Class VariableBuffer

Namespace

NetTopologySuite.Operation.Buffer

Assembly

NetTopologySuite.dll

Creates a buffer polygon with a varying buffer distance at each vertex along a line.

Only single lines are supported as input, since buffer widths generally need to be specified individually for each line.

Constructors

VariableBuffer(Geometry, double[])

Creates a generator for a variable-distance line buffer.

public VariableBuffer(Geometry line, double[] distance)

Parameters

line Geometry

The linestring to buffer

distance double[]

The buffer distance for each vertex of the line

Methods

Buffer(Geometry, double, double)

Creates a buffer polygon along a line with the buffer distance interpolated between a start distance and an end distance.

public static Geometry Buffer(Geometry line, double startDistance, double endDistance)

Parameters

line Geometry

The line to buffer

startDistance double

The buffer width at the start of the line

endDistance double

The buffer width at the end of the line

Returns

Geometry

The variable-distance buffer polygon

Buffer(Geometry, double, double, double)

Creates a buffer polygon along a line with the buffer distance interpolated between a start distance, a middle distance and an end distance. The middle distance is attained at the vertex at or just past the half-length of the line. For smooth buffering of a LinearRing (or the rings of a Polygon) the start distance and end distance should be equal.

public static Geometry Buffer(Geometry line, double startDistance, double midDistance, double endDistance)

Parameters

line Geometry

The line to buffer

startDistance double

The buffer width at the start of the line

midDistance double

The buffer width at the middle vertex of the line

endDistance double

The buffer width at the end of the line

Returns

Geometry

The variable-distance buffer polygon

Buffer(Geometry, double[])

Creates a buffer polygon along a line with the distance specified at each vertex.

public static Geometry Buffer(Geometry line, double[] distance)

Parameters

line Geometry

The line to buffer

distance double[]

The buffer distance for each vertex of the line

Returns

Geometry

The variable-width buffer polygon

GetResult()

Computes the buffer polygon.

public Geometry GetResult()

Returns

Geometry

A buffer polygon
