proj-polyskel

A packaged and maintained version of polyskel for use in Projected projects.

Credits

proj-polyskel is a redistributed and repackaged version of the polyskel library by Ármin Scipiades (@Bottfy), which is a Python implementation of the straight skeleton algorithm as described by Felkel and Obdržálek in their 1998 conference paper "Straight skeleton implementation."

Key differences from the original:

• Packaged for PyPI distribution with modern Python packaging (pyproject.toml)
• Removed test files and development artifacts
• Added proper dependency management
• Maintained for compatibility with Projected toolchain

Installation

pip install proj-polyskel

Quick start

Basic Example

from proj_polyskel import skeletonize

rectangle = [(40, 40), (40, 310), (520, 310), (520, 40)]
skeleton = skeletonize(polygon=rectangle)

Polygon with holes

from proj_polyskel import skeletonize

rectangle = [(40, 40), (40, 310), (520, 310), (520, 40)]
holes = [[(100, 100), (200, 100), (200, 150), (100, 150)]]
skeleton = skeletonize(polygon=rectangle, holes=holes)
