![修改节点的大小及其不透明度](https://linux22.com/image/401637/%E4%BF%AE%E6%94%B9%E8%8A%82%E7%82%B9%E7%9A%84%E5%A4%A7%E5%B0%8F%E5%8F%8A%E5%85%B6%E4%B8%8D%E9%80%8F%E6%98%8E%E5%BA%A6.png)
我正在使用 Tikz 绘制二分图,但似乎没有使节点变小(您可以在代码中看到我为节点指定了不同的大小)或使它们看起来不透明/2D。如果您查看示例,它们似乎是 3D 的。

答案1
设置inner sep
为零,然后将“顶点的最小大小”定义为所需值。例如:
\documentclass[a4paper]{report}
\usepackage{tkz-berge}
\begin{document}
\begin{tikzpicture}[scale=1.5, transform shape]
\SetVertexNoLabel
\tikzset{VertexStyle/.style = {shape=circle, ball color=black, draw,
opacity=0.8, minimum size=4pt, inner sep=0pt}}
\Vertex[x=0,y=0]{A}
\Vertex[x=2,y=2]{B}
\Vertex[x=3,y=1.5]{C}
\Vertex[x=4,y=0]{D}
\tikzset{VertexStyle/.style = {shape=circle, ball color = white, draw,
minimum size=2pt, inner sep=0pt}}
\Vertex[x=0,y=0]{A} % it override first definition of node A
\Vertex[x=0,y=2]{E}
\Vertex[x=2,y=0]{G}
\Vertex[x=3,y=0.5]{H}
\Vertex[x=4,y=2]{I}
\tikzstyle{EdgeStyle}=[]
\Edge(A)(G)
\Edge(A)(E)
\Edge(B)(E)
\Edge(B)(G)
\Edge(B)(I)
\Edge(C)(I)
\Edge(C)(H)
\Edge(D)(H)
\Edge(D)(G)
\Edge(D)(I)
\tikzstyle{EdgeStyle}=[bend right]
\Edge(A)(E)
\Edge(C)(H)
\end{tikzpicture}
\end{document}
关于opacity
您想要获得什么,我不清楚。如果您希望有一些透明度,那么您需要将其设置opacity
为小于 1(在 MWE 中我将其设置为opacity=0.8
)。
答案2
如果您设置,scale=0.5,opacity=0.5
您将获得原始大小一半且透明度为 50% 的节点。
