如何避免大图像（整页图像）前出现空白页？

如果我插入高度大于 的全页图像\textheight，则图像前会插入一个空白页。我该如何避免这种情况？

查看最小示例：

\documentclass[twocolumn]{scrbook}
\usepackage{epigraph}% needed for \cleartoevenpage
\usepackage{graphicx}% needed for \includegraphics
\usepackage[left=2.2cm,right=2.2cm,bottom=2.6cm,top=3.2cm]{geometry}
% beschnittrand (what is that called in english?)
\usepackage[cam,noinfo,width=9.15278in,height=12.5833in,center]{crop}

\newcommand{\FullPageImg}[2][width=\textwidth]{% insert large image
    \onecolumn% otherwise there will be too much white space on the left side
    \cleartoevenpage% image shall be on the left side
    \thispagestyle{empty}% no page number
    \vspace*{-38mm}% move image to top of page
    \noindent\makebox[\textwidth]{\includegraphics[#1]{#2}}%include image
    \clearpage%continue on next page
    \twocolumn%switch back to twocolumn style
}
\begin{document}
this is a book. 
this page contains some twocolumn text. 
the following page should contain a fullpage image, but it is empty. 
the page after the image contains again some text.
\FullPageImg[width=214mm,height=301mm,draft]{./graphics/somegraphicsfile.png}%
some text on the page after the image
\end{document}

预期：一份 3 页的文档

获取：一份 4 页的文件

如果height设置为30mm而不是301mm，则不会出现空白页。

由于您的设置没有向 LaTeX 提供关于框高度的信息，因此检测到框太高，因此 LaTeX 跳过了一页。以下内容确实告诉 LaTeX 内容的\textheight高度和\textwidth宽度：

\documentclass[twocolumn]{scrbook}
\usepackage{epigraph}% needed for \cleartoevenpage
\usepackage{graphicx}% needed for \includegraphics
\usepackage[left=2.2cm,right=2.2cm,bottom=2.6cm,top=3.2cm]{geometry}
% beschnittrand (what is that called in english?)
\usepackage[cam,noinfo,width=9.15278in,height=12.5833in,center]{crop}

\newcommand{\FullPageImg}[2][width=\textwidth]{% insert large image
    \onecolumn% otherwise there will be too much white space on the left side
    \cleartoevenpage% image shall be on the left side
    \thispagestyle{empty}% no page number
    \vspace*{-38mm}% move image to top of page
    \noindent\vbox to \textheight{%
        \hbox to \textwidth{%
            \hskip0.5\textwidth\makebox[0pt][c]{\includegraphics[#1]{#2}}}}%include image
    \clearpage%continue on next page
    \twocolumn%switch back to twocolumn style
}
\begin{document}
this is a book. 
this page contains some twocolumn text. 
the following page should contain a fullpage image, but it is empty. 
the page after the image contains again some text.
\FullPageImg[width=214mm,height=301mm]{example-image}%
some text on the page after the image
\end{document}
