如何在Markdown中为PDF文档添加图像作为页眉/页脚

Question

I want to add images as headers and footers (in keeping with my organizations visual identity) to PDF reports. I've managed to do it in Sweave but I'd also like to be able to do it using just Markdown. I can insert the image using ![footer](H:/R/Footer.pdf) however when I try to use the wallpaper package (like I do in Sweave) I get an error.

\LRCornerWallPaper{0.99}{![footer](H:/R/Footer.pdf)} 

Is there a way in Markdown, or do I need to stick to Sweave?

Answer 1

在这种情况下， wallpaper包的正确用法将是简单的

\LRCornerWallPaper{0.99}{path/to/pic}

header-includes:
- \usepackage{fancyhdr}

- \setlength\headheight{45pt}
- \fancyhead{\includegraphics{header.jpg}}
- \setlength\footskip{5pt}
- \fancyfoot{\includegraphics{footer.jpg}}
output: 
  pdf_document:
   fig_caption: false
