章節標示和附錄

Question

我正在使用bookdocumentclass 建立一個文件。在本文檔中，我使用 @TomBombadil 的答案添加了章節標記如何在章節的每一頁上新增標記？。

奇怪的是，雖然程式碼在章節中運作良好，但在添加附錄時，由於一個奇怪且不清楚的錯誤（至少對我來說），我無法產生文檔

包 PGF 數學錯誤：未知函數“A”（在“-A/20*29.69974”中）。

我的程式碼是

\documentclass[11pt,a4paper]{book}
\usepackage{lipsum}


\let\MakeUppercase\relax
\usepackage{etex}%Makes able the use of many packages
\usepackage[toc,page]{appendix}
% \input{Preamble/tikz}
\usepackage{tikz}
\usepackage{pgf}
\usepackage{background}
\usetikzlibrary{calc}
\usepackage{xifthen}
\usepackage{totcount}
\regtotcounter{chapter}

\backgroundsetup%
{   contents={%
        \begin{tikzpicture}[overlay]
            \pgfmathtruncatemacro{\mytotalchapters}{\totvalue{chapter} > 0 ? \totvalue{chapter} : 20}
            \pgfmathsetmacro{\mypaperheight}{\paperheight/28.453}
            \pgfmathsetmacro{\mytop}{-(\thechapter-1)/\mytotalchapters*\mypaperheight}
            \pgfmathsetmacro{\mybottom}{-\thechapter/\mytotalchapters*\mypaperheight}
            \ifcase\thechapter
                \xdef\mycolor{white}
                \or \xdef\mycolor{red}
                \or \xdef\mycolor{orange}
                \or \xdef\mycolor{yellow}
                \or \xdef\mycolor{green}
                \or \xdef\mycolor{blue}
                \or \xdef\mycolor{violet}
%                 \or \xdef\mycolor{magenta}
%                 \or \xdef\mycolor{cyan}
                \else \xdef\mycolor{black}
            \fi
            \ifthenelse{\isodd{\value{page}}}
            {\fill[\mycolor] ($(current page.north east)+(0,\mytop)$) rectangle ($(current page.north east)+(-0.5,\mybottom)$);}
            {\fill[\mycolor] ($(current page.north west)+(0,\mytop)$) rectangle ($(current page.north west)+(0.5,\mybottom)$);}
        \end{tikzpicture}
    },
    scale=1,
    angle=0
}
\begin{document}
 \chapter{First chapter}
 \lipsum[1]
 \appendix
 \chapter{Appendix Chapter}
 \lipsum[1]
\end{document}

當我刪除\appendix一切工作正常。知道為什麼會發生這種情況以及如何解決它嗎？

Answer 1

該\appendix命令將 設為\value{chapter}並0使其成為\Alph。因此你會得到錯誤。不使用該chapter計數器，而是使用另一個計數器。在這裡，我定義了 acounter並在每章之後使用 加強它\xpatchcmd。

\documentclass[11pt,a4paper]{book}
\usepackage{lipsum}
\usepackage{xpatch}
\makeatletter
\xpatchcmd{\chapter}{\thispagestyle{plain}}
                    {\thispagestyle{plain}\stepcounter{counter}}
                    {}{}
\makeatother
