cxregions

This package is a Python interface to the ComplexRegions.jl Julia package, providing tools for working with complex regions defined by paths and curves. It allows users to create, manipulate, and analyze geometric shapes such as circular polygons and general polygons using Julia's computational capabilities from within Python.

Installation

To install the cxregions package, you can use pip:

pip install cxregions

The first time you import cxregions, it will set up a Julia environment and install the necessary Julia packages. This may take a few minutes.

Usage

Here is a simple example of how to use the cxregions package:

from cxregions import Polygon, Line, Arc, Mobius

# Create curves
line1 = Line(0+0j, 2+2j)
print(line1.point(0.5))  # Should print 1+1j
arc1 = Arc(-1j, 1j, -1)
p = Polygon([4, 4 + 3j, 3j, -2j, 6 - 2j, 6])
print(p.winding(5 - 1j)) # Should print 1

# Möbius transformation
f = Mobius(1, 1, 1, -1) # f(z) = (z+1)/(z-1)
print(f(0)) # -1.0
print(f(line1)) # A Circle
