使用 epstopdf 时遇到巨大问题

Question

我在 Windows 上使用 TeXstudio。我的 LaTeX 文件位于 C:/Users/Documents 我的图像位于同一位置。

\documentclass[preprint,12pt,3p]{elsarticle}
\newif\ifpdf
\ifx\pdfoutput\undefined
\pdffalse
\else
   \pdfoutput=1
   \pdftrue
\fi
\ifpdf
   \usepackage{graphicx}
   \usepackage{epstopdf}
   \DeclareGraphicsRule{.eps}{pdf}{.pdf}{`epstopdf #1}
   \pdfcompresslevel=9
\else
   \usepackage{graphicx}
\fi

    \usepackage{amsfonts,amssymb,amscd,amsmath,enumerate,verbatim,calc,float,wrapfig}

\usepackage[export]{adjustbox}

\epstopdfsetup{suffix=}
\begin{document}
\section{intro}
\begin{figure}[H]
\centering
\includegraphics{Figure 2.eps}
\end{figure}
\end{document}

日志文件显示：

! Package pdftex.def Error: File `Figure 2.pdf' not found: using draft setting.
LaTeX Warning: File `Figure 2.eps' not found on input line 59.

Type  H <return>  for immediate help.

l.59 \includegraphics{Figure 2.eps}
Overfull \hbox (2.61108pt too wide) has occurred while \output is active

现在，如果我只说 \includegraphics{Figure 1} 而不带 eps 扩展名，那么日志文件如下：

! LaTeX Error: File `Figure 2' not found.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.59 \includegraphics{Figure 2}

I could not locate the file with any of these extensions:
.pdf,.png,.jpg,.mps,.jpeg,.jbig2,.jb2,.PDF,.PNG,.JPG,.JPEG,.JBIG2,.JB2,.eps,.ep
s
Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit.


Overfull \hbox (2.61108pt too wide) has occurred while \output is active

如果我在 epstopdfsetup 中使用 outdir，我该如何根据文件位置来写入它？我的文件位置有问题吗？图像和源文件都位于同一文件夹中。
