begin{figure}[<position code>]
```

LaTeX places graphics automatically. With position codes, we can express our preferences (they can be combined as well).


<table>
	<tr>
		<th style="min-width:4em">code</th>
		<th>position</th>
	</tr>
	<tr class="fragment">
		<td>h</td>
		<td>here, if you don’t mind</td>
	</tr>
	<tr class="fragment">
		<td>t</td>
		<td>top of the page</td>
	</tr>
	<tr class="fragment">
		<td>b</td>
		<td>bottom of the page</td>
	</tr>
	<tr class="fragment">
		<td>p</td>
		<td>on its own page</td>
	</tr>
	<tr class="fragment">
		<td>H</td>
		<td>Here, for God’s sake! <br />(`float` package required)</td>
	</tr>
</table>

Centred alignment

@content
``` {.lang-tex .hljs}
\begin{figure}[<position>]
    \begin{center}
        \includegraphics{<path-to-file>}
    \end{center}
\end{figure}
```

Alternatively:

``` {.lang-tex .hljs}
\begin{figure}[<position>]
    \centering
    \includegraphics{<path-to-file>}
\end{figure}
```
