ArcObjects Library Reference (Geometry)

ISegment Interface

Provides access to members that identify a segment. A segment is a way of getting between two endpoints.

Product Availability

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

Members

	Name	Description

	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	EnvelopeIntersection	Finds intersections with clipping envelope; boundaryOverlap is ignored for non-linear segments.
	FromPoint	The 'from' point of the curve.
	GeographicShift	Shift longitudes to the right of splitLongitude. This method is obsolete.
	GeometryType	The type of this geometry.
	GeoNormalize	Shifts longitudes, if need be, into a continuous range of 360 degrees.
	GeoNormalizeFromLongitude	Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
	GetDistanceAtVertexAttribute	Gets the distance corresponding to the attribute value along the segment.
	GetPointsAtVertexAttribute	Gets the point at the location corresponding to the attribute value.
	GetSubcurve	Extracts a portion of this curve into a new curve.
	GetSubSegmentBetweenVertexAttributes	Gets the segment corresponding to the extent along the segment between the 'from' and 'to' attribute values.
	GetVertexAttributeAtDistance	Gets the attribute value corresponding to the distance along the segment.
	HasVertexAttributes	Returns two booleans telling if the segment as from attribute and to attribute values.
	HorizontalIntersectionCount	Returns the number of horizontal intersections.
	InterpolateVertexAttributes	Interpolates Z and M values at distanceAlongSegment and stores the results at point.
	IsClosed	Indicates if 'from' and 'to' points (of each part) are identical.
	IsEmpty	Indicates whether this geometry contains any points.
	Length	The length of the curve.
	MaxDistanceFromLine	Returns the maximum distance from the line.
	Project	Projects this geometry into a new spatial reference.
	PutAttributes	Sets some attributes from this point and copies them to another point. Awareness is not considered.
	PutVertexAttributes	Sets the 'from' and the 'to' attribute values.
	QueryAreaCorrection	Queries the area correction value.
	QueryAttributes	Gets some attributes from this point and copies them to another point. Awareness is not considered.
	QueryCentroidCorrection	Queries the centroid correction value.
	QueryCurvature	Finds curvature and unit vector starting at point on segment and directed to embedded circle center.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	QueryFromPoint	Copies this curve's 'from' point to the input point.
	QueryNormal	Constructs a line normal to a curve from a point at a specified distance along the curve.
	QueryPoint	Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve.
	QueryPointAndDistance	Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.
	QueryTangent	Constructs a line tangent to a curve from a point at a specified distance along the curve.
	QueryToPoint	Copies the curve's 'to' point into the input point.
	QueryVertexAttributes	Gets the 'from' and the 'to' attribute values.
	QueryWKSEnvelope	Queries the WKS Envelope.
	QueryWKSFromPoint	Query the WKSPoint at the 'from' point.
	QueryWKSToPoint	Query the WKSPoint at the 'to' point.
	ReturnTurnDirection	Finds turn direction between two connected segments.
	ReverseOrientation	Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
	SetEmpty	Removes all points from this geometry.
	SnapToSpatialReference	Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
	SpatialReference	The spatial reference associated with this geometry.
	SplitAtDistance	Split segment at specified distance.
	SplitAtVertexAttribute	Splits the segment in two segments at the location corresponding to the attribute value.
	SplitDivideLength	Divide segment into smaller segments of the specified length.
	SynchronizeEmptyAttributes	Synchronize Empty Attributes.
	ToPoint	The 'to' point of the curve.
	VertexAttributeAware	Indicates if the segment is aware of the specified attribute type.
	VertexAttributeOn	Indicates if attributeValue is located on this segment.
