Provides access to members that extend the functionality of one dimensional curves. Note: the ICurve2 interface has been superseded byICurve3 . Please consider using the more recent version.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
ICurve2 extends Segment functionality to allow both endpoints to be set simultaneously. This allows the segment parameterization to be maintained when relocating both the From Point and the To Point .
Members
All Properties Methods Inherited Non-inherited Description
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.
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 This method is obsolete.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.
PutCoordsEx Sets this segment's endpoints to 'from' and 'to'.
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.
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.
ToPoint The 'to' point of the curve.
