我正在尝试使用 Ti 绘制流程图钾Z。
我希望箭头中的文字出现在路径的左侧或右侧，而不是箭头上方。我也尝试使用节点不透明度来解决这个问题，style={fill=white}但没有成功。
我还设法按照我想要的方式定位节点，但我相信还有很多更简单的方法可以做到这一点。我看到了库matrix和分层布局之类的东西，但无法成功实现它。
最后，我希望有一个像我在图片中手动绘制的箭头。我尝试使用控件，但结果并不完全符合我的预期，因为箭头穿过了一些节点。
非常感谢您的支持。

使用beamer文档类应该意味着您的图像在frame环境中...所以我将您的图像采用为标准大小frame。还使用库quotes进行边缘标记：
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows.meta, positioning, quotes}
\begin{document}
\begin{frame}[fragile]

fill=#1, font=\footnotesize, inner ysep=1.5pt},
box/.default = blue!25,
every edge/.style = {draw, semithick,-Stealth},
every edge quotes/.style = {auto=left, align=center, inner sep=2pt,
font=\scriptsize\linespread{0.7}\selectfont}

\node (a1) [box] {Input};
\node (a2) [box=red!25, font=\small,

如果上面的图像仍然太大，您可以通过添加tikzpicture选项来缩小它，例如：scale=0.9, transform shape,
答案2
这是一个起点。我很乐意删除它。我会从中上部的大节点开始，然后绘制与此相关的内容。而且，正如 Joule V 所提到的，人们可以用来midway放置标签。（你正在添加auto但没有给 Ti钾Z 有机会使用它。)
