Provides access to members that identify third degree bezier curve segments and defines their properties.
Name Description
Degree The degree of the Bezier curve. For third degree Beziers, this is always 3.
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 This method is obsolete.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.
IsLine Indicates if the curve degenerated to a line.
Length The length of the curve.
Parameter The parametric distance along the bezier.
Project Projects this geometry into a new spatial reference.
PutCoord Sets the specified (0 <= index < 4) control point of this Bezier curve.
PutCoords Sets this Bezier curve's control points from an array of between 1 to 4 input points.
PutWKSCoords Sets this Bezier curve's control points from the array of 4 input point structures.
QueryChordLengthTangentAtFrom Returns tangent vector at 'from' point, based on chord length parametrization; and whether it has been set by user or by smoothing process.
QueryChordLengthTangentAtTo Returns tangent vector at 'to' point, based on chord length parametrization; and whether it has been set by user or by smoothing process.
QueryCoord Copies the specified control point of this Bezier curve into the input point.
QueryCoords Copies this Bezier curve's control points into the array of 4 existing points.
QueryEnvelope Copies this geometry's envelope properties into the specified envelope.
QueryFromPoint Copies this curve's 'from' point to the input point.
QueryInflectionPoint Finds inflection point; sets it empty if none exists.
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.
QueryWKSCoords Copies this Bezier curve's control points into the array of 4 existing point structures.
ReverseOrientation Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
SetChordLengthTangentAtFrom Establishes tangent vector at 'from' point, based on chord length parametrization; and sets flag whether it has been set by user or by smoothing process.
SetChordLengthTangentAtTo Establishes tangent vector at 'to' point, based on chord length parametrization; and sets flag whether it has been set by user or by smoothing process.
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.
The parametric distance along the bezier.
