无法在 beamerposter 中正确设置 tikzpicture 的大小

无法在 beamerposter 中正确设置 tikzpicture 的大小

我尝试将下面提供的 TikZ 图片插入到 beamerposter 文档中。 正常图片

它由以下代码生成(除了“入射光束”中间的箭头,这是一个多余的细节):

\begin{tikzpicture}
    % axes and origin
    \coordinate (O) at (0, 0);
    \draw node[anchor=north east] {$O$};
    \draw [->] (-3,0)--(3,0) node [pos=0.98, below] {$x$};
    \draw [->] (0,-1)--(0,3) node [pos=0.98, left] {$z$};
    % orts
    \draw [thick, ->] (O)--(1,0) node[pos=1, below] {$\vc e_x$};
    \draw [thick, ->] (O)--(0,1) node[pos=1, left] {$\vc e_z$};
    % vector k and its angle chi
    \coordinate (K) at ({2.6*sin(30)},{2.6*cos(30)});
    \draw [thick, ->] (O)--(K) node[pos=1, right] {$\vc k$};
    \draw ([shift=(60:0.5)] O) arc (60:90:0.5) node[pos=0.35, above] {$\chi$};
    % k projections
    \coordinate (Kx) at (K |- O);
    \coordinate (Kz) at (K -| O);
    \draw [thick, ->](O)--(Kx) node[pos=1.15, below] {$\vc k_x$};
    \draw [thick, ->](O)--(Kz) node[pos=1, left] {$\vc k_z$};
    \draw [dashed] (K)--(Kz);
    \draw [dashed] (K)--(Kx);
    % foton beam
    \draw (-3, 2)--(O) node[pos=0.45, above] {$\ \hbar \omega$};
\end{tikzpicture}

\begin{block}...\end{block}当我在 beamerposter 文档中的任何位置(在内,或者在框架内) 插入这段代码时,我得到了这个丑陋的结果(图像跨越了整个海报宽度):在此处输入图片描述

平均能量损失

\documentclass[final, 24pt]{beamer}\usetheme{Frankfurt}\usecolortheme{orchid}\usefonttheme[onlymath]{serif}\mode<presentation>
\usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}
\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage[english, russian]{babel}
\usepackage{tikz}

\newcommand{\vc}[1]{\mathbf {#1}}
\begin{document}
    \begin{frame}{}
        \begin{center}
            \begin{tikzpicture} 
                 % ... picture code given above
            \end{tikzpicture}
        \end{center}
    \end{frame}
\end{document}

我如何才能让它看起来可接受?通过

\scalebox{2.2}{
    \begin{tikzpicture}[scale=3] 
          % picture code
    \end{tikzpicture}
}

产生此输出(也跨越整个纸张宽度) 在此处输入图片描述

然后我可以手动对线宽进行一些调整(\draw[..., line width=0.33ex]例如)以获得合理的输出: 在此处输入图片描述

我想问社区是否有其他方法可以获得所需的结果(也许这是一个众所周知的问题,但我无法直接在 Google 上搜索到它)以及为什么直接从 a4 文档“移植”漂亮的图像代码会产生这样的垃圾?

欢迎使用 TeX-SE!您可以将一些指令附加到every pathevery node样式中。以下是示例。

         shape}]
             % axes and origin
             \coordinate (O) at (0, 0);
             \draw node[anchor=north east] {$O$};
             \draw [->] (-3,0)--(3,0) node [pos=0.98, below] {$x$};

             \draw [->](O)--(Kz) node[pos=1, left] {$\vc k_z$};
             \end{scope}
             \draw [dashed] (K)--(Kz);
             \draw [dashed] (K)--(Kx);
             % foton beam
             \draw (-3, 2)--(O) node[pos=0.45, above] {$\ \hbar \omega$};
         \end{tikzpicture}
        \end{center}
    \end{frame}
\end{document}

在此处输入图片描述

当然,我不知道您最喜欢什么,但您可以根据需要调整比例。

编辑:修复了箭头。因为 TiZ 解析路径,最简单的选项是通过范围设置线宽。
