可破坏的 tcolorbox,具有空/隐藏的内部和非空的框架

可破坏的 tcolorbox,具有空/隐藏的内部和非空的框架

我想定义一个可破坏的 tcolorbox,其内部不包含任何颜色或其他绘图代码,因此显示其背后的任何颜色。tcolorboxskins库具有选项interior empty和,interior hidden它们控制内部的绘制,尽管我很难理解这些键和相应的frame empty和之间的相互作用frame hidden。我希望前一个键能够打印围绕盒子内容的框架,而不对内部进行任何处理,但盒子却打印了深灰色背景。

这个答案frame empty,我发现我们可以通过同时设置两者然后interior empty用绘制框架来解决这个问题borderline。这适用于未损坏的框,但如果框损坏,则似乎和frame emptyinterior empty会被忽略,并且 tcolorbox 默认值会生效。

\documentclass{article}

\usepackage[skins,breakable]{tcolorbox}
\usepackage{kantlipsum}

\pagecolor{yellow!10}

\tcbset{enhanced}

\begin{document}

\begin{tcolorbox}[
  interior empty
  ]
This is a \textbf{tcolorbox}.
\end{tcolorbox}

\begin{tcolorbox}[
  interior empty,
  frame empty % don't want hidden frame
  ]
This is a \textbf{tcolorbox}.
\end{tcolorbox}

\begin{tcolorbox}[
  interior hidden
  ]
This is a \textbf{tcolorbox}.
\end{tcolorbox}

\begin{tcolorbox}[
  interior hidden,
  frame hidden, % don't want hidden frame
  ]
This is a \textbf{tcolorbox}.
\end{tcolorbox}

\begin{tcolorbox}[
  frame empty,
  interior empty,
  borderline={1pt}{0pt}{},
]
This is a \textbf{tcolorbox}.
\end{tcolorbox}

\begin{tcolorbox}[
  breakable,
  frame empty,
  interior empty,
  borderline={1pt}{0pt}{},
]
This is a \textbf{tcolorbox}.

盒子

我可能误解了“框架”和“内部”的真正含义,但是有没有办法制作一个内部为空的可破坏的 tcolorbox 呢?

编辑

正如 samcarter_is_at_topanswers.xyz 在评论中指出的那样,“框架”是框后面的一个填充矩形,而不是在其周围绘制的线。这解释了 和 的interior empty输出interior hidden

我还发现,总体而言,breakable与以下交互不太好:frame emptyinterior empty

\begin{tcolorbox}[
  breakable,
  interior empty,
  frame empty
  ]
This is a \textbf{tcolorbox}.
\kant[1-5]
\end{tcolorbox}

当损坏时,这将重置框架和内部默认值。

就上下文而言,我正在尝试适应这个答案用于模拟thmbox使用 tcolorbox 来使用页面背景颜色,而不是预设的背景颜色white,因为这是 thmbox 的行为。

答案1

事实证明答案是阅读文档:)

通常,框架引擎会用颜色填充整个盒子区域,而其他引擎会用其他颜色填充某些区域。[...] 对于某些盒子,需要更精细的程序。例如,如果盒子应该是半透明的,已经涂漆的区域就不能不涂漆。因此,更精致的框架引擎会在框架上打孔,以便内部区域和可选的标题区域进行涂漆。由此产生的皮肤被称为拼图皮肤。

因此只需要使用拼图盒:

\documentclass{article}
\usepackage{xcolor}
\usepackage{pagecolor}
\pagecolor{yellow}
\usepackage[most]{tcolorbox}
\usepackage{kantlipsum}

\begin{document}

\begin{tcolorbox}[
  enhanced jigsaw,
  breakable,
  opacityback=0,
]
This is a \textbf{tcolorbox}.
\kant[1-5]
\end{tcolorbox}

\end{document}

答案2

实际上,你可以让它透明,而不是让 tcolorbox将其涂成与页面相同的颜色,使其透明:

\documentclass{article}
\usepackage{xcolor}
\usepackage[skins,breakable]{tcolorbox}
\usepackage{kantlipsum}
\usepackage{pagecolor}

\pagecolor{yellow}

\tcbset{enhanced}

\begin{document}

\begin{tcolorbox}[
  breakable,
  colback=\thepagecolor
]
This is a \textbf{tcolorbox}.
\kant[1-5]
\end{tcolorbox}


\end{document}

答案3

虽然frame emptyinterior empty在给定时不会按预期工作breakable,但如果给定extras密钥,它们就会起作用。这样我们就可以用伪造框架borderline

\documentclass{article}

\usepackage[skins,breakable]{tcolorbox}
\usepackage{kantlipsum}

\pagecolor{yellow!10}

\begin{document}

\begin{tcolorbox}[
  breakable,
  extras={frame empty,interior empty},
  borderline={1pt}{0pt}{}
  ]
This is a \textbf{tcolorbox}.
\kant[1-5]
\end{tcolorbox}

\end{document}

易碎盒子

答案4

就上下文而言,我正在尝试适应这个答案用于模拟thmbox使用 tcolorbox 来使用页面背景颜色,而不是预设的背景颜色white,因为这是 thmbox 的行为。

看来你需要

\tcbset{
    thmbox/.style={
        % ...
        % colback=white,
        % colframe=white,
        % colbacktitle=white,
        %% in order to imitate effect of "enhanced jigsaw, boxrule=0pt"
        frame engine=empty,
        interior titled engine=empty,
        interior engine=empty,
        extras broken={
          frame engine=empty,
          interior titled engine=empty,
          interior engine=empty
        },
        % ...
    }
}
