Class OldOffsetCurveBuilder

Namespace

NetTopologySuite.Operation.Buffer

Assembly

NetTopologySuite.dll

Computes the raw offset curve for a single Geometry component (ring, line or point).

Remarks

A raw offset curve line is not noded - it may contain self-intersections (and usually will). The final buffer polygon is computed by forming a topological graph of all the noded raw curves and tracing outside contours. The points in the raw curve are rounded to the required precision model.

Parameters

precisionModel PrecisionModel

bufParams BufferParameters

Methods

GetLineCurve(Coordinate[], double)

This method handles single points as well as lines. Lines are assumed to not be closed (the function will not fail for closed lines, but will generate superfluous line caps).

public IList<Coordinate[]> GetLineCurve(Coordinate[] inputPts, double distance)

Parameters

inputPts Coordinate[]

distance double

Returns

IList<Coordinate[]>

a List of Coordinate[]

GetRingCurve(Coordinate[], Position, double)

This method handles the degenerate cases of single points and lines, as well as rings.

public IList<Coordinate[]> GetRingCurve(Coordinate[] inputPts, Position side, double distance)

Parameters

inputPts Coordinate[]

side Position

distance double

Returns

IList<Coordinate[]>

a List of Coordinate[]

GetRingCurve(Coordinate[], Positions, double)

This method handles the degenerate cases of single points and lines, as well as rings.

[Obsolete("Use GetRingCurve(Coordinate[], Geometries.Position, double)")]
public IList<Coordinate[]> GetRingCurve(Coordinate[] inputPts, Positions side, double distance)

Parameters

inputPts Coordinate[]

side Positions

distance double

Returns

IList<Coordinate[]>

a List of Coordinate[]
