如何从Rmarkdown中的.tex文件夹(相对路径)获取图像?

问题描述

我正在尝试获取像这样的水印图像:

I'm trying to get a watermark image like here:

如何在rmarkdown上添加水印图像?

我几乎做到了，但是正如我在最初的问题上所写的那样，\includegraphics获取的background.png图片来自C:\Program Files (x86)\MiKTeX 2.9\tex\plain\present

I almost did it, but as I wrote on my original question the background.png image that the \includegraphics get comes from C:\Program Files (x86)\MiKTeX 2.9\tex\plain\present

我目前正在使用外部文件中的Latex代码，其后缀为.Rmd:

I'm currently using my Latex code from an external file using the follwing at beginning of my .Rmd:

output:
  pdf_document:
    includes:
      in_header: header.tex

在header.tex中，我使用以下代码:

And in header.tex I'm using the following code:

\usepackage{eso-pic,graphicx,transparent}
\AddToShipoutPictureFG{
\put(0,0){%
\parbox[b][\paperheight]{\paperwidth}{%
\centering
  {\transparent{0.3} \includegraphics[width=\paperwidth,height=\paperheight,%
keepaspectratio]{background.png}}%
    }
  }
}

但是我只是无法从我的.tex文件所在的位置获取background.png(与我的.Rmd文件所在的位置相同).

But I just can't get the background.png from where my .tex file is (that is the same that my .Rmd file is).

我如何告诉我的.tex文件从我的.tex的相对路径获取此图像?

How I tell to my .tex file get this image from the relative path to my .tex?

-编辑-我正在使用rmarkdown中的render函数制作报告，以下是我的文件夹中带有.Rmd，.tex文件和尝试插入test.png时出现的错误的屏幕截图:

--EDIT--I'm using the render function from rmarkdown to make the report, follow is a screenshot from the insides of my folder with .Rmd, the .tex file and the error when I try to insert a test.png:

推荐答案

我刚刚做到了.

问题出在Windows的MiKTeX上.

The problem were on MiKTeX for Windows.

我只是按照此答案上的步骤操作，记得要确保该文件夹符合TDS要求(tex文件夹中)，然后将图像放在tex文件夹中.

I just followed the steps on this answer, remembering to assure that the folder is TDS-compliant (with a tex folder in it), and after I just put the image on the tex folder.
