为海报制作标题

如果有人能帮助我修复以下代码的标题，那将会非常有帮助：

\documentclass[a0,portrait]{a0poster}
\usepackage{tikz}
\usetikzlibrary{shapes,snakes,arrows,shadows,petri,decorations.markings}
\definecolor{pms286}{RGB}{4,52,177}
\tikzstyle{mybox} = [draw=pms286!80, fill=blue!20, very thick,
rectangle, rounded corners=30pt, inner sep=10pt, inner ysep=30pt,color=blue!20]
\def\Title#1{\noindent{\VeryHuge\color{pms286} #1}}


%\begin{document}
\newcommand{\displaytitle}[3]{%
  \begin{tikzpicture}
    \node [mybox] (box){%
      \begin{minipage}{0.93\textwidth}
    \begin{tabular}{lc}
      \multirow {3}{*}{\includegraphics[width=0.125\textwidth]{some logo}}
      & \baselineskip=3\baselineskip\Title{#1}\\\\
      & \Huge\color{pms286!90}{#2} \\\\
      & \LARGE\color{pms286!80}{#3}\\
    \end{tabular}
      \end{minipage}
    };
  \end{tikzpicture}
}

\begin{document}
\centering
\displaytitle{A very very very very very very \\very very very very very very very very very very
long title. }{Author}{University}
\end{document}

注意：缺少徽标图像，因此编译会出错。但这不是这里的问题。

我的问题是，使用此 displaytitle 设置，标题只有一行。如果标题真的很长（两行），则不能换行。`\' 换行符会删除格式（如图所示）。

请帮忙。在此处输入图片描述

您需要定义一个newcolumntype用于文本换行的数组包。这里定义了两种列类型，需要 #1 宽度参数。P是用于文本垂直对齐在顶部的段落列，而C是用于文本垂直对齐在中间的段落列。此外，multirow还需要一个包，但 OP 中未加载该包。

\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}

代码

\documentclass[a0,portrait]{a0poster}
\usepackage{array,tikz,multirow}
\usetikzlibrary{shapes,snakes,arrows,shadows,petri,decorations.markings}

\definecolor{pms286}{RGB}{4,52,177}
\tikzstyle{mybox} = [draw=pms286!80, fill=blue!20, very thick,
rectangle, rounded corners=30pt, inner sep=10pt, inner ysep=30pt,color=blue!20]
\def\Title#1{\noindent{\VeryHuge\color{pms286} #1}}

\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}

%\begin{document}
\newcommand{\displaytitle}[3]{%
  \begin{tikzpicture}
    \node [mybox] (box){%
      \begin{minipage}{0.93\textwidth}
      \begin{tabular}{l C{0.8\textwidth}}
      \multirow {3}{*}{\includegraphics[width=0.125\textwidth]{example-image-a}}
       &\baselineskip=3\baselineskip\Title{#1}\\\\
       &\Huge\color{pms286!90}{#2} \\\\
       &\LARGE\color{pms286!80}{#3}\\
      \end{tabular}
      \end{minipage}
    };
  \end{tikzpicture}
}

\begin{document}
\displaytitle{A very very very very very very very very very very very very very very very very long title}
{Author}
{University}

\end{document}
