问题

我怎样才能重新调整 TikZ 的尺寸变量以适应文档中间的尺寸变化，就像这样例子并使用 TikZ 绘图这里。

问题

TikZ 坐标不在应在的位置。请参阅这个例子以便在页面上正确对齐坐标。

标准

只是为了澄清：

  • 页面尺寸必须正好是高度=224mm、宽度=130mm（托盘尺寸）
  • 磁盘原点必须精确位于页面顶部以下 -119.98 毫米 ( current page.north)

程序

我设置了 DVD 托盘的自定义长度：

\newlength{\pagewidthDVDTray}
\newlength{\pageheightDVDTray}
\setlength{\pagewidthDVDTray}{130mm}
\setlength{\pageheightDVDTray}{224mm}

我创建了一个为几何包创建新几何的命令：

\newcommand{\generatePageLayouts}{%
  \newgeometry{layoutwidth=\pagewidthDVDTray,layoutheight=\pageheightDVDTray,left=0mm,right=0mm,bottom=0mm,top=0mm}
  \savegeometry{LayoutPageDVDTray}
}%

我创建了一个切换到新布局的命令：

\newcommand{\switchToLayoutDVDTray}{%
  \pdfpagewidth=\pagewidthDVDTray \pdfpageheight=\pageheightDVDTray % for PDF output
  \paperwidth=\pagewidthDVDTray \paperheight=\pageheightDVDTray     % for TikZ
  \loadgeometry{LayoutPageDVDTray} % note; \loadgeometry may reset paperwidth/h!
}

我立即加载了命令\begin{document}

\generatePageLayouts
\switchToLayoutDVDTray

情况

我有一个共享的序言，它必须具有如下所示的特定尺寸：

\usepackage[%
     a4paper,
     head=1.5cm,%\baselineskip,  % distance from bottom of header to block of text aka \headsep e.g. \baselineskip
     foot=1.5cm,  % distance from top of footer to block of text aka \footskip
     headheight=12pt,     % height for the header block (no equivalent for footer)
     marginparwidth=2cm,  % right marginal note width
     marginparsep=2mm,    % distance from text block to marginal note box
     top=2.5cm,           % distance of the text block from the top of the page
     bottom=3cm,
     left=2.5cm,
     right=2.5cm,
 ]{geometry}

我的一个文档需要使用序言中的许多变量，但纸张大小不同。更改 TikZ 的页面尺寸被证明很困难。

示例代码

\documentclass[10pt]{article}
\usepackage[quiet]{fontspec}
\usepackage[%
     a4paper,
     head=1.5cm,%\baselineskip,  % distance from bottom of header to block of text aka \headsep e.g. \baselineskip
     foot=1.5cm,  % distance from top of footer to block of text aka \footskip
     headheight=12pt,     % height for the header block (no equivalent for footer)
     marginparwidth=2cm,  % right marginal note width
     marginparsep=2mm,    % distance from text block to marginal note box
     top=2.5cm,           % distance of the text block from the top of the page
     bottom=3cm,
     left=2.5cm,
     right=2.5cm,
 ]{geometry}
\newlength{\pagewidthDVDTray}
\newlength{\pageheightDVDTray}

\setlength{\pageheightDVDTray}{224mm}

你只需要像这样重新定义这两个命令

\newcommand{\generatePageLayouts}{%
  \newgeometry{layoutwidth=\pagewidthDVDTray,layoutheight=\pageheightDVDTray,left=0mm,right=0mm,bottom=0mm,top=0mm}
  %\savegeometry{LayoutPageDVDTray}
}%
\newcommand{\switchToLayoutDVDTray}{%
  \pdfpagewidth=\pagewidthDVDTray \pdfpageheight=\pageheightDVDTray % for PDF output
  \paperwidth=\pagewidthDVDTray \paperheight=\pageheightDVDTray     % for TikZ
  %\loadgeometry{LayoutPageDVDTray} % note; \loadgeometry may reset paperwidth/h!
}

此外你不需要

\generatePageLayouts

根本

编辑：或者你可以重新定义

\newcommand{\switchToLayoutDVDTray}{%
\loadgeometry{LayoutPageDVDTray} %
\pdfpagewidth=\pagewidthDVDTray \pdfpageheight=\pageheightDVDTray % for PDF output
\paperwidth=\pagewidthDVDTray \paperheight=\pageheightDVDTray     % for TikZ
 }

为什么？要更改 pdfpagewidth 和 height，您需要 newpage。loadgeometry 执行此操作，但您必须稍后调用它

编辑：更多解释

当我们打电话时

\generatePageLayouts

我们保存了一个新的几何图形

layoutwidth=\pagewidthDVDTray,layoutheight=\pageheightDVDTray,left=0mm,right=0mm,bottom=0mm,top=0mm

但我们在这里隐式保存了纸张尺寸 a4。接下来当我们调用

\switchToLayoutDVDTray

我们定义新的 pdfpage 大小

\pdfpagewidth \pdfpageheight

和纸张尺寸 \paperwidth \paperheight 但此纸张尺寸将被破坏

\loadgeometry{LayoutPageDVDTray}

激活已保存的几何图形，因此纸张大小为 a4。现在 pdfpage 正确为 = 224*130，但 tikz 眼中的纸张大小（如 OP 的代码中所述）为 a4，并且当前 page.north 位于顶部，距左侧 105 毫米处，而不是 65 毫米处。
