如何在标题幻灯片上对齐来自两个不同框的文本？

Question

我正在尝试匹配 PowerPoint 模板，因为，好吧，这里有人喜欢 PowerPoint 吗？将图像替换为公共领域的图像，它看起来像这样：

不，我并没有故意选择我能找到的最不好看的东西。我的代码已经做到了这一点：

使用此徽标

和图像这里作为背景。我的 MWE 是使用这个.tex文件制作的

\documentclass{beamer}
    \usetheme{generic}
    \title{This Is Sort Of A Descriptive Title}
    \author{Author}
    \institute[Inst.]{Institute}
    \date{Date}
\begin{document}
    \begin{frame}[plain]
        \titlepage
    \end{frame}
\end{document}

这个和这个简单的beamerthemegeneric.sty文件：

\RequirePackage{tikz}
\useinnertheme[shadow=true]{generic}
\addtobeamertemplate{title page}{
    \begin{tikzpicture}[remember picture,overlay]
        \node [xshift=0cm,yshift=0cm] at (current page.center) {
            \includegraphics[width=\paperwidth,height=\paperheight]{wikiCommonsPic}
        };
        \node [xshift=0cm,yshift=0cm] at (0.068\paperwidth,0.044\paperheight) {
            \includegraphics[width=0.27\paperwidth]{fakeLogo}
        };
    \end{tikzpicture}
}{}

beamerinnerthemegeneric.sty不过我的问题在于这个文件：

\DeclareOptionBeamer{shadow}[true]{\def\beamer@themerounded@shadow{#1}}
\ExecuteOptionsBeamer{shadow=false}
\ProcessOptionsBeamer
\setbeamercolor{title page}{fg=white}
\setbeamercolor{titlelike}{fg=white}
\defbeamertemplate*{title page}{myCustom}[1][]{
    \vfill
    \hbox{
        \vbox{
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{title}
                \usebeamerfont{title}\inserttitle
                \ifx\insertsubtitle\@empty
                \else
                    \vskip0.25em
                    {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle}
                \fi
            \end{beamercolorbox}
        }
        \vbox{
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{author}
                \usebeamerfont{author}\insertauthor
            \end{beamercolorbox}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{institute}
                    \usebeamerfont{institute}\insertinstitute
            \end{beamercolorbox}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{date}
                    \usebeamerfont{date}\insertdate
            \end{beamercolorbox}
            \ifx\inserttitlegraphic\@empty
            \else
                \vskip0.25em
                {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic}
            \fi
        }
    }
    \vskip0pt
}
\setbeamertemplate{title page}[myCustom][colsep=-4bp,rounded=true,shadow=\beamer@themerounded@shadow]

如何像在 PowerPoint 中一样将标题文本的顶行与作者文本的顶行对齐？我尝试在各个地方插入胶水，但许多尝试甚至无法编译，说我有一个多余的}（这对我来说没有意义）。

Answer 1

使用这个变体（我使用顶部对齐的sbeamerinnerthemegeneric.sty而不是es ）：\vboxminipage

\DeclareOptionBeamer{shadow}[true]{\def\beamer@themerounded@shadow{#1}}
\ExecuteOptionsBeamer{shadow=false}
\ProcessOptionsBeamer
\setbeamercolor{title page}{fg=white}
\setbeamercolor{titlelike}{fg=white}
\defbeamertemplate*{title page}{myCustom}[1][]{
    \vfill
    \hbox{
        \begin{minipage}[t]{0.4\paperwidth}
            \vspace*{0pt}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{title}
                \usebeamerfont{title}\inserttitle
                \ifx\insertsubtitle\@empty
                \else
                    \vskip0.25em
                    {\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle}
                \fi
            \end{beamercolorbox}
        \end{minipage}%
        \begin{minipage}[t]{0.6\paperwidth}
            \vspace*{0pt}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{author}
                \usebeamerfont{author}\insertauthor
            \end{beamercolorbox}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{institute}
                    \usebeamerfont{institute}\insertinstitute
            \end{beamercolorbox}
            \begin{beamercolorbox}[wd=0.4\paperwidth,sep=8pt,left,#1]{date}
                    \usebeamerfont{date}\insertdate
            \end{beamercolorbox}
            \ifx\inserttitlegraphic\@empty
            \else
                \vskip0.25em
                {\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic}
            \fi
        \end{minipage}
    }
    \vskip0pt
}
\setbeamertemplate{title page}[myCustom][colsep=-4bp,rounded=true,shadow=\beamer@themerounded@shadow]
