IPolyline3 Interface

Provides access to members that extend a polyline object.

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 This method is obsolete.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. | |

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. | |

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. |
