如何让图像跨越两列而不分页

Question

我正在制作一个包含两列的文档；但是，我希望将第一页用作封面页，标题跨越两列，封面图片也跨两列。我尝试按如下方式操作，使用将floatrow跨度图像居中：

\documentclass[11pt,twocolumn,landscape]{article}
\usepackage{floatrow}

\begin{document}

\twocolumn[
\centerline{\Large\bf Project Title}
\medskip
\centerline{\Large\bf Subheader}
\medskip
\centerline{\today}
\bigskip
]

\begin{figure*}
\includegraphics[width=\textwidth]{figure.jpg}
\label{fig:label}
\end{figure*}

\clearpage %to end the page

%other content
\end{document}

然而，这总是导致环境之前出现分页符figure*——我无法让图像与标题位于同一页！添加[h]或[H]标签似乎不起作用。我应该怎么做才能让图像与上一个文本保持在同一页上？

Answer 1

您可以使用titlepage环境

\documentclass[11pt,twocolumn,landscape]{article}
\usepackage{graphicx}
\usepackage{kantlipsum}

\begin{document}
\begin{titlepage}
\centering
{\Large\bfseries Project Title}

\medskip

{\Large\bfseries Subheader}

\medskip

{\today}

%\bigskip

\vfill
\includegraphics[width=0.5\textwidth]{example-image-a}

\end{titlepage}

\kant
\end{document}

使用\bfseries已\bf弃用的\centerlineTeX，在 LaTeX 中使用。此外，当您没有标题时，\centering也不需要。\label

Answer 2

使用multicols可能比基本的 LaTeX 更有用\twocolumn。当然，图片被更改了，并缩小到在一页上显示所有内容（因此也\clearpage评论了）。其余部分保持不变，但是许多人不喜欢\bfLaTeX 文档。参见，例如使文本加粗/斜体的“正确”方法是什么？。

%\documentclass[11pt,twocolumn,landscape]{article}
\documentclass[11pt,landscape]{article}
%\usepackage{floatrow}
\usepackage{multicol}

\usepackage{graphicx}

\begin{document}

%\twocolumn[
\centerline{\Large\bf Project Title}
\medskip
\centerline{\Large\bf Subheader}
\medskip
\centerline{\today}
\bigskip
%]

\begin{figure*}[h]
%\includegraphics[width=\textwidth]{figure.jpg}
\includegraphics[width=0.7\textwidth]{it}
\label{fig:label}
\end{figure*}

%\clearpage %to end the page  % Commented to show all on one page - PS



%other content
