如何从乳胶中的侧边栏中删除作者的名字？

Question

我用乳胶写我的演示文稿(用overleaf.com)。我不想把作者的名字添加到下面给出的铰刀右侧的垂直栏中，

​

​

我还提供了标题页的乳胶码，如下所示：

\documentclass[14pt,aspectratio=169]{beamer}
\usetheme{Marburg}
\graphicspath{{Arquivos/}}
\usepackage[utf8]{inputenc}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}

\title{Image and Audio Hybrid Watermarking against Synchronization Attacks}
\author{Bhavneet Sharma (31703102)\\[\baselineskip] \small{{Supervised By}
  \and\\Prof. Dr. Mayank Dave}}
%\setbeamercovered{transparent} 
\institute{\includegraphics[width=2cm, height=1cm]{NITKKR_logo.png}
\\National Institute of Technology, Kurukshetra
}
\date{September 22, 2019} 
%\subject{} 
\begin{document}

\begin{frame}
\titlepage
\end{frame}

我的垂直栏，只要求标题的第一页然后开始介绍。

​

​

我不知道该怎么做。帮助解决这个问题。

Answer 1

在beamer中，您可以使用另一个较短的作者名称(对演示文稿标题或机构也是如此)。

\author[Short name]{Author loooong name}

如果这样做，短名称将使用在边(或底部取决于您的主题)栏。因此，要解决您的问题，只需声明一个空的短名称就足够了。

\documentclass[14pt,aspectratio=169]{beamer}
\usetheme{Marburg}
\graphicspath{{Arquivos/}}
\usepackage[utf8]{inputenc}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}

\title{Image and Audio Hybrid Watermarking against Synchronization Attacks}
\author[]{Bhavneet Sharma (31703102)\\[\baselineskip] \small{{Supervised By}
  \and\\Prof. Dr. Mayank Dave}}
%\setbeamercovered{transparent} 
\institute{%\includegraphics[width=2cm, height=1cm]{NITKKR_logo.png}\\
  National Institute of Technology, Kurukshetra
}
\date{September 22, 2019} 
%\subject{} 
\begin{document}

\begin{frame}
\titlepage
\end{frame}
\begin{frame}
\section{This is section 1}
\end{frame}
\begin{frame}
\section{and this is section 2}
\titlepage
\end{frame}
\end{document}

Answer 2

不幸的是，侧栏主题不会测试作者名是否为空，并且无论如何都会插入它。这将为侧栏添加一个不必要的空行。

要真正去掉侧栏中的作者名称，on可以稍微重新定义侧栏模板：

\documentclass[14pt,aspectratio=169]{beamer}
\usetheme{Marburg}
\graphicspath{{Arquivos/}}
\usepackage[utf8]{inputenc}
\usepackage[portuguese]{babel}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
%\usepackage{graphicx}

\title{Image and Audio Hybrid Watermarking against Synchronization Attacks}
\author[]{Bhavneet Sharma (31703102)\\[\baselineskip] {\small {Supervised By}
  \and\\Prof. Dr. Mayank Dave}}
%\setbeamercovered{transparent} 
\institute{\includegraphics[width=2cm, height=1cm,keepaspectratio]{example-image-duck}
\\National Institute of Technology, Kurukshetra
}
\date{September 22, 2019} 
%\subject{} 

\makeatletter
\setbeamertemplate{sidebar right}
  {
    \beamer@tempdim=\beamer@sidebarwidth%
    \advance\beamer@tempdim by -6pt%
    {\usebeamerfont{title in sidebar}%
      \vskip1.5em%
      \hskip3pt%
      \usebeamercolor[fg]{title in sidebar}%
      \insertshorttitle[width=\beamer@tempdim,center,respectlinebreaks]\par%
      \vskip1.25em%
    }%
%    {%
%      \hskip3pt%
%      \usebeamercolor[fg]{author in sidebar}%
%      \usebeamerfont{author in sidebar}%
%      \insertshortauthor[width=\beamer@tempdim,center,respectlinebreaks]\par%
%      \vskip1.25em%
%    }%
    \insertverticalnavigation{\beamer@sidebarwidth}%
    \vfill
    \ifx\beamer@sidebarside\beamer@lefttext%
    \else%
      \usebeamercolor{normal text}%
      \llap{\usebeamertemplate***{navigation symbols}\hskip0.1cm}%
      \vskip2pt%
    \fi%
  }%
\makeatother

离题：

• 您不需要用beamer加载graphicx包，beamer已经加载了它
• 语法\small{...}是错误的。字体大小命令是开关，不带参数，应该是{\small ...}
• 如果您同时指定图像的高度和宽度，它很可能会被扭曲。最好只指定高度或宽度，或者添加keepaspectratio选项
