演示tikz中文字沿路径摆放

演示tikz中文字沿路径摆放:

%演示文字沿路径摆放 
begin{tikzpicture}
path decorate [decoration={text along path,
text={some text along a path}}]{ (0,2) .. controls (2,2) and (1,0) .. (3,0) }; 
draw  (0,2) .. controls (2,2) and (1,0) .. (3,0);  
end{tikzpicture}  

但是tikz没有封装命令decorate,但是下面的用法是可以的:

tikz draw decorate[decoration=zigzag] {(0,0) -- (3,0)};

pgfdeclaredecoration{stars}{initial}{
state{initial}[width=15pt]
{
pgfmathparse{round(rnd*100)}
pgfsetfillcolor{yellow!pgfmathresult!orange}
pgfsetstrokecolor{yellow!pgfmathresult!red}
pgfnode{star}{center}{}{}{pgfusepath{stroke,fill}}
}
state{final}
{
pgfpathmoveto{pgfpointdecoratedpathlast}
}
}
tikzpath[decorate, decoration=stars, star point ratio=2, star points=5,
inner sep=0, minimum size=rnd*10pt+2pt]
(0,0) .. controls (0,2) and (3,2) .. (3,0)
.. controls (3,-3) and (0,0) .. (0,-3)
.. controls (0,-5) and (3,-5) .. (3,-3);
