修改节点的大小及其不透明度

Question

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。

\documentclass[a4paper]{report}

\usepackage{tikz}
\usetikzlibrary{arrows,%
                petri,%
                topaths}%
\usepackage{tkz-berge}

\begin{document}
\begin{tikzpicture}[scale=1.5]
  \SetVertexNoLabel
\tikzset{VertexStyle/.style ={shape = circle, ball color = black, draw, opacity=1, minimum size = 4pt, fill=black}}
  \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, minimum size = 2pt, draw}}
  \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}

Answer 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）。

Answer 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。

  \Vertex[x=3,y=1.5]{C}
  \Vertex[x=4,y=0]{D}

scale=0.5,opacity=0.5, draw}}
  \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}
