在包含 A3 和 A4 纸张尺寸的文档中居中标题

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？

A3 文档标题未居中

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：

答案2

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。

A4之后是A3纸
