在rmarkdown的標題頁添加圖像pdf

Question

我正在嘗試創建一個rmarkdown文檔。我終於想出了一個辦法來解決這個問題，儘管它花了相當長的一段時間。我希望能夠做的最後一件事是將圖像添加到我的PDF文檔的標題頁面。

我遇到的麻煩是我的標題頁面是由YAML的頂部部分定義的。以下是我的example.Rmd文件的內容。我使用RStudio中的Knit PDF按鈕將其變成PDF。

title: "This is a my document" 
author: "Prepared by: Dan Wilson" 
date: '`r paste("Date:",Sys.Date())`' 
mainfont: Roboto Light 
fontsize: 12pt 
documentclass: report 
output: 
    pdf_document: 
    latex_engine: xelatex 
    highlight: tango

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see <http://rmarkdown.rstudio.com>. 

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this: 

```{r} 
summary(cars) 
``` 

You can also embed plots, for example: 

```{r, echo=FALSE} 
plot(cars) 
``` 

Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot. 

如果任何人有一些提示，可以讓我把圖片（logo.png）放在我的標題上面，那會很棒。

凡header.tex應包括以下代碼：

\usepackage{titling} 

\pretitle{% 
    \begin{center} 
    \LARGE 
    \includegraphics[width=4cm,height=6cm]{logo.png}\\[\bigskipamount] 
} 
\posttitle{\end{center}} 

，並與你想的圖像替換logo.png使用並確保該文件位於Rmd文件的根目錄中。您可以根據需要更改圖像的寬度和高度。有關可用選項的更多信息，請參閱titling

Answer 2

基於上述解決方案，以下代碼不需要輔助header.tex文件。所有內容均包含在.Rmd文件中。 LaTeX命令是在YAML標題中的header-includes塊中定義的。更多信息可以發現here。

用你的本地圖形文件替換下面的my_graphic.png。

--- 
title: "A title page image should be above me" 
header-includes: 
- \usepackage{titling} 
- \pretitle{\begin{center}\LARGE\includegraphics[width=12cm]{my_graphic.png}\\[\bigskipamount]} 
- \posttitle{\end{center}} 
output: 
    pdf_document: 
    toc: true

\newpage 

# Section 1 

Some text.

對於投影儀演示，你可以做這樣的：

title: "Title" 
subtitle: "Subtitle" 
author: "author" 
date: "date" 
header-includes: 
- \titlegraphic{\centering \includegraphics[width=12cm]{/titlepic.png}} 
output: 
    beamer_presentation: 
    latex_engine: xelatex 
    theme: "metropolis" 
    highlight: "espresso" 
classoption: "aspectratio=169" 

的titlegraphic將被置於下方的標題文字
