在 LaTeX 中对齐页眉

Question

如何将文本对齐到标题的中心和日期，在水平线下方，

\documentclass{letter}

\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{geometry}
\usepackage{lipsum}

\geometry{headheight = 35pt}
\fancypagestyle{firstpage}{\fancyhf{}\fancyhead[C]{\includegraphics[scale=0.35]{pecemblem}}\textsc{Pondicherry Engineering College\\ \textsc{Pillaichavady}\\ \textsc{Puducherry-605014}}} 
%\fancypagestyle{plain}{\fancyhf{}\fancyhead[C]{\includegraphics[height=0.5in]{pecemblem}}}
\pagestyle{plain}
\begin{document}%
    \begin{letter}{}%
        \opening{Dear Some Name,}
        \lipsum[1-10]
    \end{letter}%
\end{document}%

Answer 1

再次调整headheight和top、 和的值scale。

此外，所有带有的行都\textsc必须放在括号内\fancyhead

平均能量损失

\documentclass{letter}

\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{geometry}
\usepackage{lipsum}

\geometry{headheight=6cm,top=8cm}
\fancypagestyle{firstpage}{\fancyhf{}\fancyhead[C]{\includegraphics[scale=1.2]{pecemblem}\\
\textsc{Pondicherry Engineering College}\\ \textsc{Pillaichavady}\\ \textsc{Puducherry-605014}}}
%\fancypagestyle{plain}{\fancyhf{}\fancyhead[C]{\includegraphics[height=0.5in]{pecemblem}}}
\pagestyle{plain}
\begin{document}%
    \begin{letter}{}%
        \opening{Dear Some Name,}
        \lipsum[1-10]
    \end{letter}%
\end{document}% 

输出

无论如何，我会选择一个不涉及标题的解决方案，如下所示：

\documentclass{letter}

\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{geometry}
\usepackage{lipsum}

\fancypagestyle{plain}{\fancyhf{}\fancyhead[C]{\includegraphics[height=0.5in]{pecemblem}}}
\pagestyle{plain}

\begin{document}%
    \begin{letter}{}%

        \begin{center}
        \includegraphics[scale=1.2]{pecemblem}\\
        \textsc{Pondicherry Engineering College}\\
        \textsc{Pillaichavady}\\
        \textsc{Puducherry-605014}\\
        \hrulefill
        \end{center}

        \opening{Dear Some Name,}     
        \lipsum[1-10]
    \end{letter}%
\end{document}% 

输出
