ICurve.GetSubcurve Method

Extracts a portion of this curve into a new curve.

[Visual Basic .NET]
Public Sub GetSubcurve ( _
    ByVal fromDistance As Double, _
    ByVal toDistance As Double, _
    ByVal asRatio As Boolean, _
    ByRef outSubcurve As ICurve _
)

[C#]
public void GetSubcurve (
    double fromDistance,
    double toDistance,
    bool asRatio,
    ref ICurve outSubcurve
);

[C++]
HRESULT GetSubcurve(
  double fromDistance,
  double toDistance,
  VARIANT_BOOL asRatio,
  ICurve** outSubcurve
);

[C++]

Parameters

fromDistance fromDistance is a parameter of type double toDistance toDistance is a parameter of type double asRatio asRatio is a parameter of type VARIANT_BOOL outSubcurve [out]

outSubcurve is a parameter of type ICurve

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Gets the subcurve between the specified points along the original curve and creates a new curve. The elements in the new subcurve are the same type and have the same properties as the elements of the original curve. Which means if:

Input Geometry	Output Geometry
Polygon	Polyline
Polyline	Polyline
Ring	Path
Path	Path
Segment	Segment

If the input geometry is a polygon, you may want to use IRing::GetSubCurveEx which has more capabilities.
