Usage
>>> from martinez.contour import Contour
>>> from martinez.point import Point
>>> from martinez.polygon import Polygon
>>> left_polygon = Polygon([Contour([Point(0.0, 0.0), Point(2.0, 0.0), Point(2.0, 2.0), Point(0.0, 2.0)], [], True)])
>>> right_polygon = Polygon([Contour([Point(1.0, 1.0), Point(3.0, 1.0), Point(3.0, 3.0), Point(1.0, 3.0)], [], True)])
>>> from martinez.boolean import OperationType, compute
>>> compute(left_polygon, right_polygon, OperationType.INTERSECTION)
Polygon([Contour([Point(1.0, 1.0), Point(2.0, 1.0), Point(2.0, 2.0), Point(1.0, 2.0)], [], True)])
>>> compute(left_polygon, right_polygon, OperationType.UNION)
Polygon([Contour([Point(0.0, 0.0), Point(2.0, 0.0), Point(2.0, 1.0), Point(3.0, 1.0), Point(3.0, 3.0), Point(1.0, 3.0), Point(1.0, 2.0), Point(0.0, 2.0)], [], True)])
>>> compute(left_polygon, right_polygon, OperationType.DIFFERENCE)
Polygon([Contour([Point(0.0, 0.0), Point(2.0, 0.0), Point(2.0, 1.0), Point(1.0, 1.0), Point(1.0, 2.0), Point(0.0, 2.0)], [], True)])
>>> compute(left_polygon, right_polygon, OperationType.XOR)
Polygon([Contour([Point(0.0, 0.0), Point(2.0, 0.0), Point(2.0, 1.0), Point(1.0, 1.0), Point(1.0, 2.0), Point(0.0, 2.0)], [], True), Contour([Point(1.0, 2.0), Point(2.0, 2.0), Point(2.0, 1.0), Point(3.0, 1.0), Point(3.0, 3.0), Point(1.0, 3.0)], [], True)])
original C++ implementation can be invoked by importing from _martinez module instead.
Development
Bumping version
Preparation
Install bump2version.
Pre-release
Choose which version number category to bump following semver specification.
Test bumping version
bump2version --dry-run --verbose $CATEGORY
where $CATEGORY is the target version number category name, possible
values are patch/minor/major.
Bump version
bump2version --verbose $CATEGORY
This will set version to major.minor.patch-alpha.
Release
Test bumping version
bump2version --dry-run --verbose release
Bump version
bump2version --verbose release
This will set version to major.minor.patch.
Running tests
Install dependencies
python -m pip install --force-reinstall -r requirements-tests.txt
