背景图像的圆角

Question

以下是我的 MWE这里：

\documentclass[varwidth]{standalone}
\usepackage{ eso-pic,tikz, lipsum}
\usetikzlibrary{tikzmark}
\linespread{2}
\newcommand\BackgroundPic{%
\begin{tikzpicture}[overlay,remember picture]
\node[anchor=north west,inner sep=0pt, rounded corners=10pt] at ([yshift=8pt]pic cs:start) {%
\includegraphics[width=\textwidth]{example-image}};
\end{tikzpicture}}

\begin{document}
\AddToShipoutPicture*{\BackgroundPic}

\tikzmark{start}\lipsum[1-1]\tikzmark{end}

\end{document}

我希望背景图像有圆角。但是它不行。

如何获得带圆角的背景图像？

Answer 1

另一个解决方案是tcolorbox。由于blankest选项抑制圆角，其效果已使用boxsep=0t和其他几何参数进行了模拟。

\documentclass[tikz, border=2mm]{standalone}
\usepackage{graphicx, lipsum}
\usepackage[most]{tcolorbox}

\newtcolorbox{myminipage}[3][]{
     enhanced,
%    blankest, 
%    rounded corners,
     boxsep=0pt,
     left=0pt,
     right=0pt,
     top=0pt,
     bottom=0pt,
    width=#2,
    underlay={\begin{tcbclipframe}
    \node at (frame) {\includegraphics{#3}};
    \end{tcbclipframe}},
    #1
}

\begin{document}

\begin{myminipage}{3cm}{example-image}
This is some text not so long like \texttt{\textbackslash{}lipsum[2]}
\end{myminipage}

\begin{myminipage}{10cm}{example-image}
\lipsum[2]
\end{myminipage}
\end{document}

Answer 2

clip一起使用rounded corners，同时包含图像。

\documentclass[varwidth,border=10pt]{standalone}
\usepackage{calc}
\usepackage{ eso-pic,tikz, lipsum}
\usetikzlibrary{tikzmark}
\linespread{2}
\newcommand\BackgroundPic{%
\begin{tikzpicture}[overlay,remember picture]
\node[anchor=north west,inner sep=0pt, clip, rounded corners=20pt] at ([yshift=15pt,xshift=-5pt]pic cs:start) {%
\includegraphics[width=\textwidth+10pt]{example-image}};
\end{tikzpicture}}

\begin{document}
\AddToShipoutPicture*{\BackgroundPic}   
\tikzmark{start}\lipsum[1-1]\tikzmark{end}   
\end{document}
