所以我注意到当\hoffset或\voffset改变时，TikZ 不再找到正确的原点。 是否可以帮助 TikZ 找到正确的原点？（比如全局转移之类的？）

另外，为什么该geometry包不首先设置\hoffset并\voffset设置为-1in，而是稍后将其包含在计算中？无论如何，它使用\def\Gm@magtooffset{%并提到每个偏移量 4 次，因此它会对它们进行处理。

无论如何，在查看几何代码之前，我曾尝试编写自己的代码。我注意到我会怎么做不同于几何是如何做到的，我称之为自上而下、从左到右的方法和固定正文文本区域方法， 分别。

自上而下、从左到右的方法

仅凭信息\topmargin就让我发疯。甚至size10.clo包含

 \addtolength\topmargin{-\footskip}     % this might be wrong!

我认为它是错误（除非通过除以 2 来完美居中正文区域，我猜当它乘以 0.5 时就可以做到这一点）

  1. 首先反转 1 英寸的内置 TeX 边距。

自顶向下

  1. 放\headheight
  2. 放\headsep
  3. 放\footskip
  4. 由此计算\topmargin和\textheight。

左右

  1. 从...开始\oddsidemargin
  2. 由此计算\textwidth

请注意，即使我将偏移量设置为 0，并从 oddsidemargin 和 topmargin 中减去 1 英寸，TikZ 也无法通过此方法找到正确的原点。 另请注意，我不需要或不打算在文档中使用边注，因此我只需将这些值设置为零。

固定正文文本区域方法

从geometry包中： 在此处输入图片描述

\topmargin请注意固定的文本高度和文本宽度（用作其他计算的基础）以及此代码如何在和的计算中减去 1 英寸\oddsidemargin，我认为这是为了否定 1 英寸的内置 TeX 边距。

这两个方法均未注释，这意味着底部方法将覆盖第一个方法。固定正文文本区域方法位于下方，且在此优先。

输出 hoffset 和 voffset 设置为 -1in

在此处输入图片描述

输出 hoffset 和 voffset 不变

在此处输入图片描述

答案1

答案似乎是双重的。

不要改变偏移量，因为

  1. 许多包（可能错误地）依赖于\hoffset并且\voffset为 0。摘要：不要改变它。（除非计算机与打印机接口存在问题） - 感谢 egreg
  2. 蒂克兹做如果从边距中取出 1 英寸，则找到正确的页面原点。

我很固执，无论如何我都会改变 hoffset 和 voffsets！

不建议这么做。 调整的方法tikzpagenodes是在加载后添加此项并删除英寸调整：

\def\current@textarea@left{(-1in+\hoffset+\currentsidemargin)}
\def\current@textarea@top{(-1in+\voffset+\topmargin+\headheight+\headsep)}

我还不确定该如何做tikz，或多或少是因为有很多文件需要整理。

我对包裹假设的思考

盲目地依赖偏移量为 0 似乎并不是一个好主意。例如，如果我真的有打印错误怎么办（正如 egreg 在评论中提出的现实情况）？我需要稍微调整一下偏移量，在这种情况下，TikZ 覆盖坐标会偏离相同的量。这是一个小问题，但对齐对于视觉上吸引人的文档很重要。
