IPolyline5 Interface

Provides access to members that extend a polyline object.

Product Availability

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

Description

This interface is new at ArcGIS 9.3. This supersedes IPolyline, IPolyline2, IPolyline3, and IPolyline4.

Members

	Name	Description
	Densify	Converts this polycurve into a piecewise linear approximation of itself.
	Dimension	The topological dimension of this geometry.
	EnumShortestPath	Not implemented.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	FromPoint	The 'from' point of the curve.
	Generalize	Generalizes this polycurve using the Douglas-Peucker algorithm.
	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 This method is obsolete.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.
	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.
	Reshape	Modifies this polyline by replacing some of its segments with some segments from reshapeSource.
	ReshapeEx	If bInterpolateReshaped is true, then new vertices will be interpolated based on vertices from the polyline being reshaped. Otherwise, attributes on the reshaping line will be preserved in the output.
	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.
	SimplifyEx	Use either planar or network simplify regardless of current attribute awareness.
	SimplifyNetwork	Removes zero length segments (zero in 2 dimensions), merges parts at endpoints that only connect to each other, reorients segments that are pointing against the prevailing orientation for a part.
	Smooth	Converts this curve into a smooth curve containing only Bezier curve segments.
	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	Introduces a new vertex into this polyline at a specified distance from the beginning of the polyline.
	SplitAtPoint	Introduces a new vertex into this polyline at the location on it closest to the input point.
	ToPoint	The 'to' point of the curve.
	TouchCut	Cut a polyline at locations where the cutter only touches the polyline, in addition to locations where the cutter crosses it.
	Weed	Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.
