我是 Tex 的初学者，我有 tex 文件
\documentclass{article}
\addtolength{\jot}{1em}
\begin{document}
\begin{verbatim}
\end{verbatim}
\begin{chestnutStem}
In the following figure, if the spinner is divided into 8 colored sections, what is the probability of it stopping at blue?
\centerline{\includepdf[page=2]{mypdf.pdf}}
\end{chestnutStem}
\chestnutKey{
$ \frac{1}{4} $
}
\begin{chestnutAnswer}
\begin{align*}
\textrm{The probability of the spinner stopping at blue}&=\frac{\textrm{the number of blue sections}}{\textrm{total number of sections}}\\
&=\frac{2}{8}\\
&=\frac{1}{4}.
\end{align*}
\end{chestnutAnswer}

我想在命令中获取 [page] 值选项\includepdf以便在配置文件中使用它
答案1
pdfpages是导致包含失败的软件包之一tex4ht。在这种情况下，必须更改 TeX 源，这是我们尝试避免的tex4ht。helpers4ht 捆绑包提供\altusepackage命令，可用于加载 的替代版本软件包tex4ht。这些替代软件包名为packagename-alt4ht.sty。它们包含文档中使用的宏的定义。 的定义pdfpages只是基本的，它可用于仅包含一个分页的 pdf 文档。
为了支持多页 pdf 文件，我在包中添加了命令pages选项。它不支持原始的所有功能，因为实现它会非常困难，而且我认为它在 HTML 输出中没有意义：\includepdfpdfpages-alt4ht.sty
\ProvidesPackage{pdfpages-alt4ht}
\RequirePackage{graphicx}
\RequirePackage{xkeyval}
\define@key{includepdf}{pages}{\edef\current@pdf@page{\the\numexpr #1-1\relax}}
\newcommand\includepdf[2][]{%
\def\current@pdf@page{0}
\setkeys*{includepdf}{#1}
\filename@parse{#2}
\def\current@png@name{\filename@area\filename@base-\current@[email protected]}
\IfFileExists{\current@png@name}{}{%
\Needs{"convert #2[\current@pdf@page]
\current@png@name"}
}
\includegraphics{\current@png@name}
}
\endinput
它将请求的页面保存在\current@pdf@page宏中，必须将其减 1，因为imagemagick页面从 0 开始计数。png名称构造为，仅当它尚不存在时才调用程序imagename-pagenumber.png。convert
我必须修复 中的一个问题，其中chestnut.cls缺少：{}IfFileExists

以及你的 TeX 文件，因为chestnut没有使用类：
\documentclass{chestnut}
\addtolength{\jot}{1em}
\begin{document}
\begin{verbatim}
\end{verbatim}
\begin{chestnutStem}
In the following figure, if the spinner is divided into 8 colored sections, what is the probability of it stopping at blue?
\centerline{\includepdf[pages=2]{mypdf.pdf}}
\end{chestnutStem}
\chestnutKey{
$ \frac{1}{4} $
}
\begin{chestnutAnswer}
\begin{align*}
\textrm{The probability of the spinner stopping at blue}&=\frac{\textrm{the number of blue sections}}{\textrm{total number of sections}}\\
&=\frac{2}{8}\\
&=\frac{1}{4}.
\end{align*}
\end{chestnutAnswer}
\end{document}
