通过任意方法生成考试文档类中题目和选项的jpg图片

以下是TeX文件的代码。

 \documentclass{exam}
    \begin{document}
    \begin{questions}
    \question  Sample Question
    \begin{choices}
    \choice choice 1
    \choice choice 2
    \choice choice 3
    \choice choice 4
    \end{choices}
    \end{questions}
    \end{document}

是否可以使用 make4ht 或 htlatex 或 lua 代码或任何其他方法来生成每个问题和每个选项的 jpg 图像（因此上述 tex 文件中的示例问题将生成五张图像：一张用于问题，另一张用于四个选项。）jpg 文件不应包含问题编号和选项标签。最后，图像将命名为1.jpg, 2.jpg, 3.jpg, 4.jpg, 5.jpg问题 1 及其四个选项。第二个问题将有五张图像命名为6.jpg, 7.jpg, 8.jpg, 9.jpg, 10.jpg等等。

尝试这个配置文件：

\Preamble{xhtml}

% this counter will be used for picture numbering
\newcount\choicespic

% configure pictures to be .jpg
\Configure{Picture}{.jpg}

\def\setupnextpicture{%
  \global\advance\choicespic by 1%
  \NextPictureFile{\the\choicespic}%
}

% configure markup and images for the choices environemnt
\ConfigureList{choices}
{\let\origchoice\choice\HCode{</div>}\def\choiceend{}}% 
{\choiceend\let\choice\origchoice}
{%
  \choiceend\HCode{<div class="choice">}%
  \def\choiceend{\HCode{</div>}}% 
  % update image name
}
{
  \setupnextpicture% declare new picture name
  \Picture*{}% start picture
  \def\choice{\EndPicture\origchoice}% close picture before every \choice command
}
% close picture at end of the choices environment
\AtEndEnvironment{choices}{\EndPicture}
% close \question picture
\BeforeBeginEnvironment{choices}{\EndPicture}

\makeatletter
% save original version of questions environemtn
\let\orig@questions\questions
% redefine the \process@question command to start the picture
\def\questions{%
 \orig@questions% execute the original code
 \let\origprocessquestion\process@question % save \process@question
 \def\process@question{\origprocessquestion\setupnextpicture\Picture*{}}%
}
 
\makeatother

\ConfigureList{questions}
{%
 \def\questionlistend{} % reset questionlistend
 \AnchorLabel\SkipRefstepAnchor% remove link inserted by \label
 \Configure{()}{$}{$}% disable pictures for math
}
{\questionlistend}
{%
  \ifvmode\IgnorePar\fi\EndP\questionlistend%
  \HCode{<div class="question"><div class="questiontitle">}%
  \def\questionlistend{\HCode{</div>}%
  \AnchorLabel\SkipRefstepAnchor%
}
}
{}%{\setupnextpicture\Picture*{}}

\AtEndEnvironment{questions}{\HCode{</div>}}


\begin{document}
\EndPreamble

该类的问题exam在于它定义了一些仅在环境内有效的命令，因此修补它们非常困难。

使用编译

make4ht -c config.cfg exam.tex

结果如下：

在此处输入图片描述

和 HTML：

  <div class='questions'>
    <a id='x1-3x1'></a><div class='question'><div class='questiontitle'>
 1. <img alt='Sample Question  ' src='1.jpg' />
            </div><div class='choice'>
         A.  <img alt='choice 1  ' src='2.jpg' />
            </div><div class='choice'>
         B.  <img alt='choice 2  ' src='3.jpg' />
            </div><div class='choice'>
         C.  <img alt='choice 3  ' src='4.jpg' />
            </div><div class='choice'>
         D.  <img alt='choice 4  ' src='5.jpg' /></div>
 2. <img alt='Second Question  ' src='6.jpg' />
            </div><div class='choice'>
            <a id='x1-82'></a>A. <img alt='choice 5  ' src='7.jpg' />
            </div><div class='choice'>
         B.  <img alt='choice 6  ' src='8.jpg' />
            </div><div class='choice'>
         C.  <img alt='choice 7  ' src='9.jpg' />
            </div><div class='choice'>
         D.  <img alt='choice 8  ' src='10.jpg' /></div>
</div>
