调整字体大小以达到假透视效果

我想在左侧的路径上添加文本，字体大小从到连续调整，\Huge以实现\tiny类似透视的效果。字体大小步骤不应该是\Huge、、、…… ，但字体大小也应该取列出的大小之间的值。\huge\LARGE\tiny

我想实现这样的目标：

并将其放在第一个图形的路径上。

编辑#1

使用\foreachTikZ，我成功地获得了一个角色几乎所需的效果。

\newcommand\myfontsize[1]{\fontsize{#1}{10}\selectfont}

\begin{tikzpicture}
    \foreach \x in {22.82086,...,6.80565}
    {
        \draw (-\x, 0) node {\myfontsize{\x}a};
    }
\end{tikzpicture}

但我仍然不知道如何将其应用于一系列字符（例如一个句子），并将文本放在路径上。

编辑#2

进一步阅读 TikZ 手册后，我发现我可以同时迭代两个变量。这允许我在迭代中为每个字符使用不同的字体大小。

\begin{tikzpicture}
    \foreach \i/\char in {22.82086/a,18.8170575/b,14.813255/c,10.8094525/d,6.80565/e}
    {
        \draw (-\i, 0) node {\myfontsize{\i}\char};
    }
\end{tikzpicture}

但是我必须在\foreach循环中明确指定步长。因此，这引发了一个问题：如何根据要打印的字符数计算步长。

答案1

我在这个问题上找到了问题的答案使用 TikZ 制作螺旋状文本。所有荣誉都归于原始答案。

包含以下宏后，您可以在装饰选项中使用text path start scale=2.4和text path end scale=0.5键值对。

\makeatletter

\let\pgf@lib@dec@text@dobox@original=\pgf@lib@dec@text@dobox%

\def\pgf@lib@dec@text@dobox{%
    \pgf@lib@dec@text@dobox@original%
    \ifpgfdecorationtextalongpathscaletext%
    \pgfmathparse{\pgf@lib@dec@text@endscale+(\pgf@lib@dec@text@startscale-\pgf@lib@dec@text@endscale)*\pgfdecoratedremainingdistance/\pgfdecoratedpathlength}%
    \setbox\pgf@lib@dec@text@box=\hbox{\scalebox{\pgfmathresult}{\box\pgf@lib@dec@text@box}}%
    \fi%
}
\newif\ifpgfdecorationtextalongpathscaletext
\def\pgf@lib@dec@text@startscale{1}
\def\pgf@lib@dec@text@endscale{1}

\pgfkeys{/pgf/decoration/.cd,
    text path start scale/.code={%
        \pgfdecorationtextalongpathscaletexttrue%
        \def\pgf@lib@dec@text@startscale{#1}%
    },
    text path end scale/.code={%
        \pgfdecorationtextalongpathscaletexttrue%
        \def\pgf@lib@dec@text@endscale{#1}%
    }
}

请参阅LEFT_1问题中的路径并将其替换为以下内容：

% LEFT_1
\path[decorate,%
    decoration={text along path,%
    text path start scale=2.4,
    text path end scale=0.5,
    text={vso nbl dsfn klijvb sodvn},%
    text align={fit to path stretching spaces}},%
    cm={{0.55521796,0.0,0.0,0.55521796,(-142.0,95.56731)}}]
    (682.8721,718.1295) -- (940.1713,512.2902);

输出将是：
