使用 scrlttr2 和 tcolorbox 環境重新定義引用環境的雙面模式下的額外行間距

scrlttr2在與 結合使用引用時嘗試兩側設定時tcolorbox，我遇到了一個奇怪的情況。以下範例顯示了引用環境框之外的文字中的行間距。這僅在雙面模式下顯示，並且僅在重新定義 的呼叫beforeafter skip=\baselineskip中出現。我很困惑是什麼導致了這種情況，因為它與引用環境或兩側性沒有明顯的聯繫。tcolorboxenvironmentquoting

產生的 2 頁文件的第一頁如下所示，其中顯示了問題

在此輸入影像描述

答案1

當使用twoside時，類別會啟動（就像其他類別經常做的那樣）\flushbottom。這意味著 LaTeX 將嘗試填充頁面，並為此拉伸 parskip。

如果刪除beforeafter skip=\baselineskip,as 則效果會消失，然後該字母適合一頁。

在 oneside 模式下，如果 add ，您會得到相同的結果\flushbottom。

為了避免這個問題添加\raggedbottom

答案2

自 3.17 版本以來，\flushbottom在雙面模式下使用是一個錯誤。scrlttr2它已在scrlttr2v3.27.3111 中透過添加\raggedbottom環境定義進行修復letter。在此變更之前

\documentclass[twoside]{scrlttr2}

\usepackage{mwe}

\begin{document}
\begin{letter}{You\\There}
  \opening{Hi,}
  \blindtext\par\blindtext

  \noindent\rule{\textwidth}{.5\textheight}

  \blindtext
  \closing{Bye}
\end{letter}

\end{document}

結果出現警告訊息：

Underfull \vbox (badness 10000) has occurred while \output is active [1

和

使用 KOMA-Script 3.26b

使用 KOMA-Script 3.27.3111（這是KOMA-Script 預發布），其結果是：

來自 KOMA 腳本 3.27.3111

沒有警告訊息。

注意，還有額外的即將推出的 KOMA-Script 3.27 中的更改（德語連結頁面）。
