IPolygon4 Interface

Provides access to members that extend the IPolygon3 interface.

Members

Name Description
Method Close Closes all rings in this polygon. The resulting polygon may not be simple.
Read-only property ConnectedComponentBag Creates and returns a geometry bag containing polygons that represent connected components of the original. The rings of the output polygons are references to rings in the original.
Method Densify Converts this polycurve into a piecewise linear approximation of itself.
Read-only property Dimension The topological dimension of this geometry.
Read-only property Envelope Creates a copy of this geometry's envelope and returns it.
Read-only property ExteriorRingBag Creates and returns a geometry bag that contains references to all exterior rings.
Read-only property ExteriorRingCount The number of exterior rings.
Method FindExteriorRing Returns the exterior ring containing the specified interior ring.
Read/write property FromPoint The 'from' point of the curve.
Method Generalize Generalizes this polycurve using the Douglas-Peucker algorithm.
Read-only property GeometryType The type of this geometry.
Method GeoNormalize Shifts longitudes, if need be, into a continuous range of 360 degrees.
Method GeoNormalizeFromLongitude Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.
Method GetConnectedComponents Populates an array with polygons that represent connected components of the original. The rings of the output polygons are references to rings in the original.
Method GetOutermostComponents Populates an array with polygons that represent outermost components of the original and all components within (islands within lakes). The rings of the output polygons are references to rings in the original.
Method GetSubcurve Extracts a portion of this curve into a new curve.
Read-only property InteriorRingBag Creates and returns a geometry bag that contains references to all rings that are interior to the specified exterior ring.
Read-only property InteriorRingCount The number of rings interior to the specified exterior ring.
Read-only property IsClosed Indicates if 'from' and 'to' points (of each part) are identical.
Read-only property IsEmpty Indicates whether this geometry contains any points.
Read-only property Length The length of the curve.
Read-only property OutermostComponentBag Creates and returns a geometry bag containing polygons that represent outermost components of the original and all components within (islands within lakes). The rings of the output polygons are references to rings in the original.
Method Project Projects this geometry into a new spatial reference.
Method QueryEnvelope Copies this geometry's envelope properties into the specified envelope.
Method QueryExteriorRings Populates an array with references to all exterior rings. This method does not marshall correctly out-of-proc. Use QueryExteriorRingsEx on the IPolygon2 interface instead.
Method QueryExteriorRingsEx Returns an array of references to exterior rings, up to a maximum of the number requested.
Method QueryFromPoint Copies this curve's 'from' point to the input point.
Method QueryInteriorRings Populates an array with references to rings that are interior to the specified exterior ring. This method does not marshall correctly out-of-proc. Use QueryInteriorRingsEx on the IPolygon2 interface instead.
Method QueryInteriorRingsEx Returns an array of references to rings that are interior to the specified exterior ring, up to a maximum of the number requested.
Method QueryNormal Constructs a line normal to a curve from a point at a specified distance along the curve.
Method QueryPoint Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve.
Method QueryPointAndDistance Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items.
Method QueryTangent Constructs a line tangent to a curve from a point at a specified distance along the curve.
Method QueryToPoint Copies the curve's 'to' point into the input point.
Method ReverseOrientation Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc).
Method SetEmpty Removes all points from this geometry.
Method SimplifyEx Same as ITopologicalOperator::Simplify, but with some additional options that affect performance and how the interior is classified.
Method SimplifyPreserveFromTo Simplifies the polygon and maintains the index location of the from/to point of each ring.
Method SimplifySpaghetti Simplifies a polygon but doesn't assume that rings need to be explicitly closed.
Method Smooth Converts this curve into a smooth curve containing only Bezier curve segments.
Method SnapToSpatialReference Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.
Read/write property SpatialReference The spatial reference associated with this geometry.
Method SplitAtDistance Introduces a new vertex into this polyline at a specified distance from the beginning of the polyline.
Method SplitAtPoint Introduces a new vertex into this polyline at the location on it closest to the input point.
Read/write property ToPoint The 'to' point of the curve.
Method Weed Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.
