如何为对象的“复制阴影”添加标签？

我使用以下 MWE，它会产生一个由 4 个方块组成的堆栈，其中最上面的一个方块标有“0”标签。我想要的是将标签“1”、“2”和“3”添加到最上面的方块后面的相应方块上。

\documentclass{report}
\usepackage[english]{babel}

\usepackage{tikz}
\usetikzlibrary{shadows}

\begin{document}
\begin{tikzpicture} 
  \node[
    minimum width = 3cm,
    minimum height = 3cm,
    draw, fill = white,
    copy shadow = {shadow xshift = 3ex, shadow yshift = -3ex},
    copy shadow = {shadow xshift = 2ex, shadow yshift = -2ex},
    copy shadow = {shadow xshift = 1ex, shadow yshift = -1ex}
  ] (Block) {};

  \node[inner sep = 2pt, below left] at (Block.north east) {0};
\end{tikzpicture}
\end{document}

我会在这里使用循环和标签，这样您就不必手动放置它们。

代码

\documentclass[tikz,convert=false,border=40pt]{standalone}
\usetikzlibrary{shadows}
\tikzset{
  copy shadow label/.style={
    at={(\myCopyshadownode.north east)},
    anchor=north east,
    inner sep=+2pt},
  labeled copy shadow xshift/.initial=1em,
  labeled copy shadow yshift/.initial=-1em,
  labeled copy shadow/.style={
    append after command={
      \pgfextra{\let\myCopyshadownode\tikzlastnode}
      node[copy shadow label/.try] {0}
    },
    @labeled copy shadow/.list={#1,...,1}},
  @labeled copy shadow/.style={
    copy shadow={
      shadow xshift={#1*\pgfkeysvalueof{/tikz/labeled copy shadow xshift}},
      shadow yshift={#1*\pgfkeysvalueof{/tikz/labeled copy shadow yshift}}},
    append after command={
      node[copy shadow label/.try,
           xshift=#1*\pgfkeysvalueof{/tikz/labeled copy shadow xshift},
           yshift=#1*\pgfkeysvalueof{/tikz/labeled copy shadow yshift}] {#1}
    }
  }
}
\begin{document}
\begin{tikzpicture}
  \node [
    minimum size=+3cm, draw, fill=white,
    labeled copy shadow=3] {};
\end{tikzpicture}
\end{document}

在 tikz 之外，它们可以以嵌套方式堆叠。您可以设置水平和垂直移位。

\documentclass{report}
\usepackage[english]{babel}
\usepackage{tikz}
\usepackage{stackengine}
\begin{document}
\def\mypic#1{%
\begin{tikzpicture}
  \node[
    minimum width = 3cm,
    minimum height = 3cm,
    draw, fill = white,
  ] (Block) {};

\node[inner sep = 2pt, below left] at (Block.north east) {#1};
\end{tikzpicture}
\unskip}
\def\hgap{\hspace{1em}}  % YOU CAN ALTER THIS HORIZONTAL SHIFT
\setstackgap{L}{2ex}     % YOU CAN ALTER THIS VERTICAL SHIFT
\def\stackalignment{l}
\def\stacktype{L}
\stackon{\hgap\hgap\hgap\mypic{4}%
}{%
  \stackon{\hgap\hgap\mypic{3}%
  }{%
    \stackon{\hgap\mypic{2}%
   }{%
      \mypic{1}%
   }%
  }%
}%
\end{document}

如果将垂直堆栈间隙设置为负数，则结果（毫不奇怪）将呈现不同的形式：
