我在 Powerpoint 中创建了一个绘图并将其保存为 .pdf
然后我将其转换为 .eps
然而尝试使用 psfrag 似乎不起作用：
尝试 1
pdflatex --shell-escape
\documentclass{article}
\usepackage{pstool}
\begin{document}
\begin{center}
\psfrag{A}{\textit{test}}
\psfragfig{Presentation6}
\end{center}
\end{document}
输出：
这基本上就是原始图像。
尝试 2
pdflatex --shell-escape
\documentclass{article}
\usepackage{auto-pst-pdf}
\begin{document}
\begin{center}
\begin{postscript}
\psfrag{A}{\textit{test}}
\includegraphics{Presentation6.eps}
\end{postscript}
\end{center}
\end{document}
输出：
尝试 3
latex dvips ps2pdf
我使用 quickbuild
\documentclass{article}
\usepackage{graphicx,psfrag}
\begin{document}
\psfrag{A}{\textit{test}}
\includegraphics{Presentation6.eps}
\end{document}
输出：
设置：
问题
如何替换用 powerpoint 创建的图像中的文本？

答案1
该Tj操作符（将在 EPS 标头中定义）正在实现同名的 PDF 操作符，并且可能根据xshow（在应用字母间字距调整时显示 PostScript 字符串）进行定义。如前所述在先前的回答中 psfrag永远不会重载，xshow因此您可以通过替换它来简化代码，show或者直接替换
(A) [10.422 0] Tj
经过
(A) show
这样psfrag超载就show生效了。
（这都是很久以前的事了，但我不明白为什么psfrag不能重载xshow定义它来忽略数组而只将字符串视为处理字符串参数show，这样可以节省手动编辑 EPS 文件的时间。）
