Provides additional operations on polygons.

Members

	Name	Description
	Close	Closes all rings in this polygon. The resulting polygon may not be simple.
	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.
	Densify	Converts this polycurve into a piecewise linear approximation of itself.
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	ExteriorRingBag	Creates and returns a geometry bag that contains references to all exterior rings.
	ExteriorRingCount	The number of exterior rings.
	FindExteriorRing	Returns the exterior ring containing the specified interior ring.
	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 This method is obsolete.
	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.
	GetConnectedComponents2	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.
	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.
	GetOutermostComponents2	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.
	GetSubcurve	Extracts a portion of this curve into a new curve.
	InteriorRingBag	Creates and returns a geometry bag that contains references to all rings that are interior to the specified exterior ring.
	InteriorRingCount	The number of rings interior to the specified exterior ring.
	IsClosed	Indicates if 'from' and 'to' points (of each part) are identical.
	IsEmpty	Indicates whether this geometry contains any points.
	IsEnvelope	Returns true if the shape of this polygon is equivalent to the polygon's bounding envelope.
	Length	The length of the curve.
	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.
	Project	Projects this geometry into a new spatial reference.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	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.
	QueryExteriorRingsEx	Returns an array of references to exterior rings, up to a maximum of the number requested.
	QueryExteriorRingsEx2	Returns an array of references to exterior rings.
	QueryFromPoint	Copies this curve's 'from' point to the input point.
	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.
	QueryInteriorRingsEx	Returns an array of references to rings that are interior to the specified exterior ring, up to a maximum of the number requested.
	QueryInteriorRingsEx2	Returns an array of references to rings that are interior to the specified exterior ring, up to a maximum of the number requested.
	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).
	SetEmpty	Removes all points from this geometry.
	SimplifyEx	Same as ITopologicalOperator::Simplify, but with some additional options that affect performance and how the interior is classified.
	SimplifyPreserveFromTo	Simplifies the polygon and maintains the index location of the from/to point of each ring.
	SimplifySpaghetti	Simplifies a polygon but doesn't assume that rings need to be explicitly closed.
	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.
	Weed	Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.

IPolygon5.IsEnvelope Property

Returns true if the shape of this polygon is equivalent to the polygon's bounding envelope.
