Beamer Poster Gemini：如何在每侧添加多个徽标

2024-5-26 • tag-icon

我正在使用双子座投影机海报\logoright模板。当前功能仅允许使用和在顶部左侧和右侧各添加一个徽标\logoleft。但是，我需要添加 6 个徽标；所以理想情况下每侧 3 个徽标。在每一侧，我想添加三个徽标，这样第一行有两个徽标，第二行将有第三个徽标居中。我该如何定义这样的命令？

您可以在中放置多张图片\logoleft/right。这里有一个包含三张图片的示例\logoright，我相信您可以\logoleft自己调整一下。

% !TeX TS-program = lualatex
\documentclass[final]{beamer}

\usepackage[size=a2]{beamerposter}
\usetheme{gemini}

\logoright{%
  \parbox{13cm}{%
    \centering
    \includegraphics[width=.4\textwidth]{example-image-duck}%
    \hfill
    \includegraphics[width=.4\textwidth]{example-image-duck}%
    \par
    \includegraphics[width=.4\textwidth]{example-image-duck}%
  }
}
