Output

The error message you are encountering when trying to force a newline in a caption using `\\` is due to the way LaTeX handles captions, especially with certain packages like `hyperref`. The `\\` command is not always compatible within captions because it can lead to issues with how the caption is processed. To insert a newline in a caption without causing errors, you can use the `\caption` command in conjunction with the `\par` command or the `\newline` command, which are generally safer options. Here’s how you can do it: ### Using `\par`:

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{your-image-file}
    \caption{This is the first line of the caption.\par This is the second line.}
    \label{fig:your-label}
\end{figure}

### Using `\newline`:

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{your-image-file}
    \caption{This is the first line of the caption.\newline This is the second line.}
    \label{fig:your-label}
\end{figure}

### Example with `subcaption`: If you are using the `subcaption` package, you can also use a similar approach:

\begin{figure}
    \centering
    \begin{subfigure}{0.4\textwidth}
        \includegraphics[width=\linewidth]{your-image-file}
        \caption{This is the first line of the caption.\par This is the second line.}
        \label{fig:your-label}
    \end{subfigure}
\end{figure}

### Additional Notes: 1. **Avoiding `\\`:** It's best to avoid using `\\` in captions altogether because it can lead to unexpected behavior, especially in documents that use packages that modify how floats and captions are handled. 2. **Check for Other Packages:** If you're using packages like `caption` or `subcaption`, ensure you are using the latest versions as they might have specific features or fixes related to captions and line breaks. 3. **Document Class Compatibility:** Sometimes the document class you're using may also affect how captions are handled. Always check the documentation for any class-specific recommendations. These methods should help you avoid the "extra }" error while still achieving the desired formatting in your captions.

Output

In LaTeX, using `\\` to force a newline in a caption can lead to issues because the caption text is processed in a restricted way. The error you're encountering, such as `\Hy@tempa has an extra } runaway argument`, often occurs due to the way the caption is handled by the hyperref package, which is commonly used for creating hyperlinks in documents. To properly include line breaks in captions, you can use the `\caption` command along with the `\par` command or the `\newline` command instead of `\\`. Here's how you can do it: ### Using `\par`

\caption{This is the first line. \par This is the second line.}

### Using `\newline`

\caption{This is the first line.\newline This is the second line.}

### Example Here's a complete example of a figure with a caption that includes a newline:

\documentclass{article}
\usepackage{graphicx}
\usepackage{hyperref}

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image} % Replace with your image
    \caption{This is the first line.\newline This is the second line.}
    \label{fig:example}
\end{figure}

\end{document}

### Alternative: Using `caption` package If you need more advanced formatting options for captions, consider using the `caption` package, which allows for more flexibility with line breaks and other features:

\usepackage{caption}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\textwidth]{example-image} % Replace with your image
    \caption{This is the first line.\\ This is the second line.}
    \label{fig:example}
\end{figure}

Using the `caption` package allows `\\` to function correctly in captions without causing errors. ### Conclusion In general, avoid using `\\` directly in captions unless you are using the `caption` package that supports it. Instead, use `\par` or `\newline` to achieve the desired line breaks without errors.

Output

When using LaTeX, forcing a newline in captions using `\\` can lead to issues, especially when using packages like `hyperref` which manage links and reference formatting in your document. The error "extra } runaway argument" typically indicates that LaTeX has encountered an unexpected closing brace, which can happen when it gets confused by the special formatting commands. To avoid this problem, consider using the `\caption` command options or using the `\newline` command instead of `\\`. Here are some strategies to properly handle newlines in captions: ### Using `\protect` with `\\` You can make `\\` work in captions by protecting it with `\protect`:

\caption{This is a caption with a newline\protect\\ and continues here.}

### Using `\newline` Another option is to use `\newline`, which is generally safer in captions:

\caption{This is a caption with a newline\newline and continues here.}

### Using `\par` You can also use `\par` to create a new paragraph:

\caption{This is a caption with a newline\par and continues here.}

### Using `caption` package If you are using the `caption` package, you can use the `\captionsetup` command to allow line breaks in captions:

\usepackage{caption}

\captionsetup{format=plain, singlelinecheck=off} % Allow multiple lines

\caption{This is a caption with a newline\\ and continues here.}

### Example Here is a complete example demonstrating the use of `\protect`:

\documentclass{article}
\usepackage{graphicx}
\usepackage{hyperref}

\begin{document}

\begin{figure}[h]
    \centering
    \includegraphics[width=0.5\linewidth]{example-image}
    \caption{This is a caption with a newline\protect\\ and continues here.}
\end{figure}

\end{document}

By using one of the methods above, you should be able to include newlines in your captions without running into errors.

Output

In LaTeX, using `\\` to force a newline in a caption can lead to issues because the caption is handled differently than regular text. The error you’re encountering is often due to the way that LaTeX processes captions, especially with packages like `hyperref` involved. To insert a line break in a caption, you can use the `\caption` command along with the `\parbox` or `\multirow` command, or you can define your own command for line breaks in captions. Here are a few approaches you can take: ### Method 1: Using `\parbox` You can use `\parbox` to encapsulate your caption text:

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{image.png}
    \caption{\parbox{8cm}{This is the first line of the caption.\\ This is the second line of the caption.}}
    \label{fig:example}
\end{figure}

### Method 2: Using `\caption*` If you are using `caption` package, you can use `\caption*` for unnumbered captions which can contain line breaks:

\usepackage{caption}

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{image.png}
    \caption*{This is the first line of the caption.\\ This is the second line of the caption.}
    \label{fig:example}
\end{figure}

### Method 3: Using the `caption` package with `\newline` If you are using the `caption` package, you can use `\newline` instead of `\\`, which is compatible with captions:

\usepackage{caption}

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{image.png}
    \caption{This is the first line of the caption.\newline This is the second line of the caption.}
    \label{fig:example}
\end{figure}

### Method 4: Using `\linebreak` Another alternative is using `\linebreak`:

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{image.png}
    \caption{This is the first line of the caption.\linebreak This is the second line.}
    \label{fig:example}
\end{figure}

Choose any of the above methods based on your needs and the packages you have included in your document. These methods should help you avoid the error and allow you to format your captions as desired.

Output

In LaTeX, using `\\` to force a newline in a caption can lead to issues because captions are often processed in a way that doesn't handle newlines gracefully. The error you're encountering (`\Hy@tempa has an extra } runaway argument`) is likely due to the fact that the caption text is not being properly parsed when you introduce a line break. To insert a newline in a caption without causing errors, you can use the `\caption` command along with the `\par` command or the `\newline` command. Here's how you can do it: ### Method 1: Using `\par` You can use `\par` to create a new paragraph within the caption:

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption{This is the first line of the caption.\par This is the second line.}
    \label{fig:example}
\end{figure}

### Method 2: Using `\newline` Alternatively, you can use `\newline`:

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

### Method 3: Using `\caption*` (if available) If you're using a package like `caption`, you might have access to `\caption*`, which can also handle newlines better:

\usepackage{caption}

\begin{figure}
    \centering
    \includegraphics[width=0.5\textwidth]{example-image}
    \caption*{This is the first line of the caption.\\ This is the second line.}
    \label{fig:example}
\end{figure}

### Summary When adding newlines in captions, avoid using `\\`. Instead, use `\par` or `\newline`, or check if you can use the `caption` package for additional features. This will help you avoid errors and ensure that your captions are formatted correctly.
