bclogo 分页符

Question

我正在使用 Bclogo 包http://www.ctan.org/pkg/bclogo。我用它创建了引理和证明的环境。证明太大，无法放在页面底部，因此它只是插入了一个分页符并将其移动到下一页（见下图）。有没有办法让它从引理下面的页面开始，然后继续到下一页，而不是将所有内容移动到下一页并留下很大的间隙？

我目前在不同的文件中设置了以下命令，并且只需在文档中调用它们即可输入引理和证明。

\newcounter{LemmaBoxCounter}
\newcommand{\lem}[1]{\begin{bclogo}[logo=\bclampe, noborder=true, couleurBarre=Red, couleurBord=Black, couleur=blue!20, arrondi = 0.2, epBarre=0]{Lemma \arabic{LemmaBoxCounter}}
\raggedright #1
\addtocounter{LemmaBoxCounter}{1}
\end{bclogo}}

\newcounter{ProofBoxCounter}
\renewcommand{\proof}[1]{\begin{bclogo}[logo=\bclampe, noborder=true, couleurBarre=Red, couleurBord=Black, couleur=orange!10, arrondi = 0.2, epBarre=3.5]{Proof \arabic{ProofBoxCounter}}
\raggedright #1 \qed
\addtocounter{ProofBoxCounter}{1}
\end{bclogo}}

Answer 1

我接手了 Christian Hupfer 的接力并给出了一个tcolorbox基础解决方案。我尝试模仿原始宏以获得等效的外观。主要区别在于引理和证明现在是可破坏的框。我省略了，\qed因为我不知道那个是用来做什么的。

宏带有可选参数（任何tcolorbox选项）。例如，用于\lem[label=MyLabel]{....}设置参考标签。

\documentclass[paper=a4,12pt]{scrbook}

\usepackage{etoolbox}%
\usepackage{blindtext}%
\usepackage[tikz]{bclogo}%
\usepackage[skins,breakable,xparse]{tcolorbox}%

\DeclareTotalTColorBox[auto counter]{\lem}{ O{} m }
{ enhanced,breakable,
  boxrule=0pt,boxsep=0pt,arc=2mm,toptitle=3mm,top=3mm,left=7mm,right=1mm,pad at break=2mm,
  colframe=blue!20!white,interior hidden,
  coltitle=black,fonttitle=\bfseries\large,title={Lemma~\thetcbcounter},
  overlay unbroken and first={\node at ([xshift=4mm,yshift=-5mm]frame.north west) {\bclampe};},
  #1}
  {\raggedright #2}

\DeclareTotalTColorBox[auto counter]{\proof}{ O{} m }
{ enhanced,breakable,
  boxrule=0pt,boxsep=0pt,arc=2mm,toptitle=3mm,top=3mm,left=7mm,right=1mm,pad at break=2mm,
  colframe=orange!10!white,interior hidden,
  coltitle=black,fonttitle=\bfseries\large,title={Proof~\thetcbcounter},
  overlay unbroken and first={\node[inner sep=0pt] (logo) at ([xshift=4mm,yshift=-5mm]frame.north west) {\bclampe};
    \draw[red,line width=3.5pt] (logo) -- ([xshift=4mm,yshift=1.5mm]frame.south west);  },
  overlay middle and last={\draw[red,line width=3.5pt] ([xshift=4mm,yshift=-1.5mm]frame.north west) -- ([xshift=4mm,yshift=1.5mm]frame.south west); },
  #1}
  {\raggedright #2%\qed
  }

更新：

• 按章节内的编号，添加number within=chapter到框的初始化选项。

• 要标记单个框，请将其添加label=mylabel到引理或证明的选项列表中。

以下是显示应用程序的代码：

Answer 2

由于时间不足和对 TikZ 缺乏了解，这不是一个完整的解决方案，而是一个起点；-)

我尝试使用tcolorbox易碎和覆盖功能及其theorem样式来制作盒子。bclogo可以插入包装上的徽标，但我无法正确定位它们。这也导致盒子内容向右移动。

\documentclass[paper=a4,12pt]{scrbook}

\usepackage{etoolbox}%
\usepackage{blindtext}%
\usepackage{bclogo}%
\usepackage[theorems,skins,breakable]{tcolorbox}%


\begin{document}

\chapter{First}


\section{First}

\newtcbtheorem[number within=section]{lem}{Lemma}%
{overlay={\bclampe},left=5pt,breakable,colback=green!5,colframe=green!35!black,fonttitle=\bfseries,title after break={Lemma \csuse{the\tcbcounter} -- \raggedleft Continued}}{lem}

\newtcbtheorem[number within=section]{proof}{Proof}{breakable,overlay={\bclampe},colback=green!5,colframe=green!35!black,fonttitle=\bfseries,title after break={Proof \csuse{the\tcbcounter} -- \raggedleft Continued}}{prf}
