wrapfig 下方有空格

Question

我习惯wrapfig让文本整齐地围绕在图像周围。我有一块文本，右边有一张图片，然后是填充线，后面跟着更多文本。我无法让第二块文本填满页面宽度。

我尝试了这个问题，这在一定程度上有效，但对填充线下方的第二段文本无效。将图像样式更改为浮动没有任何区别，但添加\vspace{-70pt}到块中wrapfig确实允许第一段文本恢复占据整个页面宽度，但填充线后的文本具有与 相关的空白wrapfig。

这是 MWE：我还尝试使用 adjustwidth 包围行为不当的文本，以强制其填满页面，但它没有响应。可以注释掉 adjustwidth 命令，而不会更改显示的页面。img_fibre.jpeg 是一个 300x145 像素的图像。

Answer 1

您需要将环境放在命令wrapfigure后面section

对于垂直调整，您可以使用 wrapfig 环境的可选参数来更改 wrapbox 的高度作为解决方法。

\documentclass[11pt]{exam}
\RequirePackage{adjustbox}
\usepackage{changepage}
\usepackage{wrapfig2}
\usepackage[margin=0.4in]{geometry}

\parindent 0ex

\begin{document} 
    
    \section*{Applications of Total Internal Reflection}

    \begin{wrapfigure}[6]{R}{0.45\textwidth}
        \vspace*{-\baselineskip}
        \adjustimage{width=0.43\textwidth,height=3cm}{example-image}
    \end{wrapfigure}

Answer 2

这显示了一个 paracol 解决方案。Paracol 比 wrapfig 更强大，尽管它可能需要手动分段。

请注意，考试类别与几何包不兼容，尽管问题可能很微妙。

\documentclass[11pt]{exam}
%\usepackage[margin=0.4in]{geometry}% not compativble with exam class
\RequirePackage{adjustbox}
\usepackage{changepage}
\usepackage{paracol}
\globalcounter*

\parindent 0ex
\extrawidth{1.2in}% how exam class sets margins

\begin{document} 

\begin{paracol}{2}
