Provides access to members that identify a path and define its behavior.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
A Path is a connected, continuous sequence of Segments. Except for the first and last Segments in the Path, each segment shares its FromPoint with the ToPoint of the previous Segment, and shares its ToPoint with the FromPoint of the following Segment.
Members
| 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. |
 |
Generalize | Generalizes this path using the Douglas-Poiker 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 This method is obsolete.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. |
|
QueryChordLengthTangents | Returns tangent vectors (relative to corresponding endpoint) at both sides of a Bezier end point; and whether they have been set by user or by smoothing process. |
|
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). |
|
SetChordLengthTangents | Sets tangent vectors (relative to corresponding endpoint) at both sides of a Bezier end point; if either is Nothing, they will be set by smoothing process. |
|
SetEmpty | Removes all points from this geometry. |
|
Smooth | Converts this path into a smooth approximation of itself that contains only Bezier curve segments. |
|
SmoothLocal | Replaces up to four segments (two on each of the specified vertex index) with bezier curves. |
|
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. |
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 IPath
| CoClasses and Classes | Description |
|---|---|
| Path | A sequence of connected segments. |
| Ring | An area bounded by one, closed sequence of connected segments; optionally has measure, height and ID attributes at each vertex. |
Remarks
The Segments composing the Path do not need to be homogenous in type. A Ring is a Path that starts and ends on the same point and defines an area. Paths are the part types in Polylines.
