Convert SVG to PNG with Python on Windows

Question: Which reproducible process can enable Windows Python users to render a SVG image into PNG?

Many questions/answers (such as Convert SVG to PNG in Python and Server-side SVG to PNG (or some other image format) in python, which are not duplicates for the reasons explained below) explain how to convert a SVG to PNG with Python.

Unfortunately, none of them are ready-to-use for Python + Windows. After more than 20 minutes, and many different attempts, I'm still unable to do it. More details about failing attempts:

Installing cairo on Windows is not straightforward, we have to use Gohlke's binaries Intalling pycairo with Python 3.7 on Windows :
```
pip install pycairo-1.20.0-cp37-cp37m-win_amd64.whl
```
Even once cairo is installed, rsvg (from main answers of Server-side SVG to PNG (or some other image format) in python, Convert SVG to PNG in Python) is not available for Windows:
```
pip install rsvg   # or pyrsvg
> ERROR: No matching distribution found for pyrsvg
```

Solutions with svglib or reportlab don't work out-of-the-box on Python3 + Windows:

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF, renderPM
drawing = svg2rlg("a.svg")
renderPM.drawToFile(drawing, "file.png", fmt="PNG")

Indeed:

AttributeError: 'Image' object has no attribute 'fromstring'

So a solution - specific for Windows - would be helpful.

Solution

From the comments, the solution was to install svglib version 1.0.1 and reportlab 3.5.59.
