Question

我在横向模式下包含大图像时遇到问题

这大约是图像渲染的最大尺寸

改变尺寸会导致方向切换

理想情况下，我希望能够在这个横向页面上显示一张大图像，这就是我将页面设计为横向的原因。

另外，重要的是，pdf 中的页面要旋转 90 度（目前就是这种情况），这样当我在屏幕上阅读文档时，就不必倾斜头部来查看横向页面。我希望在任何解决方案中都保留这一点。

以下是示例代码

\documentclass{article}
\usepackage[margin=1.0in]{geometry}

% so that i can crop images
\usepackage{graphicx}
\usepackage{wrapfig}
\usepackage{lscape}
\usepackage{rotating}
\usepackage{epstopdf}
\usepackage{pdflscape}
\usepackage{showframe}
\usepackage[paper=portrait,pagesize]{typearea}


% this is needed for positioning images
\usepackage{float}

    }
\end{figure}
\newpage
\KOMAoptions{paper=portrait,pagesize}

\restoregeometry
\cleardoublepage

\end{document}

当图像停止托管时，其大小如下：

Answer 1

• showframe在文档中，环境中的某些页面landscape无法显示横向页面的正确页面边框
• 在横向页面中您应该使用图像宽度\linewidth因为\textwidth不会改变
• 对于横向方向，请只使用一个包，而不是同时使用两个包：lscape和pdflscape（两者都会在打印的文档中给出相同的结果，但在屏幕上pdflcsape旋转横向页面以更简单地查看其内容）

以下 mwe，其中我省略了所有与您的问题无关的包。

\documentclass{article}

\usepackage[demo]{graphicx}
\usepackage{pdflscape}

\usepackage{showframe}
\usepackage{lipsum}

\begin{document}
\thispagestyle{empty}
\lipsum[1]
\begin{landscape}
\noindent%
XXX \hfill XXX % for show width of text area
\begin{figure}[htb]
\fbox{
     \includegraphics[width=\dimexpr\linewidth-4\fboxsep-2\fboxrule]{test.png}
     }
\end{figure}
\end{landscape}
\lipsum[2]
\end{document}

给出

附录： 现在有了标题和示例图像（您应该使用自己的图像），并删除了以前解决方案中显示文本区域大小的内容。

\documentclass{article}
\usepackage{geometry}% added  nut it not influence on solution

\usepackage{graphicx}
\usepackage{pdflscape}

\usepackage{lipsum}

\begin{document}
\thispagestyle{empty}
\lipsum[1]
\begin{landscape}
    \begin{figure}[htb]
\includegraphics[width=\linewidth]{example-image-duck}% example image provided by "graphicx"
\caption{This is some caption text that I'm using to see what this looks like with caption text. I'm not too sure about adding text in the landscape environment, as I use in my real document ... sorry, i can use image provided by you in \texttt{igmur}.}
\label{fig:landscape}
    \end{figure}
\end{landscape}
\lipsum[2]
\end{document}

如您所见，图像位于文本区域的中心。由于现在fbox被删除，图像的宽度仅由以下因素决定：\linewidth

Answer 2

只要使用就landscape可以了（我做了我自己的图像版本，哈哈）。

该解决方案可确保在打印时/如果打印，页面将照常打印，阅读者必须倾斜书本，但在数字形式下，生成的 pdf 是带有倾斜页面的。
