如何使用 \pgftransformcm 和 \inheritsavedanchors 从椭圆形创建新形状（蝙蝠侠）

我尝试做出这种形状但遇到了几个问题。

  1. 首先将徽标放在椭圆内，我使用了\pgftransformcm{1}{0}{0}{1}{\centerpoint}也许有更好的解决方案。我需要\pgftransformcm{-1}{0}{0}{1}{\centerpoint}在最后使用，因为文本是反转的，但是随着所有转换，我失去了基线并且文本放错了位置。这是主要问题

  2. 我尝试使用\inheritsavedanchors但没有成功

  3. 为了获得良好的结果，我认为保持高度和宽度之间的比例很重要，但如何做到这一点？

  4. 也许计算不正确，但我更愿意在重新进行所有计算之前先了解我需要做什么。可以使用高度/宽度比率来获得更好的结果。

这是长代码，当我固定尺寸时结果很好。

使用下面的代码，结果是正确的

  \begin{tikzpicture}

 \node[draw,shape=batman,minimum height=8.2cm,minimum width=14cm,text=white] (B) at ([yshift=-12cm]A) {\Huge Bat me down  };
\draw [red,ultra thick,double,->](A) --(B);
  \end{tikzpicture}

与

  \begin{tikzpicture}
\node[draw,shape=batman,text=white] (A) {\Large Bat me up};  

 \node[draw,shape=batman,text=white] (B) at ([yshift=-3cm]A) {\Huge  Bat me down  };
\draw [red,ultra thick,double,->](A) --(B);

这非常糟糕（比例文本等）

答案1

您需要包含您的变换，pgf并进行自己的变换来放置其节点，因此您需要尊重这一点。当您在另一个变换之上进行变换时，就会出现问题。

您可以通过在第一个组之前放置一个组\pgftransformcm并在背景路径的底部放置一个结束组来避免这种情况。

  %
  % Background path
  %
  \backgroundpath
  {
    % commented out...
    % interesting drawing...
    % commented out...
   \bgroup
   \pgftransformcm{1}{0}{0}{1}{\centerpoint}        
  \pgfpathmoveto{\pgfpoint{0 cm}{0.66\batmany}}
  \pgfpathlineto{\pgfqpoint{0.07\batmanx}{0.66\batmany}}
  \pgfpathlineto{\pgfqpoint{0.14\batmanx}{0.793\batmany}}
  \pgfpathcurveto{\pgfqpoint{0.17\batmanx}{0.317\batmany}}
                 {\pgfqpoint{0.186\batmanx}{0.24\batmany}}
                 {\pgfqpoint{0.28\batmanx}{0.24\batmany}}
  ...
  ...
  ...
  \pgfpathmoveto{\pgfpoint{0 cm}{0.66\batmany}}    
  \pgfsetfillopacity{1}%  
  \pgfsetfillcolor{black}%  
  \pgfusepath{fill,stroke}
  \egroup
  \pgfsetlinewidth{0.4pt}% 
  }

然后您的文本将显示在text锚点处。

在此处输入图片描述

为了保持一定的纵横比，您应该计算高度和宽度。检查用户给出的数值，然后根据任何规定的方法从其中之一计算比率。这可以通过简单的 if 和检查来完成，相当于以下内容，可以扩展以满足您的需求：

    % Calculate height, this example puts a minimum height of the
    % shape dependent on the text contained.
    \pgfmathsetlength\pgf@ya{\pgfkeysvalueof{/batman/minimum height}}%
    \pgf@y=2\ht\pgfnodeparttextbox%
    \ifdim\pgf@y<\pgf@ya%
       \pgf@y=\pgf@ya%
    \fi%
    % do more computational work...
    ...
    % You could do checks of aspect ratio, which I would recommend:
    \pgf@ya=.25\pgf@x
    \pgf@xa=4\pgf@y%
    \ifdim\pgf@yc<\pgf@ya%
      \pgf@y=\pgf@ya%
    \fi%
    \ifdim\pgf@xc<\pgf@xa%
      \pgf@x=\pgf@xa%
    \fi%

此外，我同意percusse，你应该试着规避 transformcm，因为你严格来说不需要它。

您可以使用：

 \pgftransformshift{\centerpoint}

为您的第一次transformcm和：

 \pgftransformxscale{-1}

这是您的第二个transformcm。

代码由 Altermundus 添加。

我应用了 zeroth（我的主机）给出的注释和代码。首先，我使用 TeX 组来限制某些变换的动作，然后我删除transformcm并使用了更简单的宏\pgftransformshift{\centerpoint}。zeroth\pgftransformxscale{-1}给了我保持高度和宽度之间良好比例的想法，最后 Jake 的一个很好的回答给了我使用继承形状的最后一个关键。

在下一张图片中我用的是minimum height=8cm

在此处输入图片描述

对于最后一个，对于第一个节点我没有使用任何内容，对于第二个节点我没有使用任何内容minimum width=14cm。

在此处输入图片描述

待办事项：也许验证一些计算来绘制形状。
