仅在ioslides RStudio中的第一张(主)幻灯片上添加徽标 [英] add logo only on first (main) slide in ioslides RStudio

问题描述

我正在RStudio中使用ioslides(rmarkdwon)从R创建演示文稿.我想添加徽标，但仅添加到呈现此信息的第一张幻灯片(主)上:

I'm using ioslides (rmarkdwon) in RStudio to create the presentation from R. I would like to add the logo, but only to the first slide (main) which renders this information:

---
title: "Presentation"
author: "Tom Hanks"
output: ioslides_presentation
logo: logo.jpg
---

我不希望徽标出现在每张幻灯片的左下角.谁能告诉我如何将其关闭?

I don't want the logo in the bottom-left footer of each slide. Can anyone tell me how to switch it off?

推荐答案

您可以修改ioslide模板，以删除每页上徽标的重复.在rmarkdown github存储库上下载模板 或在计算机上找到您的本地版本.删除以下部分:

You could modify the ioslide template to remove the repetition of the logo on each page. Download the template on the rmarkdown github repository or find your local version on your computer. Remove the following part:

$if(logo)$
    slides > slide:not(.nobackground):before {
      font-size: 12pt;
      content: "";
      position: absolute;
      bottom: 20px;
      left: 60px;
      background: url($logo$) no-repeat 0 50%;
      -webkit-background-size: 30px 30px;
      -moz-background-size: 30px 30px;
      -o-background-size: 30px 30px;
      background-size: 30px 30px;
      padding-left: 40px;
      height: 30px;
      line-height: 1.9;
    }
$endif$

将结果文件另存为您的pandoc主页中的default.ioslides:

Save the resulting file as default.ioslides in your pandoc home:

$HOME/.pandoc/templates (unix)
C:\Documents And Settings\USERNAME\Application Data\pandoc\templates (windows XP)
C:\Users\USERNAME\AppData\Roaming\pandoc\templates (windows 7)

在Yaml前件中链接的logo现在应该仅显示在标题幻灯片上.

The logo linked in your yaml front matter should now only appear on the title slide.
