增加考试类别的页眉宽度

Question

我需要使用 exam 类将一些文本插入页眉和页脚的边距中。我找到的所有解决方案都使用 fancyhdr 包，但它冲突与考试类中定义的\lhead。\rhead

本质上我想复制 \fancyhfoffset[R]{0.4in}但使用考试类。我尝试在 .sty 中查找 fancyhdr，但它远远超出了我的理解范围...

编辑：很抱歉，我以为没有 MWE 我的问题就足够清楚了。

我想将此页脚（和页眉）向右移动 0.4 英寸（如右箭头所示）。MWE 如下：

\documentclass[12pt]{exam}
\usepackage{amsmath}
\usepackage[a4paper]{geometry}
\geometry{verbose,tmargin=1in,bmargin=1in,lmargin=0.8in,rmargin=1.2in}
\setlength{\parskip}{\smallskipamount}
\setlength{\parindent}{0pt}
\usepackage{mathtools}
\usepackage{graphicx}
\usepackage{lipsum}

\geometry{showframe}   
\addpoints
  
\runningfooter%
    {}
    {}
    {\iflastpage{}{
        \textbf{Question \thequestion }%
        \ifcontinuation{ -- continued}{}\\%
        \oddeven{\textbf{TURN OVER}}{}
        }
    }
%MOVE THIS FOOTER TO THE RIGHT BY 0.4in, same for the header, but I've left it out as the header is even longer which lots of if conditions.

\pagestyle{headandfoot}

\begin{document}
    \begin{questions}
    \question \lipsum[1]
        \begin{parts}
        \part[1] \lipsum[2]
        \newpage
        \part[1] \lipsum[3]
        \newpage
        \part[1] \lipsum[4]
        \newpage
        \part[1] \lipsum[5]
        \end{parts}
    \end{questions}
\end{document}

Answer 1

解决方案是修补页脚和页眉的命令。你可以尝试

\usepackage{xpatch}

\makeatletter
\patchcmd{\run@fullfoot}{\hbox to \textwidth}{\hbox to \dimexpr\textwidth+0.4in\relax}%
{}{\errmessage{Patching of \noexpand\run@fullfoot failed}}
\makeatother

对于标题来说\run@fullhead

Answer 2

不确定是否只有‘TURN OVER’才需要被推入边缘，但这里有一个解决方案：

\documentclass[12pt]{exam}
\usepackage{amsmath}
\usepackage[a4paper]{geometry}
\geometry{verbose,tmargin=1in,bmargin=1in,lmargin=0.8in,rmargin=1.2in}
\setlength{\parskip}{\smallskipamount}
\setlength{\parindent}{0pt}
\usepackage{mathtools}
\usepackage{graphicx}
\usepackage{lipsum}

\geometry{showframe}
\addpoints

\runningfooter%
    {}
    {}
    {\iflastpage{}{
        \textbf{Question \thequestion }%
        \ifcontinuation{ -- continued}{}\\%
        \oddeven{\mbox{\rlap{\makebox[0.46in][r]{\textbf{TURN OVER}}}}}{}
        }
    }
%MOVE THIS FOOTER TO THE RIGHT BY 0.4in, same for the header, but I've left it out as the header is even longer which lots of if conditions.
