Output

In LaTeX, using `\\` to force a newline in a caption can indeed lead to errors, particularly when the `hyperref` package is used. This is because `\\` isn't always handled well within moving arguments, such as those in captions. Instead of using `\\` directly, you can use the `\newline` command or the `\par` command. Here is an example of how to use these commands within a caption:

\documentclass{article}
\usepackage{hyperref} % Load hyperref package

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is a caption with a forced newline \newline using the \texttt{\textbackslash newline} command.}
    \label{fig:example}
\end{figure}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is a caption with a forced newline \par using the \texttt{\textbackslash par} command.}
    \label{fig:example2}
\end{figure}

\end{document}
In this example, the `\newline` and `\par` commands are used to introduce new lines in the captions without causing errors. This approach should work without causing the `\Hy@tempa has an extra } runaway argument?` error. If you still encounter issues, consider using the `caption` package, which provides more robust handling of captions:

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is a caption with a forced newline \protect\\ using the \texttt{\textbackslash\textbackslash} command.}
    \label{fig:example}
\end{figure}

\end{document}
In this case, `\protect\\` is used to safely include a newline in the caption. The `caption` package is particularly useful for more advanced customization of captions.

Output

The error you're encountering in LaTeX when you force a newline in a caption using `\\` is likely related to how the `caption` package or the `hyperref` package handles special characters and formatting in captions. Using `\\` directly in captions can sometimes lead to complications, especially when these packages are involved. To address this issue, you can use the `\newline` command instead of `\\` for forcing a newline in captions. Here's an example of how you can do this:

\documentclass{article}
\usepackage{caption}
\usepackage{hyperref}

\begin{document}
\begin{figure}[h]
    \centering
    % Your figure here, e.g., \includegraphics{example.png}
    \caption{This is the first line\newline This is the second line}
    \label{fig:example}
\end{figure}
\end{document}
In the above example, `\newline` is used to create a new line within the caption text. This should avoid the error related to `\Hy@tempa` and runaway arguments. If you still encounter issues, consider ensuring that your LaTeX distribution and packages are up to date. Sometimes, package updates fix underlying compatibility problems. Additionally, if you need more control over formatting within captions, you might also consider using the `\par` command or other formatting commands provided by the `caption` package. For example: 
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
\documentclass{article}
\usepackage{caption}

    \centering
    % Your figure here, e.g., \includegraphics{example.png}
    \caption{This is the first line\par This is the second line}
    \label{fig:example}
\end{figure}
\end{document}
Experiment with these options to see which one works best for your specific document and setup.

Output

The error you are encountering is likely due to the fact that the `\\` command in captions can sometimes cause issues with other packages, especially those related to hyperref or similar. Instead of using `\\` directly in the caption, you can try the following approaches: 1. **Use `\newline` instead of `\\`:** The `\newline` command is often more robust in these situations.

     \caption{This is the first line.\newline This is the second line.}
   \end{figure}
   \end{document}
2. **Use the `\captionsetup` command from the `caption` package:** The `caption` package allows for more fine-tuned control over captions. You can set the width of the caption to force line breaks.

     \captionsetup{width=0.8\textwidth} % Adjust the width as needed
     \caption{This is the first line. This is the second line.}
   \end{figure}
   \end{document}
3. **Use a `minipage` within the caption:** If you need precise control over where the line breaks occur, you can use a `minipage`.

         This is the second line.
       \end{minipage}
     }
   \end{figure}
   \end{document}
If none of these solutions work, make sure that you don't have conflicting packages or settings in your document preamble that might be causing the issue.

Output

The error occurs because the `\\` command is not directly supported in `\caption`. In LaTeX, when you want to force a newline in a caption, you should use the `\newline` command instead. Here is an example: 

 1

\centering
\includegraphics[width=0.5\textwidth]{example-image}
\caption{This is the first line\newline This is the second line}
\end{figure}

\end{document}
In this example, the `\newline` command is used to insert a new line within the caption text. This should work without causing errors related to `\Hy@tempa`. If you need more control over line breaks in captions, you can also use the `\par` command or the `\captionsetup` command from the `caption` package: 
 1
 2
 3

\caption{This is the first line\par This is the second line}
\end{figure}

\end{document}
This should help avoid the error and correctly format your caption text with the desired line breaks.

In LaTeX, the `\\` command for forcing a newline can sometimes cause issues within certain environments, such as captions. This is because the `\\` command is not always compatible with the way captions are processed. Instead, you can use the `\newline` command or package-specific solutions to achieve the desired effect without causing errors. Here are a few methods you can try: 1. **Using `\newline` within the `caption` package:**

Try using one of the above methods to avoid the error you encountered with `\Hy@tempa`. Each method has its own way of handling line breaks in captions, so you can choose the one that best fits your needs.
