在 Beamer 海报中适合 Tikz 图像

我试图将 tikz 图像放入海报中，但没有成功。图像本身是正确的，但当我尝试将文件导入海报时，写入

 \begin{figure}[htbp]
  %\resizebox{\columnwidth}{!}{
    \input{./Architecture.tex}%}
    \caption{Architecture of the NCS \label{fig:NCS_Architecture}}
 \end{figure}

输出如下：

在此处输入图片描述

缩放方面可能存在问题吗？如果有人能帮助我，我将非常高兴！

谢谢

我的图像代码：

\tikzstyle{block} = [draw, fill=blue!20, rectangle, minimum height=3em, minimum width=6em]
\tikzstyle{sum} = [draw, fill=blue!20, circle, node distance=1cm]
\tikzstyle{input} = [coordinate]
\tikzstyle{output} = [coordinate]
\tikzstyle{pinstyle} = [pin edge={to-,thin,black}]


\begin{tikzpicture}[auto, node distance=2cm,>=latex']

\node [input, name=input] {};
\node [sum, right of=input] (sum) {};
\node [block, right of=sum] (controller) {Controller};
\node [block, right of=controller, pin={[pinstyle]above:Disturbances},node distance=3cm] (system) {System};

\draw [->] (controller) -- node[name=u] {$u$} (system);
\node [output, right of=system] (output) {};
\node [block, below of=u] (measurements) {Measurements};

\draw [draw,->] (input) -- node {$r$} (sum);
\draw [->] (sum) -- node {$e$} (controller);
\draw [->] (system) -- node [name=y] {$y$}(output);
\draw [->] (y) |- (measurements);
\draw [->] (measurements) -| node[pos=0.99] {$-$} node [near end] {$y_m$} (sum);
\end{tikzpicture}

答案1

问题是由于在 tikz 图片中使用了cmas 单位。由于 beamerposter 使用大字体，因此方框太大，并且2cm中心之间的距离不足以避免重叠。

一种解决方案可以表达节点之间的距离，em其中的维度取决于字体大小。更改代码以用于3em每个原始代码cm：

\documentclass{beamer}
\usepackage[orientation=portrait,size=a0,scale=1.6,debug]{beamerposter}                       

\usepackage{tikz}
\begin{document}
\tikzstyle{block} = [draw, fill=blue!20, rectangle, 
minimum height=3em, minimum width=6em]
\tikzstyle{sum} = [draw, fill=blue!20, circle, node distance=3em]
\tikzstyle{input} = [coordinate]
\tikzstyle{output} = [coordinate]
\tikzstyle{pinstyle} = [pin edge={to-,thin,black}]

% The block diagram code is probably more verbose than necessary
\begin{tikzpicture}[auto, node distance=6em]
% We start by placing the blocks
\node [input, name=input] {};
\node [sum, right of=input] (sum) {};
\node [block, right of=sum] (controller) {Controller};
\node [block, right of=controller, pin={[pinstyle]above:Disturbances},
node distance=9em] (system) {System};
% We draw an edge between the controller and system block to 
% calculate the coordinate u. We need it to place the measurement block. 
\draw [->] (controller) -- node[name=u] {$u$} (system);
\node [output, right of=system] (output) {};
\node [block, below of=u] (measurements) {Measurements};

% Once the nodes are placed, connecting them is easy. 
\draw [draw,->] (input) -- node {$r$} (sum);
\draw [->] (sum) -- node {$e$} (controller);
\draw [->] (system) -- node [name=y] {$y$}(output);
\draw [->] (y) |- (measurements);
\draw [->] (measurements) -| node[pos=0.99] {$-$} 
node [near end] {$y_m$} (sum);
\end{tikzpicture}
\end{document}

结果看起来不错：

第二种可能性是使用 tikz 的positioning库。使用此库，相对定位的语法将从 更改为right of=sum等right=of sum，然后 tikz 会智能地将节点之间的距离视为节点边缘之间的距离，而不是中心之间的距离，从而避免重叠。

使用这种方法（并将距离cm再次恢复为 ，而不是em），代码将是：

\documentclass{beamer}
\usepackage[orientation=portrait,size=a0,scale=1.6,debug]{beamerposter}                       
\usepackage{tikz}
\usetikzlibrary{positioning}
\begin{document}
\tikzstyle{block} = [draw, fill=blue!20, rectangle, 
minimum height=3em, minimum width=6em]
\tikzstyle{sum} = [draw, fill=blue!20, circle, node distance=1cm]
\tikzstyle{input} = [coordinate]
\tikzstyle{output} = [coordinate]
\tikzstyle{pinstyle} = [pin edge={to-,thin,black}]

% The block diagram code is probably more verbose than necessary
\begin{tikzpicture}[auto, node distance=3cm]
% We start by placing the blocks
\node [input, name=input] {};
\node [sum, right=of input] (sum) {};
\node [block, right=of sum] (controller) {Controller};
\node [block, right=of controller, pin={[pinstyle]above:Disturbances},
node distance=3cm] (system) {System};
% We draw an edge between the controller and system block to 
% calculate the coordinate u. We need it to place the measurement block. 
\draw [->] (controller) -- node[name=u] {$u$} (system);
\node [output, right=of system] (output) {};
\node [block, below=of u] (measurements) {Measurements};

% Once the nodes are placed, connecting them is easy. 
\draw [draw,->] (input) -- node {$r$} (sum);
\draw [->] (sum) -- node {$e$} (controller);
\draw [->] (system) -- node [name=y] {$y$}(output);
\draw [->] (y) |- (measurements);
\draw [->] (measurements) -| node[pos=0.99] {$-$} 
node [near end] {$y_m$} (sum);
\end{tikzpicture}
\end{document}
