IVertexAttribute2 Interface

additional operations for geometries that can have attributes (z, m, id) on their vertices.

Description

This interface is new at ArcGIS 9.3. It supersedes IVertexAttribute.

Members

	Name	Description
	CalculateNonSimpleVertexAttributes	Extrapolates/interpolates the non-simple vertex attribute values.
	CalculateNonSimpleVertexAttributes2	Extrapolates/interpolates the non-simple vertex attribute values. If useSegmentExtrapolation is true, then the segment immediately incident on those to be extrapolated will be used to determine the extrapolation ratio.
	ExtrapolateVertexAttributes	Extrapolates the attribute values at the begining of the geometry up to the fromIndex based on the attribute value interval between the fromIndex and the toIndex.
	InterpolateVertexAttributesBetween	Generate vertex attribute values by linear interpolation for all vertices in the range [start+1, end-1]. (Sets point IDs to 0 rather than interpolating).
	MultiplyVertexAttributes	Scale all vertex attribute values of this type by the specified factor.
	OffsetVertexAttributes	Offset all vertex attribute values of this type by the specified factor.
	ReplaceVertexAttributes	Replace vertex attributes having the specified value with the new value.
	TransferAttributes	For each vertex on this geometry, assign the attributes found at the point an equal fraction of the distance along the source geometry (the point need not be an explicit vertex).
	VertexAttributeMax	The maximum vertex attribute value of this type for all vertices in this object.
	VertexAttributeMin	The minimum vertex attribute value of this type for all vertices in this object.
	VertexAttributeSimple	Indicates if there are no 'empty' vertex attribute values of this type for this object.

IVertexAttribute2.CalculateNonSimpleVertexAttributes2 Method

Extrapolates/interpolates the non-simple vertex attribute values. If useSegmentExtrapolation is true, then the segment immediately incident on those to be extrapolated will be used to determine the extrapolation ratio.

Public Sub CalculateNonSimpleVertexAttributes2 ( _
    ByVal attributeType As esriGeometryAttributes, _
    ByVal useSegmentExtrapolation As Boolean, _
    ByVal applySingleAtt As Boolean _
)

public void CalculateNonSimpleVertexAttributes2 (
    esriGeometryAttributes attributeType,
    bool useSegmentExtrapolation,
    bool applySingleAtt
);

IVertexAttribute2.ReplaceVertexAttributes Method

Replace vertex attributes having the specified value with the new value.

Public Sub ReplaceVertexAttributes ( _
    ByVal attributeType As esriGeometryAttributes, _
    ByVal oldAtt As Double, _
    ByVal newAtt As Double _
)

public void ReplaceVertexAttributes (
    esriGeometryAttributes attributeType,
    double oldAtt,
    double newAtt
);
