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

		Description
	Densify	Densify segment into the specified number of smaller segments. This method is intended for internal use only.
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	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 This method is obsolete.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 This method is obsolete.
	GetSubcurve	Extracts a portion of this curve into a new curve.
	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.
	Project	Projects this geometry into a new spatial reference.
	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.
	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.
	SplitDivideLength	Divide segment into smaller segments of the specified length.
	ToPoint	The 'to' point of the curve.

Inherited Interfaces

Interfaces	Description
ICurve	Provides access to properties and methods of all 1 dimensional curves (polylines, segments, boundaries of polygons, etc.).
IGeometry	Provides access to members that describe properties and behavior of all geometric objects.

CoClasses that implement ISegment

CoClasses and Classes	Description
BezierCurve	A cubic Bezier curve defined between two points; optionally has measure, height and ID attributes at each endpoint.
CircularArc	A portion of a circle that connects two points optionally has measure, height and ID attributes at each endpoint.
EllipticArc	A portion of the boundary of a 2D ellipse that connects two points; optionally has measure, height and ID attributes at each endpoint.
Line	A 2D straight line between a pair of 2D endpoints; can optionally have height, measure and ID attributes at each endpoint.
