我正在使用 Python 的 svgwrite 库生成这个键盘 SVG。

没有考虑文本大小和文本位置。不考虑相对于字母组的 x 和 y 位置。绝对的字体大小在inkscape中显示得更大。

      <rect fill="black" height="15.0" id="box-Y" stroke="none" stroke-width="0.5" width="12.5" x="0" y="0"/>
      <text style="text-anchor:end;text-align:start;writing-mode:ltr;     font-size:4px; font-family:Bitstream Vera Sans; fill:white" x="2.0" y="5.0">Y</text>
    </g>
  </g>
</svg>

我希望文本大小是以 px 表示的大小。文本相对于组的插入位置必须以无单位表示，因此以 mm 为单位，因为这是使用 viewbox 设置的默认单位。

它的效果并不明显。SVG 节点的height和width值正在整体缩放绘图。

<svg xmlns="http://www.w3.org/2000/svg" xmlns:ev="http://www.w3.org/2001/xml-events" xmlns:xlink="http://www.w3.org/1999/xlink" baseProfile="full" height="297mm" version="1.1" viewBox="0 0 210 297" width="210mm">

观察当你增加和减少font-size每个字母时会发生什么，然后是svg节点的高度和宽度（这里是一个演示）

虽然我确定您在这里寻找的布局是您正在构建的 SVG 的修改版本（不mm作为svg节点大小的单位）并且居中的字体稍大）：（演示）
