帧编号

帧编号

我想更改此投影仪文档的编号:

\documentclass[landscape,9pt]{beamer}                           % COMANDI INIZIALI
\usepackage[italian]{babel}                             % sillabazione italiana
\usepackage[utf8]{inputenc}                             % Per le lettere accentate IN UNIX E IN WINDOWS
\usepackage{ragged2e}                                   % giustifica
\usepackage{amsmath}                                    % Per allineare le equazioni
\usepackage{amssymb}                                    % Per le lettere dell'indicatrice (mathbb)
\usepackage{graphicx} 
\usepackage[export]{adjustbox}
\usepackage[misc,geometry]{ifsym}

\renewcommand{\fontsubfuzz}{1.1pt}                          % Elimina i warning inutili

\begin{document}

\begin{frame}
Title
\end{frame}

\begin{frame}
Frame 1
\end{frame}

\begin{frame}
Frame 2

\begin{frame}
Last Frame

\end{document}

我想要的是:

  1. 第一帧和最后一帧没有编号
  2. 第二帧中的 1/2
  3. 第三帧 2/2

我如何更改帧编号?

答案1

有一次,我想让观众在演讲时猜测帧号的顺序,但这个顺序不是随机的。同样的技巧在这里也适用。

正如你所做的那样,你需要更改模板footline。你所拥有的帧编号由命令控制

\insertframenumber{} / \inserttotalframenumber

并且足以用类似的东西来代替它们

\ifcase\value{framenumber} \or \or 1/2 \or 2/2 \or \fi

这里,是一个 TeX 原语,其功能类似于 switch 语句,在遍历值时\ifcase根据 的值执行不同的操作, --因此上面的代码跳过了和的值。这里,我已经根据您的问题硬连线了和 ,但您可能希望在这里使用 的变体。framenumber0,1,2,3,...\or \orframenumber011/22/2\inserttotalframenumber

为了完整起见,这是完整的示例:

\documentclass[landscape,9pt]{beamer}                           % COMANDI INIZIALI
\usepackage[italian]{babel}                             % sillabazione italiana

编辑 为了使第一帧和最后一帧实际上不编号,而其余幻灯片从 1 开始向上编号(如评论中所要求的那样),请用footline以下内容替换该片段:

\makeatletter
\usepackage{etoolbox}
\addtocounter{framenumber}{-1}
\newcounter{realtotalframenumber}
\setbeamertemplate{footline}
{
% strangely \inserttotalframenumber only appears to be defined here
\defcounter{realtotalframenumber}{\inserttotalframenumber-1}
  \leavevmode%
  \hbox{%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
    \usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
  \end{beamercolorbox}%
  \begin{beamercolorbox}[wd=.5\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
    \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
    \ifnum\c@framenumber=0\relax
    \else
    \ifnumcomp{\value{framenumber}}>{\value{realtotalframenumber}}{\relax}
              {\arabic{framenumber}/\arabic{realtotalframenumber}}
    \fi
    \hspace*{2ex}
  \end{beamercolorbox}}%
  \vskip0pt%
}
\makeatother

这是一个使用计数器的更自动化的解决方案。
