Boolean operations and overlap removal for curves

shapeops-py

A Python port of the caryll-shapeops Javascript library to perform boolean operations and overlap removal on Bezier curves.

The shapeops.ufo module provides the same interface as the BooleanOperations package, with the four union, intersections, difference and xor operations, and support for the PointPen protocol.

Usage

TODO

import shapeops
shape1 = [[
  {'x': 0, 'y': 0, 'on': True},
  {'x': 100, 'y': 0, 'on': False},
  {'x': 200, 'y': 100, 'on': False},
  {'x': 200, 'y': 200, 'on': True},
  {'x': 0, 'y': 0, 'on': True}
], ...]
shape2 = [...]
result = shapeops.boole(shapeops.ops.intersection, shape1, shape2)
