使用另一个 tikzpicture 时 backgroundsetup 不起作用

Question

我有一个带有背景设置的文档。当我在页面上使用另一个 tikzpicture（例如坐标系）时，背景图片会放置在错误的位置（见图）。它应该在右上角。有人能提示如何修复它吗？

\documentclass[12pt]{article}
....
\backgroundsetup{
scale=1,
angle=0,
opacity=1,
color=black,
contents={\begin{tikzpicture}[remember picture, overlay]
   \node at ([xshift=18cm,yshift=-1cm] current page.north west)
        {\includegraphics[width = 7cm]{logo_minerva}}; %<- change the name of image
 \end{tikzpicture}}
}
.....

Answer 1

我想这就是你想要的：

\documentclass[12pt]{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\usepackage{mwe}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% background package setup %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\usepackage{background}
\backgroundsetup{
scale=1,
angle=0,
opacity=1,
color=black,
position=current page.north west,
hshift=18cm,
vshift=-1cm,
contents={\includegraphics[width=2cm]{example-image-a}}
}


% Another method:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Direct setup without background package %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%\AddToHook{shipout/background}{
%\begin{tikzpicture}[remember picture, overlay]
%\node at ([xshift=18cm,yshift=-1cm] current page.north west) {\includegraphics[width=2cm]{example-image-a}}; 
%\end{tikzpicture}
%}
