package smartclip

import "github.com/paulmach/orb/clip/smartclip"

Package smartclip performs a more advanced clipping algorithm so it can deal with correctly oriented open rings and polygon.

Functions ¶

func Geometry ¶

func Geometry(box orb.Bound, g orb.Geometry, o orb.Orientation) orb.Geometry

Geometry will do a smart more involved clipping and wrapping of the geometry. It will return simple OGC geometries. Rings that are NOT closed AND have an endpoint in the bound will be implicitly closed.

func MultiPolygon ¶

func MultiPolygon(box orb.Bound, mp orb.MultiPolygon, o orb.Orientation) orb.MultiPolygon

MultiPolygon will smart clip a multipolygon to the bound. Rings that are NOT closed AND have an endpoint in the bound will be implicitly closed.

func Polygon ¶

func Polygon(box orb.Bound, p orb.Polygon, o orb.Orientation) orb.MultiPolygon

Polygon will smart clip a polygon to the bound. Rings that are NOT closed AND have an endpoint in the bound will be implicitly closed.

func Ring ¶

func Ring(box orb.Bound, r orb.Ring, o orb.Orientation) orb.MultiPolygon

Ring will smart clip a ring to the boundary. This may result multiple rings so a multipolygon is possible. Rings that are NOT closed AND have an endpoint in the bound will be implicitly closed.
