Name 
Description 

Close 
Closes all rings in this polygon. The resulting polygon may not be simple. 

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. 

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 DouglasPeucker 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 This method is obsolete.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. 

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. 

GetSubcurve 
Extracts a portion of this curve into a new curve. 

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. 

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. 

QueryExteriorRings 
Populates an array with references to all exterior rings. This method does not marshall correctly outofproc. Use QueryExteriorRingsEx on the IPolygon2 interface instead. 

QueryExteriorRingsEx 
Returns an array of references to exterior rings, up to a maximum of the number requested. 

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 outofproc. 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. 

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. 

SimplifyPreserveFromTo 
Simplifies the polygon and maintains the index location of the from/to point of each ring. 

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.
