举例来说
\begin{tikzpicture}
\node[\@photoshape, draw=\@photoborder, line width=0.3mm, inner sep=\photodim, fill overzoom image = \@photo ] () {};
\end{tikzpicture}
我得到了错误
Package pgfkeys Error: I do not know the key '/tikz/fill overzoom image' and I am going to ignore it.
Perhaps you misspelled it.
See the pgfkeys package documentation for explanation.
Type H <return> for immediate help.
