平均能量损失

Question

我想创建一个如下页面（尽可能完美）。文本水平居中。

我的尝试产生了以下结果。我不知道字体、背景图案等。但是，背景图案并不那么重要，所以纯色就很好了。

平均能量损失

\documentclass[12pt,demo]{beamer}
\usetheme{rochester}
\setbeamertemplate{headline}{}
\beamertemplatenavigationsymbolsempty
\usepackage{graphicx}

\begin{document}
\begin{frame}[t]{}
\begin{columns}[t]
    \begin{column}{.33\linewidth}
    \begin{center}
        \includegraphics[width=\linewidth,page=2]{croppingwithnavigation}
    \end{center}
    \end{column}
    \begin{column}{.33\linewidth}
    \begin{center}
        \includegraphics[width=\linewidth,page=3]{croppingwithnavigation}
    \end{center}
    \end{column}
    \begin{column}{.33\linewidth}
    \begin{center}
        \includegraphics[width=\linewidth,page=4]{croppingwithnavigation}
    \end{center}
    \end{column}
\end{columns}
Media Marketing\\
Contract package
\end{frame}
\end{document}

问题

如何达到想要的结果？

重要部分按以下顺序排列优先顺序。

• 布局和尺寸（大小）
• 字体
• 背景图案等

您的大多数问题都是针对特定观点的。所以我将布局、颜色、图案等问题留给您回答。

\documentclass[12pt,demo]{beamer}
\usetheme{rochester}
\setbeamertemplate{headline}{}
\beamertemplatenavigationsymbolsempty
%\usepackage{graphicx} it is loaded by bemaer
\usepackage{tabularx}

\begin{document}
\frame{
\setbeamercolor{father}{fg=red}
\setbeamercolor{mother}{bg=green}
\setbeamercolor{child}{parent={father,mother}}
\begin{beamercolorbox}{child}
Terrible red on green text.
\end{beamercolorbox}
\setbeamercolor{father}{fg=blue}
\begin{beamercolorbox}{child}
Now terrible blue on green text, since parent was changed.
\end{beamercolorbox}
}

\begin{frame}
\setbeamercolor{slidebackground}{bg=blue!30}
\setbeamercolor{titlebackground}{bg=gray!30!yellow!20, fg=gray}

    \begin{beamercolorbox}{slidebackground}
\setlength\tabcolsep{3pt}
\begin{center}
\begin{tabularx}{\dimexpr\linewidth-2ex\relax}{XXX}
        \includegraphics[width=\linewidth,page=2]{croppingwithnavigation}
&       \includegraphics[width=\linewidth,page=3]{croppingwithnavigation}
&       \includegraphics[width=\linewidth,page=4]{croppingwithnavigation}
\end{tabularx}\\[1em]

\mbox{}\begin{beamercolorbox}[wd=\dimexpr\linewidth-2ex-6pt\relax,center]{titlebackground}

        \medskip\Large\bfseries
Media Marketing\\[1ex]
    \normalsize\normalfont
\emph{Contract package}\\[1em]
        \end{beamercolorbox}
\end{center}
    \end{beamercolorbox}
\end{frame}
\end{document}

附录： 如果整个框架都是彩色的，则应该background canas为该框架重新定义：

\documentclass[12pt,demo]{beamer}
\usetheme{rochester}
\setbeamertemplate{headline}{}
\beamertemplatenavigationsymbolsempty
\usepackage{tabularx}

\begin{document}

\setbeamercolor{background canvas}{bg=blue!30}
\begin{frame}
\setbeamercolor{titlebackground}{bg=gray!30!yellow!20, fg=gray}
\setlength\tabcolsep{3pt}
\begin{center}
\begin{tabularx}{\dimexpr\linewidth-2ex\relax}{XXX}
        \includegraphics[width=\linewidth,page=2]{croppingwithnavigation}
&       \includegraphics[width=\linewidth,page=3]{croppingwithnavigation}
&       \includegraphics[width=\linewidth,page=4]{croppingwithnavigation}
\end{tabularx}\\[1em]

\mbox{}\begin{beamercolorbox}[wd=\dimexpr\linewidth-2ex-6pt\relax,center]{titlebackground}

        \medskip\Large\bfseries
Media Marketing\\[1ex]
    \normalsize\normalfont
\emph{Contract package}\\[1em]
        \end{beamercolorbox}
\end{center}
\end{frame}
\setbeamercolor{background canvas}{bg=}
\end{document}
