使用自定义的投影仪主题在rmarkdown :: beamer_presentation中创建从徽标到目录幻灯片的超链接

问题描述

我在 rmarkdown :: beamer_presentation 中使用了自定义的 LaTex投影仪主题.根据这些SO答案(

我尝试过的方法:在 beamerouterthemeTHEMENAME.sty

中定义自定义脚线

  \ mode< presentation>...脚线百分比\ setbeamertemplate {footline} {\ leavevmode％\ hyperlink {目录---目录} {\ includegraphics [width = 12mm，trim = 0mm 0.4mm 0mm 0mm] {img/my_logo.png}}\ hfill\hyperlinkappendixstart{\insertframenumber/\inserttotalframenumber}\ vspace {3mm}}\ mode< all> 

有关完整的MWE，请参阅我的.

解决方案

在正常的投影仪代码中，您可以简单地在框架上附加标签，但是Rmarkdown看起来太愚蠢，无法正确解析 \中的方括号\开始{frame} [label = outline] ....烦人！

作为解决方法，您可以使用诸如节名之类的内容，降价会自动为其插入标签:

  ---副标题:具有R-markdown的光束预视"研究所:某处"日期:`r format(Sys.time()，'％​​B％d，％Y')`"；作者:唐老鸭"输出:#beamer_presentation:默认bookdown :: pdf_book:base_format:rmarkdown :: beamer_presentation#包括:#in_header:preamble.tex主题:"THEMENAME"；latex_engine:xelatex目录:假slide_level:2keep_tex:是标头包括:-\ AtBeginDocument {\ title {MWE} \ titleframe}-\ AtEndDocument {\ begin {closingframe} lalala \ end {closingframe}}-\ makeatletter \ beamer @ ignorenonframefalse \ makeatother---```{r setup，include = FALSE}knitr :: opts_chunk $ set(echo = FALSE)```##大纲{.unnumbered}\目录# 部分##带子弹滑<！-=======================================================--子弹1-第2弹-子弹3<！-附录-><！-=======================================================-```{=乳胶}\ end {frame}\附录\ begin {frame}``` 

并在底线使用此目标

 ％足迹\ setbeamertemplate {footline} {\ leavevmode％\ hyperlink {outline} {\ includegraphics [width = 12mm，trim = 0mm 0.4mm 0mm 0mm] {example-image}}\ hfill\hyperlinkappendixstart{\insertframenumber/\inserttotalframenumber}\ vspace {3mm}} 

I use a custom LaTex beamer theme in an rmarkdown::beamer_presentation.As per these SO answers (LaTex theme, colon, theme path), I used several modifications of the YAML header and beamerthemeTHEMENAME.sty.These LaTex hacks are necessary to apply the LaTex Beamer theme smoothly in the rmarkdown::beamer_presentation.

For the foot line defined in beamerouterthemeTHEMENAME.sty, it would be very nice to have a hyperlink from the logo to the table of contents slide (like the slide numbers are linked to the appendix).

What I tried: define custom foot line in beamerouterthemeTHEMENAME.sty

\mode<presentation>

...

% Foot line
\setbeamertemplate{footline}{
    \leavevmode%
    \hyperlink{toc---table-of-contents}{\includegraphics[width=12mm,trim=0mm 0.4mm 0mm 0mm]{img/my_logo.png}}   
    \hfill
    \hyperlinkappendixstart{\insertframenumber/\inserttotalframenumber}
    \vspace{3mm}
}

\mode<all>

For a complete MWE, see my SO question here.

解决方案

In normal beamer code, you could simply attach a label to the frame, but Rmarkdown seems to be too stupid to correctly parse the square brackets in \begin{frame}[label=outline].... annoying!

As a workaround you could use something like a section name for which markdown will automatically insert a label:

---
subtitle: "Beamer presnetation with R-markdown"
institute: "some place"
date: "`r format(Sys.time(), '%B %d, %Y')`"
author: "Donald Duck"
output:
  # beamer_presentation: default
  bookdown::pdf_book:
    base_format: rmarkdown::beamer_presentation
    # includes:
    #   in_header: preamble.tex
    theme: "THEMENAME"
    latex_engine: xelatex
    toc: false
    slide_level: 2
    keep_tex: true 
header-includes:
  - \AtBeginDocument{\title{MWE}\titleframe}    
  - \AtEndDocument{\begin{closingframe}lalala\end{closingframe}}
  - \makeatletter\beamer@ignorenonframefalse\makeatother
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
```

## Outline {.unnumbered}

\tableofcontents

# section

## Slide with Bullets
<!-- ======================================================== -->

- Bullet 1
- Bullet 2
- Bullet 3

<!-- Appendix -->
<!-- ======================================================== -->
``` {=latex}
\end{frame}
\appendix
\begin{frame}
```

and use this target in the footline

% Footline
\setbeamertemplate{footline}{
    \leavevmode%
    \hyperlink{outline}{\includegraphics[width=12mm,trim=0mm 0.4mm 0mm 0mm]{example-image}}
    \hfill
    \hyperlinkappendixstart{\insertframenumber/\inserttotalframenumber}
    \vspace{3mm}
}
