答案1
以下是我根据以下回答得出的结论：页边的手写评论和注释。在那里，我使用了 Teen SPirit 字体，这是一种手写字体（通过\fontfamily{fts}\selectfont）。查看该字体的字形集（第 2 页http://www.tug.dk/FontCatalogue/teenspirit/teenspirit.pdf），手绘线有几种选择（例如，字形 40、47、73、108、124 等）。我选择了字形 47
\handxform然后，我创建了用于旋转和缩放字形的宏，其中垂直比例由一个因子给出，水平比例由所需的长度给出（已编辑以解决缩放限制，以便遵守指定的实际宽度）。宏\handline[<thickness-scale>]{<length>}将字形 47 传递给\handxform，以及用户指定的缩放信息，以及将字形 47 转换为适当高度的水平方面所需的旋转。
以下 MWE 中的所有手绘线都是字形 47 的缩放、旋转版本。
\handstealthleftrightarrow[<thickness-scale>]{<length>}通过将字形 60 及其镜像串联起来，进行编辑以添加到混合中：
已编辑以添加\handbox[<thickness-scale>]{<length>}{<height>}，其通过将 4 串在一起来实现\handline。

讨论
下面有一些关于如何调整“嗖嗖”形状的问题。然而，这掩盖了对这里所做事情的根本误解。我所做的就是获取字体的字形，然后旋转/拉伸/重新旋转/平移/重新拉伸/重新平移它，以达到所需的大小和方向。嗖嗖的形状是由完全按所选的原始字形，在本答案中该字形来自 Teen Spirit 字体。
举个例子，如果我重新定义\handxform不使用 Teen Spirit 字体，并且用指定的字形代替，那么使用一个简单的\rule{1pt}{5pt}：
\newcommand\handxform[7]{%
\raisebox{#1}{\scalebox{4}[#6]{%
\raisebox{#2}{\rotatebox{#3}{\stretchto{\rotatebox{#4}{\rule{1pt}{5pt}}}{.25\dimexpr#7}}}}}}
\rule您将看到结果相应地发生变化，其中新的 swish 由转换后的字形 47 或 60 组成。
因此，如果要采用这种技术，为了获得其他形状，必须从其他字体中找到其他合适的字形。或者，有人可以使用它tikz设计所需的 swish，并将其合并到稍微重新定义的\handxform宏中。
作为一个说明性案例，我甚至可以使用 来\includegraphics作为 swish。理想情况下，它应该是透明的 png，但在这里，我只是截取了此页面顶部的图像，将其保存为 jpeg，尝试删除黑色文本，并将其用作 swish。显然，必须重新设计定义和参数以适应这一点（特别是因为纵横比不同），但结果看起来符合预期：
将图像的大版本保存为后greenswish.jpg，上述代码为：

答案2
这是对您可能做的事情的一个不完整且非常简单的演示，尽管它完全无法满足要求，但仍然相当耗时。
以下代码创建了一个相当简单的pic名为 的brush stroke。它接受一个键值选项列表。下面实现的选项是colour、text和name。
创建pic节点，然后根据 Lazur URH 作品中的描边矢量缩放范围和填充路径https://openclipart.org/detail/211152/brush-stroke-2，使用 Inkscape 提取并导出到 TikZ 代码。我稍微编辑了这段代码，并将填充颜色变成了一个变量，该变量拾取选项colour并使其部分透明。

查看答案这个问题（Alain 的答案只是众多优秀答案之一）介绍了使用 LaTeX 创造难以捉摸的“手工”外观的各种方法。并非所有答案都使用 TikZ，但很多答案都使用 TikZ。
注意Marc van Dongen 的回答显示了pencil draw应用于圆弧的方法。矩形角圆角的问题在于所需的圆弧非常小，这会产生各种复杂性，从而带来无穷无尽的麻烦。
