在單個四開本PDF輸出中創建多頁方向

rmarkdown這個想法是在in上復制 PDF 輸出quarto，在這種情況下，是在單個檔案上創建多頁方向。在rmarkdown我可以通過使用這個技巧輕松做到這一點。但是，我無法在 quarto 中做到這一點，它一直在發送錯誤訊息

compilation failed- error 
Undefined control sequence.
l.201 \blandscape

這是我的代碼：

---
title: "Portrait and Landscape"
format:
  pdf:
    include-in-header:
      - packages.tex
---

# Quarto

Quarto enables you to weave together content and executable code into a finished document. To learn more about Quarto see <https://quarto.org>.

\newpage
\blandscape

# Running Code

When you click the **Render** button a document will be generated that includes both content and the output of embedded code. You can embed code like this:

You can add options to executable code like this 

The `echo: false` option disables the printing of code (only output is displayed).

\elandscape

有趣的是，我可以通過修改 YAML 并插入原始乳膠來開始和結束橫向頁面來創建多頁面方向，但它會洗掉所有rmarkdown格式并將其轉換為橫向頁面內的普通文本：

---
title: "Portrait and Landscape"
format: 
  pdf:
    include-in-header:
        text: |
           \usepackage{pdflscape}
---


\begin{landscape}

bla bla bla

\end{landscape}

有沒有解決這個問題的方法？

PS：我的 header.tex 包含這些東西

\usepackage{pdflscape}
    \newcommand{\blandscape}{\begin{landscape}}
    \newcommand{\elandscape}{\end{landscape}}

uj5u.com熱心網友回復：

選項 01

您可以使用lscape LaTeX包。這會旋轉頁面內容，但不會旋轉頁碼。

您也可以使用typeareaKOMA-Script 包來執行此操作。據我了解，它不僅改變了頁面內容的方向，而且還設定了 pdf 頁面旋轉屬性，使得具有該屬性的頁面在使用 PDF 查看器查看時將以橫向顯示。并且還保留了頁碼位置。
