Error in including pdf figures with \includegraphics; no BoundingBox!

最近 TeX で文章を書いていて、pdf で作成したグラフを読み込もうとしたところ、bb ファイルをちゃんと作成してたはずが、

LaTeX Error: Cannot determine size of graphic in fig2.5.pdf (no BoundingBox).

というエラーに見舞われました。

いろいろと試行錯誤したのですが、結局ファイル名に "." が含まれていると正常に処理できない事が原因だったようです。今後は気をつけよう。

\documentclass{jsarticle}

\usepackage[dvipdfmx]{graphicx} 

\begin{document}

\begin{figure}[!htb]
\begin{center}
% \includegraphics[clip,width=0.95\textwidth]{fig2.5.pdf}
\includegraphics[clip,width=0.95\textwidth]{fig25.pdf}
\end{center}
\caption{
If "." is included in the filename, an error will occur;
{\bf LaTeX Error: Cannot determine size of graphic in fig2.5.pdf (no BoundingBox).}
}
\end{figure}

\end{document}
