![在包含 A3 和 A4 纸张尺寸的文档中居中标题](https://linux22.com/image/375939/%E5%9C%A8%E5%8C%85%E5%90%AB%20A3%20%E5%92%8C%20A4%20%E7%BA%B8%E5%BC%A0%E5%B0%BA%E5%AF%B8%E7%9A%84%E6%96%87%E6%A1%A3%E4%B8%AD%E5%B1%85%E4%B8%AD%E6%A0%87%E9%A2%98.png)
为了将多幅图放在一行上,我的文档有 A4(纵向)和 A3(横向)页面。为了设置 A3 页面,我创建了一个新环境(我从另一个解决方案中改编的技巧)。请注意,我无法为 A3 页面创建单独的 PDF 并将其添加进去,因为图引用、页面、部分等会不断变化。
但是,当我在 A3 页面上绘制图形时,主标题的位置就像 A4 一样。(见下文)如何将标题相对于 A3 页面居中?
我在 A4 部分中包含了不带文本的代码:

答案1
页面布局还有很多东西,不仅仅是众所周知的参数,例如\textwidth
。例如,TeX 内部使用\hsize
来构建段落。最好的方法是,将其留给geometry
。
不幸的是,\newgeometry
不允许在纵向和横向之间切换或在文档中更改纸张大小。但可以编写一个宏,允许这样做。它基本上是 的更改副本\newgeometry
,\newgeometryfull
在此处调用。请小心使用它!此外,必须设置\pdfpageheight
和\pdfpagewidth
,以便 PDF 查看器也知道纸张大小。这是在a3page
环境中完成的。
我删除了该行\headwidth=\textwidth
,因为\headwidth
在您的示例中不存在。但您可能需要它来处理此处不存在的标题。
结果:
代码:
\documentclass[12pt]{article}

这是我不太优雅的解决方案。我用
\eject \pdfpagewidth=16.5in \pdfpageheight=11.7in
使页面具有不同的大小。此解决方案基于此回答。现在标题已居中。
