'一堆纸' 寻找 mdframed

Question

我试图让mdframed环境看起来像一堆乱糟糟的纸。

我已经想出了如何使用 tikzpreactions来获得我想要的那种外观（见下面的代码）。

我希望通过将 a 传递给 来获得相同的外观tikzsetting，mdframed但它似乎什么也没做。我做错了什么？

\documentclass{article}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw
[preaction={draw=black, fill=white, transform canvas={rotate=1, xshift=2mm, yshift=-2mm}}]
[preaction={draw=black, fill=white, transform canvas={rotate=-1, xshift=.5mm, yshift=-1mm}}]
[fill=white](0,0) rectangle (2,3);
\end{tikzpicture}   

\begin{mdframed}[tikzsetting={preaction={draw=black, fill=white, transform canvas={rotate=1, xshift=2mm, yshift=-2mm}},
                              preaction={draw=black, fill=white, transform canvas={rotate=-1, xshift=.5mm, yshift=-1mm}},
                              draw=black, fill=white}]
    \lipsum[1]
\end{mdframed}
\end{document}

Answer 1

不是一个mdframed，而是一个tcolorbox解决方案，通过应用一个frame code pre密钥：

\documentclass{article}
\usepackage{lipsum}

\usepackage[most]{tcolorbox}
\begin{document}

\begin{tcolorbox}[colback=white,enhanced,sharp corners,
  frame code pre={%
      \draw[fill=white,transform canvas={rotate=1,xshift=-2mm,yshift=-2mm}] (frame.north west) rectangle (frame.south east);
      \draw[fill=white,transform canvas={rotate=-1,xshift=2mm,yshift=2mm}] (frame.north west) rectangle (frame.south east);
    }]
    \lipsum[1]
\end{tcolorbox}

更新

\documentclass{article}
\usepackage{blindtext}
\usepackage[most]{tcolorbox}

\makeatletter
\newtcolorbox{pileofpaper}[1][]{%
  colframe=black,
  colback=white,
  enhanced,sharp corners,
  boxrule=0.5pt,
  frame code pre={%
    \foreach \al/ \x / \y in {1/-1mm/-2mm,-1/-2mm/3mm,-2/2mm/-1mm,3/-2mm/-2mm} {
      \draw[draw=tcbcol@frame,line width=0.2*\kvtcb@left@rule,
      fill=tcbcol@back,
      transform canvas={rotate=\al,xshift=\x,yshift=\y}
      ] (frame.north west) rectangle (frame.south east);
    }
  },
  #1
}
\makeatother

\begin{document}
\begin{pileofpaper}[colback=white!95!gray,colframe=blue]
  \blindtext
\end{pileofpaper}
\end{document}
