IGeCurve.OffsetCurve Method

IGeCurveOffsetCurve Method

Returns offset geometry of this curve.

Namespace: FDF.Common.Geometries
Assembly: FDF.Common (in FDF.Common.dll) Version: 3.0.0.0

Syntax

IGeGeometry OffsetCurve(
	GeLength distance
)

Function OffsetCurve ( 
	distance As GeLength
) As IGeGeometry

IGeGeometry^ OffsetCurve(
	GeLength^ distance
)

abstract OffsetCurve : 
        distance : GeLength -> IGeGeometry

Parameters

distance: Type: FDF.Common.GeometriesGeLength

Return Value

Type: IGeGeometry

Remarks

The positive direction of offset at a point on the curve is taken to be the right-handed normal to the tangent vector at that point. So if the tangent vector at a point on the curve is (x,y), the positive direction of offset will be (-y,x). The curve may be offset in either of two directions by specifying a positive or negative offset distance.
