投影机、标题页、徽标和水平线

Question

我有一个投影仪演示文稿，在这里（框架标题文本的字体和位置) 我得到了帮助，定义了正确的 frametitle 环境。现在，我希望在标题页上也拥有水平线和徽标（如果可能的话，大约在同一位置，见下图）。我尝试使用“%\textcolor{red}{\rule{16cm}{1mm}}”并在标题页上创建一个空的 frametitle 环境，但这没有任何结果。

我使用的背景图片：https://images.pexels.com/photos/1323550/pexels-photo-1323550.jpeg和现在的代码

\documentclass[mathserif,11pt]{beamer}

\setbeamercolor{frametitle}{fg=Black}
\setbeamercolor{lower separation line head}{bg=red}

\usepackage{fontspec}
\usepackage{lipsum}
\usepackage{hyperref,graphicx}
\definecolor{mycolor}{rgb}{0.722, 0.435, 0.698}% Rule colour
\newfontfamily{\arialblack}{Arial Black}
\setbeamerfont{frametitle}{family=\arialblack}

\makeatletter
\setbeamertemplate{frametitle}{%
  \nointerlineskip%
    \vskip0.3cm%
   \begin{beamercolorbox}[wd=\textwidth]{frametitle}%
    \begin{minipage}[t][1.2cm][b]{\dimexpr\paperwidth-4.6cm\relax}%
        \usebeamerfont*{frametitle}\insertframetitle%
        \ifx\insertframesubtitle\@empty%
          \strut\par%
        \else
          \par{\usebeamerfont*{framesubtitle}{\usebeamercolor[fg]{framesubtitle}\insertframesubtitle}\strut\par}%
        \fi%%
    \end{minipage}%
    \hfill%
    \begin{minipage}[t][1.2cm][b]{2.5cm}
      \hfill\includegraphics[height=1.2cm]{example-image-b}%
    \end{minipage}%
  \end{beamercolorbox}%
  \begin{beamercolorbox}[colsep=1.5pt,wd=\textwidth]{lower separation line head}
  \end{beamercolorbox}

Answer 1

无论如何，当您加载 tikz 包时，您可以使用它来设计您的标题页背景。

其他的建议：

• 该mathserif选项已过时，请\usefonttheme[onlymath]{serif}改用

• 您不需要加载hyperref和graphicx包，Beamer 会为您加载它们

• 如果您希望所有框架上都有线条和徽标，我不会将它们作为框架标题的一部分，而是使用标题。
