Parameters

geometries

Specifies the input geometries.

distances

The distances to buffer the geometries. If there are less distances than geometries, the last distance value is used for the remaining geometries.

distanceUnit

The unit of the buffer distance. If null, then the buffer distance is in meters.

maxDeviation

The deviation in meters to use for convergence. The geodetic arcs of the resulting buffer will be closer than the max deviation of the true buffer. Pass in NaN or a value less than or equal to 0 to use the default deviation which will be the maximum of 0.01 meters and 0.2% of the buffer distance.

curveType

The GeodeticCurveType of the segments. If the curveType is GeodeticCurveType::ShapePreserving, then the segments are densified in the spatial reference where they are defined before buffering.

unionResult

Signifies whether the buffered geometries will be unioned or not.

Return Value

If the buffer distance is zero and the input geometry is a polygon or an envelope, then a polygon created from the input geometry is returned. If the buffer distance is zero and the input geometry is not a polygon or an envelope, an empty polygon is returned.

A negative buffer distance can be used to create a buffer inside a polygon or an envelope. Using a negative buffer distance shrinks the geometry's boundary by the distance specified. Note that if the absolute value of the negative distance is too large, the buffer may collapse to an empty polygon. If a negative buffer distance is used and the input geometry is not a polygon or an envelope, then an empty polygon is returned.
