我有这个小云形状，我想在我的系统图表中使用它。
\usetikzlibrary{shapes}
\begin{tikzpicture}
\node [cloud, draw,cloud puffs=10,cloud puff arc=120, aspect=2, inner ysep=1em] {};
\end{tikzpicture}
它看起来像这样：
但问题是云太对称了。我希望其中一侧“更短”。类似这样（当然，减去箭头、文本和阴影）：
在手册或网上都找不到任何内容。有什么提示吗？
答案1
这不是一个很好的答案，但是我没有足够的时间来做一个新形状，你可以从这个答案中找到很多例子来做一个新形状（蝙蝠侠或其他形状）。
我手动制作了一朵云，并在里面放置了文字。您可以制作一个宏来同时绘制云和放置文字。
您可以使用节点(cloud)放置箭头等。
你可以做什么：
- 新形状：不对称云
- 或者使用宏来绘制云并放置文本

答案2
我在一次大学讲座中需要在一幅图形中使用云形，我想出了这个解决方案：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[magyar]{babel}
\usepackage{tikz}
\usetikzlibrary{positioning, shapes}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\begin{document}
\begin{tikzpicture}[font=\large\sffamily]
\node[cloud, cloud puffs=15.7, cloud ignores aspect, minimum width=5cm, minimum height=2cm, align=center, draw] (cloud) at (0cm, 0cm) {Cloud};
\end{tikzpicture}
\end{document}
关键是使用cloud ignores aspect关键字，并使用minimum width和minimum height关键字控制宽度和高度。为指定一个浮点数可以实现不对称cloud puffs。
虽然不完美，但这是我现在所用的。
答案3
显然，不对称云甚至可以简单地绘制。您想要的云的精确副本是：
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw (-1.6,-0.7) .. controls (-2.3,-1.1)
and (-2.7,0.3) .. (-1.7,0.3) .. controls (-1.6,0.7)
and (-1.2,0.9) .. (-0.8,0.7) .. controls (-0.5,1.5)
and (0.6,1.3) .. (0.7,0.5) .. controls (1.5,0.4)
and (1.2,-1) .. (0.4,-0.6) .. controls (0.2,-1)
and (-0.2,-1) .. (-0.5,-0.7) .. controls (-0.9,-1)
and (-1.3,-1) .. cycle;
\end{tikzpicture}
\end{document}
编辑。
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand{\AsymCloud}[3]{
\begin{scope}[shift={#1},scale=#3]
\draw (-1.6,-0.7) .. controls (-2.3,-1.1)
and (-2.7,0.3) .. (-1.7,0.3)coordinate(asy1) .. controls (-1.6,0.7)

\node at ($(asy1)!0.5!(asy2)$) {#2};
