将 tikzpagenodes 与 crop 包一起使用？

Question 1

这是第三个答案。如图所示，这不会更正添加的节点的位置。相反，它弥补了在部分缩略图配置的有限上下文中出现的tikzpagenodes谎言。crop

Question 2

好的，我想我有一些方法，但并不完全确定；解决方法似乎是这样的：

\ifx\CROP@size\undefined
  \typeout{CROP@size undefined}
\else
  \typeout{CROP@size defined}
  % must set via newlength so it survives descent into tikzpicture!
  \setlength\gparindent{\parindent}
  \setlength\gbaselineskip{\baselineskip}
  \def\current@textarea@left{(1in+\hoffset+\currentsidemargin-\Gm@lmargin-\gparindent)}
  \def\current@textarea@top{(1in+\voffset+\topmargin+\headheight+\headsep)+2*\[email protected]\gbaselineskip}
\fi

...也就是说，如果crop已加载，则重新定义\current@textarea@left和\current@textarea@top来自tikzpagenodes，因此左侧由调整\Gm@lmargin-\gparindent，右侧由- 其中/是通过包调整的边距。2*\[email protected]\gbaselineskip\Gm@ltmargingeometry

\gparindent和是 parindent/baselineskip 的“全球化”版本\gbaselineskip- 作为长度 - 否则当上述定义在内部运行时它们不会传播tikzpicture（这会重置 parindent/baselineskip）。Gm@ 边距是有意义的，但我不知道为什么一开始会有这个位移 - 我通过反复试验找到了修复值，所以买者自慎。

下面的代码有一些额外的调试内容，它输出如下内容：

似乎还有少量的出血 - 这很好；而且，如果你只是评论这些crop行，一切似乎都有效。

Question 3

crop似乎从根本上不同意tikzpagenodes。或者，更确切地说，按照crop要求撒谎，似乎从根本上不同意。这并不奇怪。如果文本区域不在你说的地方，事情出问题也就不足为奇了。

如果geometry裁切标记是一种选项，那么这些可以正常工作：

带有精美部分的裁剪标记

Question 4

我一直在从更普遍的角度研究这个问题。

通过扫描包装的文档crop，似乎我们想要提取的最相关的值是\stockwidth和\stockheight，它们用于存储最终的纸张尺寸。

我们真正需要做的就是重新定义的主要宏，以tikzpagenodes解释\stock*和之间的差异\paper*。此代码为

\def\current@textarea@left{%
  (1in+\hoffset+\currentsidemargin+.5*(\paperwidth-\stockwidth))%
}
\def\current@textarea@top{%
  (1in+\voffset+\topmargin+\headheight+\headsep-.5*(\stockheight-\paperheight))%
}

\stock这只是将和值之间的差值相加一半\paper来解释偏移量。我们只需要一半的值，因为逻辑页面位于物理页面的中心，因此偏移量为差值的一半。

为了制作此产品的通用版本，我们将执行以下操作：

%fix the crop issue with tikzpagenodes
\@ifpackageloaded{crop}{
  \@ifpackagewith{crop}{center}
    {
    \def\current@textarea@left{%
      (1in+\hoffset+\currentsidemargin+.5*(\paperwidth-\stockwidth))}
    \def\current@textarea@top{%
      (1in+\voffset+\topmargin+\headheight+\headsep-.5*(\stockheight-\paperheight))}
    }
    {
    \def\current@textarea@top{%
      (1in+\voffset+\topmargin+\headheight+\headsep-(\stockheight-\paperheight))}
    }
  }
  {%
}

现在，如果加载了裁剪包，我们可以自动调整偏移量。我还针对center未使用该选项的情况进行了不同的调整，此时很好\hoffset，因此不需要调整，而\voffset需要两倍的调整（因为我们位于页面的左上角）。

我在排版 RTL 和 LTR 文本时使用 XeTeX 对此进行了测试。

这实际上很有趣，因为该center选项实际上设置了\hoffset符合\voffset我们需求的值，但调查这一点并不是必要的。
