页边的手写评论和注释

Question

结合我在评论中提到的问题的结果……即 doncherry 使用的fts“Teen Spirit”字体（http://www.tug.dk/FontCatalogue/teenspirit/) 参考自我怎样才能使我的文档看起来像是由崇拜克苏鲁的疯子写的？。我也用我的答案有哪些方法可以将内容绝对定位在页面上？（适用于新挂钩系统）

下面我来介绍一下

\handnote[<angle>]{<x from left>}{<y from top>}{<width>}{<color>}{<content>}

编辑后引入以下支持重点标记：

\handline[<thickness-scale>]{<width>}
\handrightarrow[<thickness-scale>]{<width>}
\handleftarrow[<thickness-scale>]{<width>}
\handhookrightarrow[<thickness-scale>]{<width>}
\handhookleftarrow[<thickness-scale>]{<width>}
\handstealthrightarrow[<thickness-scale>]{<width>}
\handstealthleftarrow[<thickness-scale>]{<width>}
\handuparrow[<thickness-scale>]{<height>}
\handdownarrow[<thickness-scale>]{<height>}

\handnote这些强调标记在的上下文中显示为宏<content>。因此，当它们构成给定的完整内容时，可以使用的参数\handnote自由旋转它们。使用不同的s 和s 可以避免重复强调标记。<angle>\handnote<thickness-scale><width>

还进行了编辑，使得<content>的\handnote现在与由指定的垂直坐标顶部对齐<y from top>。

这是 MWE。重点标记总结在第 2 页（已编辑以说明 2018.12.1 上的 LaTeX 内核更改）：

编辑注释：修改了宏，引入了缩放/反缩放，从而扩展了强制参数（长度）可以成功应用的\handxform尺寸范围。现在可以使用宏来制作长度与长度一样长的线，而不会发生算术溢出。\handline\handline\LARGE 47ex
