ISurfaceOp.ContourAsPolyline Method

Creates a single contour or isoline that passes through a specified point on a surface.

[Visual Basic .NET]
Public Sub ContourAsPolyline ( _
    ByVal GeoDataset As IGeoDataset, _
    ByVal inputPoint As IPoint, _
    ByRef contourLine As IPolyline, _
    ByRef elevation As Double _
)

[C#]
public void ContourAsPolyline (
    IGeoDataset GeoDataset,
    IPoint inputPoint,
    ref IPolyline contourLine,
    ref double elevation
);

[C++]
HRESULT ContourAsPolyline(
  IGeoDataset* GeoDataset,
  IPoint* inputPoint,
  IPolyline** contourLine,
  double* elevation
);

[C++]

Parameters
GeoDataset [in]

  GeoDataset is a parameter of type IGeoDataset
inputPoint [in]

  inputPoint is a parameter of type IPoint
contourLine [out]

  contourLine is a parameter of type IPolyline
elevation [out]
  elevation is a parameter of type double

Product Availability

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

Remarks

GeoDataset	an input Raster, RasterDataset, RasterBand, or RasterDescriptor to be contoured
inputPoint	an input point feature defined by a point object using IPoint interface which the resulting contour or isoline will pass through
contourLine	the output contour or isoline polyline object which represents the constant cell values of the input point.
elevation	an output double value which represents the cell value that the input point intersects with in the input GeoDataset. This value therefore can be used to describe the value of the output contour line
