LaTeX/TikZ 森林节点后面的背景图像

Question 1

以下是 SandyG 答案的改编，不需要标签：

\documentclass{article}
\usepackage{forest}

\forestset{scroll/.style 2 args={
    content={\includegraphics[width=4cm]{5FHPu.png}},
    tikz={\node[align=center,yshift=-2.5mm] at () {#1\\*\ #2};},
    edge path={\noexpand\path[\forestoption{edge}] ([yshift=-3mm]!u.parent anchor)--(.child anchor)\forestoption{edge label};}
}}

\begin{document}
\begin{forest}
for tree={
    child anchor=south,
    parent anchor=north,
    grow'=north,
}
[, scroll={Child}{1722}
    [, scroll={Father}{1702}]
    [, scroll={Mother}{1701}]
]
\end{forest}
\end{document}

Question 2

您可以使用放置滚动图像content=，并将文本放置为label。我建议保持所有滚动尺寸相同。

\documentclass{article}
\usepackage{forest}

\forestset{scroll/.style={
    content={\includegraphics[width=2cm]{5FHPu.png}}, 
    label={[label distance=-6mm]below:#1},
    edge path={\noexpand\path[\forestoption{edge}] ([yshift=-3mm]!u.parent anchor)--(.child anchor)\forestoption{edge label};}
}}

\begin{document}
\begin{forest}
for tree={
    child anchor=south,
    parent anchor=north,
    grow'=north
}
[, scroll=Child
    [, scroll=Father]
    [, scroll=Mother]
]
\end{forest}
\end{document}

Question 3

以下是Alan Munn 的回答它会自动处理长名称（或日期）。它提供了一种family tree用于序言的样式。节点内容应以以下格式提供

<name or first line>:<date or second line>

然后，代码让 Forest 计算最宽节点并将其与标准宽度进行比较。如果最宽节点太宽而无法适应标准宽度，则对树中的所有滚动进行调整。然而，我们并不希望背景中的图像简单地缩放，因为这会创建不必要的深节点。所以我们只缩放滚动图像的中间部分，并且只在水平方向上缩放。

为了避免代码重复，图像被分成三个修剪和剪切的部分。这些部分被保存到专用框中并缩放。这三个框提供了卷轴的三个部分：一个用于左侧，一个用于中间，一个用于右侧。在“标准”情况下，名称和日期适合这个标准化卷轴的中间，我们只使用这些框。但是，如果内容太宽，则首先拉伸卷轴的中间部分以适应额外的宽度。

结果如下：

这些树的输入是

\begin{forest}
  family tree
  [Child:1722
    [Father:1702]
    [Mother:1701]
  ]
\end{forest}

对于“标准”情况

\begin{forest}
  family tree,
  [Child:1722
    [Father:1702
      [Paternal Grandfather:1680]
      [Paternal Grandmother:1682]
    ]
    [Mother:1701
      [Maternal Grandfather:1680]
      [Maternal Grandmother:1682]
    ]
  ]
\end{forest}

对于‘拉伸’。

由于节点的内容位于水平中心，而滚动图像略微不平衡，因此放置位置并不完美。（右端比左端宽一点。）然而，在实践中，这似乎看起来是正确的（其他答案也这样做了）。如果您想要更多或更少的“标准”情况的余地，您可以更改min scroll wd一棵或所有树。默认值为61pt。例如，

\begin{forest}
  family tree,
  min scroll wd'=30pt
  [Child:1722
    [Father:1702]
    [Mother:1701]
  ]
\end{forest}
\begin{forest}
  family tree,
  min scroll wd'=100pt
  [Child:1722
    [Father:1702]
    [Mother:1701]
  ]
\end{forest}
