! \reserved@a 的参数有一个额外的 }。\par } 尝试在标题中包含图形时

Question

我想要author右侧的，所以我使用titling。

\documentclass[a4paper, 12pt, oneside]{report}
\usepackage{graphicx}
\graphicspath{{images/}}
\usepackage[width=150mm, top=12.5mm, bottom=25mm]{geometry}
\usepackage{fancyhdr}

\usepackage{titling}
\pretitle{\begin{center}\LARGE}
\posttitle{\par\end{center}}
\preauthor{\begin{flushright}}
\postauthor{\par\end{flushright}}

\title{
\includegraphics[scale=0.5]{logo.png}\\
Dipartimento di Ingegneria dell'Informazione e Scienze Matematiche\\
\hfill \break
Masters of Science in Computer and Automation Engineering\\
\hfill \break
Thesis
}
\author{NSV}


\begin{document}

    \maketitle
    \include{chapters/chap1}
    \include{chapters/chap2}
    \include{chapters/chap3}
    \include{chapters/chap4}
    \include{chapters/chap5}

\end{document}

! Argument of \reserved@a has an extra }. <inserted text> \par }但我得到了错误! Paragraph ended before \reserved@a was complete.<to be read again>\par }

如果我删除下面的代码，一切都会正常工作，但我将其放在author中心。

\usepackage{titling}
\pretitle{\begin{center}\LARGE}
\posttitle{\par\end{center}}
\preauthor{\begin{flushright}}
\postauthor{\par\end{flushright}}

Answer 1

只是\protect命令\includegraphics。

\documentclass[a4paper, 12pt, oneside]{report}
\usepackage{graphicx}
\graphicspath{{images/}}
\usepackage[width=150mm, top=12.5mm, bottom=25mm]{geometry}
\usepackage{fancyhdr}

\usepackage{titling}
\pretitle{\begin{center}\LARGE}
\posttitle{\par\end{center}}
\preauthor{\begin{flushright}}
\postauthor{\par\end{flushright}}

\title{%
\protect\includegraphics[scale=0.5]{example-image}\\
Dipartimento di Ingegneria dell'Informazione e Scienze Matematiche\\[\bigskipamount]
Masters of Science in Computer and Automation Engineering\\[\bigskipamount]
Thesis
}
\author{NSV}


\begin{document}

    \maketitle

\end{document}

\hfill\break还请注意，您应该使用可选的间距命令来代替\\。

Answer 2

问题是由命令\includegraphics内部引起的\title

您可以\@title通过重新定义来将其包含在内，而不会出现问题\@title：

\documentclass[a4paper, 12pt, oneside]{report}
\usepackage{graphicx}
\graphicspath{{images/}}
\usepackage[width=150mm, top=12.5mm, bottom=25mm]{geometry}
\usepackage{fancyhdr}

\usepackage{titling}
\pretitle{\begin{center}\LARGE}
\posttitle{\end{center}}
\preauthor{\begin{flushright}}
\postauthor{\end{flushright}}

\title{
test\hfill test2 \hfill test3
}
\makeatletter
\let\oldtitle\@title
\def\@title{\includegraphics[scale=0.5]{example-image-a}\\\oldtitle}
\makeatother
\author{NSV}


\begin{document}
    \maketitle


\end{document}

输出：
