Provides access to members that extend the functionality of one dimensional curves.

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

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 This method is obsolete.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. | |

QueryPointsAndDistances | Given an input point, calculates the minimum distance to the geometry and provides an enumerator over all closest points on the geometry, along with additional information. | |

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. |

Interfaces | Description |
---|---|

ICurve2 | Provides access to members that extend the functionality of one dimensional curves. |

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 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. |

Polyline | An ordered collection of paths; optionally has measure, height and ID attributes. |
