Fast Stroke Width Transform for Python

This repo contains wrapper for libccv's SWT algorithm for use in Python 3. It's compatible with Linux, macOS and Docker.

For more information, see my blog post: http://zablo.net/blog/post/stroke-width-transform-swt-python-3.9

Usage

from swt_python3 import swt

buffer = open("input.jpg", "rb").read()
swt_result: List[dict] = swt(buffer, len(buffer))
for item in swt_result:
    x, y, width, height = [item[key] for key in ("x", "y", "width", "height")]
    print(x, y, width, height)

See example.py for details.
