为什么在下面的例子中会出现尺寸过大的错误以及如何修复它：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations.markings}
\begin{document}
\begin{tikzpicture}
\draw[red,decoration={
markings,
mark=
between positions 0 and 1 step 1cm
with
{
\draw (0,0) circle (1pt);
}
},
postaction=decorate
] plot[smooth] coordinates {(1,4.5) (2,5) (7,4.5)};
\end{tikzpicture}
\end{document}
