几个月前，我通过 MikTeX 更新了 TeXworks，现在每次尝试使用时都会收到以下警告消息epstopdf：“PDF 包含：发现 PDF 版本 <1.7>，但最多允许版本 <1.5>”
更新之前我没有遇到任何问题。以下是 MWE：
\documentclass[12pt]{article}
\usepackage{graphicx}
\usepackage{epstopdf}
\begin{document}
\begin{figure}
\includegraphics[width=5in]{Phaselock.eps}
\end{figure}
\end{document}
eps 文件可以在这里找到：https://drive.google.com/file/d/1Gx5khDOo4Vovz0Z8TFV6CpNpQF3fuk20/view?usp=sharing
我已经尝试\pdfminorversion=7在文档类行之前、文档类行之后和之前使用\begin{document}。在这种情况下，我不再收到有关 PDF 版本的消息，但创建的 eps 图形的 PDF 文件不是它应该的样子（字体是块状的，图形轴上的刻度与轴重叠。）我在运行上述代码后粘贴了日志文件的内容和 \pdfminorversion=7紧接着\begin{document}。我没有主意了，并且尝试了其他帖子中建议的几行代码，例如：
\epstopdfDeclareGraphicsRule{.eps}{pdf}{.pdf}{%
epstopdf --gsopt=-dCompatibilityLevel=1.5 #1 --outfile=\OutputFile}
任何帮助深表感谢！！

答案1
事实证明，真正的问题是我没有helvetic安装该软件包。\pdfminorversion=7解决方案确实有效，现在 PDF 中的字体由于该helvetic软件包而正确。感谢@UlrikeFischer 指出真正的问题并纠正我对问题根源的假设。
答案2
以下示例使用 成功编译pdflatex。您可能需要Phaselock-eps-converted-to.pdf在编译之前删除该文件。
笔记：
- 无需加载
epstopdf包，因为graphicx现在会自动加载epstopdf-base包。 .eps并且可以省略文件扩展名（ ）。
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}
\includegraphics[width=5in]{Phaselock}
\end{figure}
\end{document}
这是我得到的：
