%global _empty_manifest_terminate_build 0 Name: python-visvalingamwyatt Version: 0.2.0 Release: 1 Summary: Simplify geometries with the Visvalingam-Wyatt algorithm License: MIT URL: https://github.com/fitnr/visvalingamwyatt Source0: https://mirrors.nju.edu.cn/pypi/web/packages/6f/f3/feea4fc41bbe6113e6de5836cf255266ce22937bf95445f72d862dda2968/visvalingamwyatt-0.2.0.tar.gz BuildArch: noarch Requires: python3-numpy Requires: python3-coverage %description # Visvalingam-Wyatt A Python implementation of the Visvalingam-Wyatt line simplification algorithm. This implementation is due to [Eliot Hallmark](https://github.com/Permafacture/Py-Visvalingam-Whyatt/). This release simply packages it as a Python module. ## Use ```python >>> import visvalingamwyatt as vw >>> points = [(1, 2), (2, 3), (3, 4), ...] >>> vw.simplify(points) [(1, 2), (3, 4), ...] ``` Points may be any `Sequence`-like object that (`list`, `tuple`, a custom class that exposes an `__iter__` method). Test different methods and thresholds: ```python simplifier = vw.Simplifier(points) # Simplify by percentage of points to keep simplifier.simplify(ratio=0.5) # Simplify by giving number of points to keep simplifier.simplify(number=1000) # Simplify by giving an area threshold (in the units of the data) simplifier.simplify(threshold=0.01) ``` Shorthands for working with geodata: ````python import visvalingamwyatt as vw feature = { "properties": {"foo": "bar"}, "geometry": { "type": "Polygon", "coordinates": [...] } } # returns a copy of the geometry, simplified (keeping 90% of points) vw.simplify_geometry(feature['geometry'], ratio=0.90) # returns a copy of the feature, simplified (using an area threshold) vw.simplify_feature(feature, threshold=0.90) ```` The command line tool `vwsimplify` is available to simplify GeoJSON files: ```` # Simplify using a ratio of points vwsimplify --ratio 0.90 in.geojson -o simple.geojson # Simplify using the number of points to keep vwsimplify --number 1000 in.geojson -o simple.geojson # Simplify using a minimum area vwsimplify --threshold 0.001 in.geojson -o simple.geojson ```` Install [Fiona](https://github.com/Toblerity/Fiona) for the additional ability to simplify any geodata layer. ## License MIT %package -n python3-visvalingamwyatt Summary: Simplify geometries with the Visvalingam-Wyatt algorithm Provides: python-visvalingamwyatt BuildRequires: python3-devel BuildRequires: python3-setuptools BuildRequires: python3-pip %description -n python3-visvalingamwyatt # Visvalingam-Wyatt A Python implementation of the Visvalingam-Wyatt line simplification algorithm.
