Line width in SVGs

[djn-ams]

Inspired by bproc265, I generated a minimal example to test line width in SVG creation.

Here's the relevant code:

\documentclass{amsart}

\usepackage{tikz}

\begin{document}

\begin{tikzpicture}

\foreach \width in {1, ..., 10} {
  \draw[line width = \width pt] (\width - 1,0) -- (\width - 1, 5);
  \node at (\width - 1, 5.25) {\width pt};

  \draw[line width = 0.1 * \width pt] (\width - 1, -1) -- (\width - 1, -6);
  \node at (\width - 1, -6.25) {$\frac{\width}{10}$pt};
}

\end{tikzpicture}

\end{document}

And here's the SVG it generates:

Unlike bproc265, the SVG here looks good to me.

For comparison, here's a rasterization from a PDF rendering of the TeX source where (to my eyes) 2/10pt and 6/10pt look thinner than their smaller counterparts.

This was screenshot when opening the PDF in a browser (i.e., pdfjs). I intentionally chose this zoom level (which happened to be the default on my setup)

@pkra I mostly agree. 1/10pt through about 7/10pt all look the same to me with 2/10pt being marginally thinner. Although, to me, 2/10pt looks noticeably sharper, so I imagine that comes down to the rasterization/rendering of the image.
