Question

我想在目录中的标题周围添加彩色框。该框应从页面边缘开始，并在章节名称结束后结束。

我找到了很多解决方案，可以创建一个从章节号到页码的框。但是，我找不到一个符合我需求的。

下面是我想要实现的一个例子：

注意：由于字体集成问题，我正在使用 XeLatex。

如前所述，我需要使用 XeLatex 来支持 unicode。因此，Tikz 不是一个好的解决方案，因为 tikzmark 和 pgfmark 得不到很好的支持（根据为什么 xelatex 在 tikz 图形中呈现的箭头与 lualatex 不同？以及我的无数次尝试）。

我设法使某些部分正常工作：

\documentclass[a4paper,11pt, american]{report}
\usepackage[utf8]{inputenc}
\usepackage{tocloft,tikz}
\usetikzlibrary{calc}

\makeatletter
\newcommand{\gettikzxy}[3]{%
  \tikz@scan@one@point\pgfutil@firstofone#1\relax
  \edef#2{\the\pgf@x}%
  \edef#3{\the\pgf@y}%
}
\makeatother

\newcommand*{\tikzcoordinate}[1]{%
    \tikz[remember picture, overlay] \coordinate (#1);}
\renewcommand{\cftchapfont}{%
    \tikzcoordinate{A}
    \bfseries\Large%
}
\renewcommand{\cftchappagefont}{\bfseries}
\renewcommand{\cftchapleader}{%
    \tikz[remember picture,overlay]{%
    \coordinate (C);%
    \coordinate (B) at (current page.west|- A);
    \gettikzxy{(A)}{\ax}{\ay}
    \gettikzxy{(B)}{\bx}{\by}
    \gettikzxy{(C)}{\cx}{\cy}
    \fill[red,opacity=.2] ([yshift=+1.3333em,xshift=-.3333em]B) rectangle
                                    ([xshift=.3333em,yshift=+-1ex]C |- 0,0);
    \ifx\by\cy
    \else
        \coordinate (D) at (\cx+.3333em,\by+1.3333em);
        \coordinate (E) at (\ax-.8em+\linewidth- \cftchapindent- \cftchapnumwidth,\cy+1em);
        \gettikzxy{(D)}{\dx}{\dy}
        \gettikzxy{(E)}{\ex}{\ey}
        \ifdim\dx<\ex
            \fill[red,opacity=.2] (D) rectangle (E);
        \else
            \fill[white,opacity=1] (D) rectangle (E);
        \fi
    \fi
  }%
  \bfseries\cftdotfill{\cftdotsep}%
}

其结果为：

现在，我的问题是我需要在背景上使用颜色，以便文本可以以白色显示在背景上。有关于如何使用 XeLatex 实现这一点的提示吗？

Answer 1

终于找到了解决方案。使用 tikzmark 的问题不是 XeLatex。但是，必须使用计数器来确保每个标记名称都是唯一的。可能有一个更简单的解决方案，但这个解决方案运行良好。
