多列插入图片超出框架

我试图在投影仪框架中并排添加两幅图像，但其中一幅超出了框架范围。

因此，我的其中一张图片是 pmatrix。我为邻接矩阵表示编写了以下代码：

\documentclass{article}

\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{graphicx}


\pagenumbering{gobble}

\begin{document}

\renewcommand\arraystretch{1}

\[\Huge{ 
\begin{pmatrix}
  2 & 1 & 0 & 0 & 1 & 0 \\
  1 & 0 & 1 & 0 & 1 & 0 \\
  0 & 1 & 0 & 1 & 0 & 0 \\
  0 & 0 & 1 & 0 & 1 & 1 \\
  1 & 1 & 0 & 1 & 0 & 0 \\
  0 & 0 & 0 & 1 & 0 & 0
\end{pmatrix}
}
\]

\vspace{15pt}

\huge{Adjacency Matrix (Coordinates are 1-6)}

\end{document}

我从 sharelatex 下载了 pdf 文件。但是当我添加它时，它超出了框架。这是我的 beamer 代码：

\documentclass[12pt]{beamer}
\usetheme{metropolis}

     An adjacency matrix is a square matrix used to represent a finite graph.
    \end{block}
    \vspace{0.5em}
    For a graph with $\mathbold{\abs{V}}$ vertices, an adjacency matrix is a $\mathbold{\abs{V} \times \abs{V}}$ matrix.
    \\\vspace{1em}
    If the edge between vertex $\mathbold{i}$ and vertex $\mathbold{j}$ is denoted by $\mathbold{V_{i,j}}$ then there are two possibilities.

我怎样才能解决这个问题？

答案1

您使用\Huge和\huge生成矩阵 PDF 图像，然后将其包含在内scale = 0.5。为什么不直接pmatrix在幻灯片中输入您的内容呢？

\begin{multicols}{2}
  \only<4>{
    \centering
    \includesvg[scale = 0.3]{Figures/unweightedgraph.svg}

    \[
    \begin{pmatrix}
      2 & 1 & 0 & 0 & 1 & 0 \\
      1 & 0 & 1 & 0 & 1 & 0 \\
      0 & 1 & 0 & 1 & 0 & 0 \\
      0 & 0 & 1 & 0 & 1 & 1 \\
      1 & 1 & 0 & 1 & 0 & 0 \\
      0 & 0 & 0 & 1 & 0 & 0
    \end{pmatrix}
    \]
    Adjacency Matrix (Coordinates are 1-6)
  }
\end{multicols}

答案2

大部分与您的问题无关，但我无法再次展示如何准备这个框架并避免您的问题：

  • 相反，我会使用 svg 图像来绘制自己的图像tikz（显示的图形相对简单，不需要花费很大的精力来编码）

  • 我会编写矩阵而不是插入其图像（我确信，这更简单并且需要的工作更少）

    \documentclass{beamer}
\usetheme{metropolis}
\usecolortheme{spruce}
\usepackage{tikz}
\usetikzlibrary{automata, positioning}

\begin{document}
\begin{frame}[t]
\frametitle{Adjacency Matrix}

\begin{columns}
    \begin{column}{.45\textwidth}\centering
\begin{tikzpicture}[
every node/.style = {circle, draw=blue!70!black, fill=cyan!30},
    node distance = 3mm and 5mm,
            thick
                    ]
\node (s1) {1};
\node (s2) [above left=of s1]   {2};
\node (s3) [above=of s2]        {3};
\node (s4) [right=of s3]        {4};
\node (s5) [above right=of s1]  {5};
\node (s6) [above right=of s4]  {6};
\draw   (s1) to [loop right, looseness=12] (s1)
        (s1) -- (s2) -- (s3) -- (s4) -- (s5) -- (s1)
        (s2) -- (s5)
        (s4) -- (s6);
\end{tikzpicture}
    \end{column}
    \begin{column}{.45\textwidth}
    \[\setlength\arraycolsep{9pt}
    \begin{pmatrix}
      2 & 1 & 0 & 0 & 1 & 0 \\
      1 & 0 & 1 & 0 & 1 & 0 \\
      0 & 1 & 0 & 1 & 0 & 0 \\

答案3

  • 我不会multicols与 beamer 一起使用 - beamer 有自己的柱子机制。

  • 你不需要\usepackage{graphicx}使用 beamer

  • 就我个人而言，我发现仅指定图像的宽度要容易得多，而不必试验寻找合适的缩放因子。

  • 不要多次使用相同的标签

  • 图形在投影机中自动居中，无需\centering
