Chemnum 不会替换 eps 文件中的 TMP 标记

Chemnum 不会替换 eps 文件中的 TMP 标记

我是 Latex 的新手，但真的很想用它来写我的论文（当然是化学）。实验室工作快完成了，但这似乎是目前较低的障碍 :D

现在，我正尝试使用 chemnum 包来为所有化合物获取漂亮的标签。理论上，它应该用自动编号替换“TMP”标记（由 chemdraw 软件创建的外部 eps 文件中给出）。但是，我甚至无法使用 TeXstudio 运行示例文件：

https://de.overleaf.com/latex/templates/automatically-numbering-compounds-in-chemical-schemes/kybckmsxnshs

在我的例子中，标记没有被替换，而是在所有六个示例化合物下都写有文本“TMP1”或“TMP2”。此外，图片内的字体相对于上面的模型 pdf 来说也是乱七八糟的。

我做错了什么？我们来谈谈这个问题：我该如何制作自己的 TMP 标签？在 chemdraw 中将“TMP”写为文本块可以吗？

提前致谢！

因此，我得到了一些额外的线索：它可能与编译设置有关。

如前所述，使用 overleaf texmaker 可以在线编译。Overleaf 使用 latex 编译，但当更改为 pdflatex 时，它无法重新印制 TMP 标记，但是，图形仍然看起来正确。我的设置已经无法描绘图片（见下面的屏幕截图，请注意随机部分缺失/移动并且字体已更改）。

使用 auto-pst-pdf 命令根本不会产生任何图像。

enter\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{graphicx}
\title{Automatically numbering compounds in chemical schemes}
%% Uncomment these lines if you get error about "too many \new..." 
% \let\tmp\newinsert
% \let\newinsert\newbox
\usepackage{chemstyle}
% \let\newinsert\tmp
\usepackage{chemnum}
% For positioning the scheme captions at the top.
\floatsetup[scheme]{position=top}

\begin{document}
\begin{scheme}
%% hexa.eps has "TMP1" and "TMP2" as the markers
%% in fact EVERY .eps should start with TMP1, TMP2 etc

您描述的问题是 pdfLatex / chemnum / Texstudio / ChemDraw 组合中的常见问题。化合物编号在化学论文中显然非常重要。

我的回答基于类似问题的答案，请参阅：编号/ChemDraw/Mac，EPS/ChemDraw/chemnum，正确的 Texstudio 配置，

我将尝试在下面列出最常见的错误来源：

  1. 编译：你需要pdflatex -synctex=1 -interaction=nonstopmode --shell-escape %.tex在TexStudio中使用

  2. Texstudio PATH：根据您的操作系统，将您的 PATH 设置为类似的值/usr/local/texlive/2019/bin/x86_64-darwin:/Library/TeX/texbin（您必须根据您的操作系统进行调整）。

  3. Auto-pst-pdf：您需要\usepackage[crop=off,runs=2]{auto-pst-pdf}在序言中尽早加载。

  4. EPS：需要以一种明确定义文本字符串的方式进行。Windows 上的 ChemDraw 可以很好地完成此操作（导出的标准参数），但 Mac 上的 ChemDraw 则不行。这是一个错误，也是一个前一个问题调查了一下。因为我可以编译你的 MWE，所以我认为你没问题。

我之前不知道 jobname 注释，对于 TexStudio 我不需要它，但对于 Overleaf 来说可能是必要的？

此示例对我有用，使用上面描述的设置，使用 TexStudio v3：

\documentclass{article}
%\def\jobname{main} %<-- your file name
\usepackage[
runs=2,
crop=off
]{auto-pst-pdf} 
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{graphicx}

% For positioning the scheme captions at the top.
%\floatsetup[scheme]{position=top}

    \begin{document}

    \vfill

我没有资格评论你的答案。如果你仍然想使用 pdflatex 作为编译器，我建议重命名“\jobname”，就像 Ulrike Fischer 在这里的答案中所做的那样这里。

使用您引用的背面示例并添加行来重命名\jobname并且该{auto-pst-pdf}包对我有用。

\documentclass{article}
\def\jobname{main} %<-- your file name
\usepackage[
%runs=2,
%crop=off
]{auto-pst-pdf}

\usepackage{lmodern}
\usepackage{graphicx}

%\floatsetup[scheme]{position=top}

如果您在 MacOS 上使用 Chemdraw，请查找此帖子： https://tex.stackexchange.com/a/687480/298255

该解决方案对于 Windows 用户也可能有帮助。
