如何操作脚注的文本宽度？

Question

我使用自定义边距，这样我就可以在右边距中包含图片，并在页脚中包含参考资料。我希望页脚跨越正文和边距的线宽。

这是我的最小示例：

\documentclass[10pt,letterpaper]{article}
\usepackage[left=36pt,right=233.28pt,top=2cm,bottom=2cm, marginparwidth=66mm]{geometry}
\usepackage{marginnote}
\usepackage{lipsum}  

\begin{document}

\section{A title goes here}

\lipsum[1-2]

\marginnote{\footnotesize An image goes here in the right margin.}

\lipsum[1-2]\footnote{A footnote goes here in the footer and should stretch right across the page to include the right margin.}

\end{document}

我曾在 Google 上搜索过 \footnotewidth，但没有任何结果。

谢谢

\documentclass[10pt,letterpaper]{article}
\usepackage[left=36pt,right=233.28pt,top=2cm,bottom=2cm, marginparwidth=66mm]{geometry}
\usepackage{marginnote}
\usepackage{lipsum}  

\begin{document}

\section{A title goes here}

\lipsum[1-2]

\marginnote{\footnotesize An image goes here in the right margin.}

\lipsum[1-2]\footnote{\hsize=\dimexpr\columnwidth+\marginparsep+\marginparwidth\relax
A footnote goes here in the footer and should stretch right across the page to include the right margin.}

\end{document}

Answer 2

这里，我在每个脚注里都加了一个负数\rightskip。实际值是-\marginparsep-\marginparwidth。

\documentclass[10pt,letterpaper]{article}
\usepackage[left=36pt,right=233.28pt,top=2cm,bottom=2cm, marginparwidth=66mm]{geometry}
\usepackage{marginnote}
\usepackage{lipsum}  
\let\svfootnote\footnote
\def\footnote#1{\svfootnote{\rightskip\dimexpr
  -\marginparsep-\marginparwidth #1}}
\begin{document}

\section{A title goes here}

\lipsum[1-2]

\marginnote{\footnotesize An image goes here in the right margin. Adding
i i i i more to test margination.  An image goes here in the right margin. 
Adding  more to test margination.  An image goes here in the right margin.
Adding more to test margination.  }

\lipsum[1]\footnote{A footnote goes here in the footer and should stretch right across the page to include the right margin.  Adding a bit more
to check the margination.}

\lipsum[2]\footnote{Testing another footnote.}

\end{document}

Answer 3

您可以使用 LaTeX 框来获得更多宽度。请注意，我使用的是\rlap将框的宽度设置为 0 的方法。这只是为了避免出现“框过满”警告。这有点不合时宜，但嘿，这是 LaTeX。

\newcommand{\widefootnote}[1]{%
    \footnote{\rlap{\parbox{\dimexpr\paperwidth-72pt\relax}{#1}}}%
}

现在使用\widefootnote而不是\footnote。或者你可以这样做

\let\oldfootnote\footnote

\renewcommand{\footnote}[1]{%
    \oldfootnote{\rlap{\parbox{\dimexpr\paperwidth-72pt\relax}{#1}}}%
}

\footnote并到处使用。
