Convert PNG to SVG using python

Question

Is there way to convert a png file into SVG file using only pure python or a python module such as wand?

To be more precise, I want to convert a png into a real vector graphics, I don't want to embed a bitmap inside the svg, I want to convert into graphics code.

I know this is possible with Illustrator or Inkscape, but I need an automated process.

Thank you !

Answer 1

You will need to run an external program to do the image tracing. A popular program is potrace. It is what Inkscape uses to perform the task.

There are some python bindings for it:

Answer 2

I would suggest using potrace for python.
Use this link: https://pypi.org/project/pypotrace/
Here is the documentation: https://pythonhosted.org/pypotrace/ref.html#

Like This:

from potrace import Bitmap

# Initialize data, for example convert a PIL image to a numpy array
# [...]

bitmap = Bitmap(data)
path = bitmap.trace()
