IPoint Interface

Provides access to members that define two dimensional points.

Description

A Point is a zero-dimensional object that represents a specific (X, Y) location in a the two-dimensional XY-Plane.  A Point may also have Z, M, and ID attributes associated with it.  Existence of attributes does not alter the dimensionality of a Point nor does it alter geometric calculations performed on the Point.  Attributes are only considered for attribute calculations when the Point is ZAware, MAware, or PointIDAware.  Points may be constructed using PutCoords, individually setting the X and Y properties, or using the IConstructPoint interface.

Members

Name Description
Method Compare Compares X, Y, M, Z, ID of this point (in that order) with that of the other point. Returns -1 if this point's value is less, 1 if greater, and 0 otherwise. Useful for sorting a group of points.
Method ConstrainAngle Projects this point to the point on the infinite line defined by anchor and angle (in radians). If allowOpposite is true, then the point can also snap to angle + pi radians.
Method ConstrainDistance Projects this point to the perimeter of the circle defined by radius and anchor.
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 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 This method is obsolete.
Read/write property ID The Point ID attribute.
Read-only property IsEmpty Indicates whether this geometry contains any points.
Read/write property M The measure attribute.
Method Project Projects this geometry into a new spatial reference.
Method PutCoords Sets the X and Y coordinates.
Method QueryCoords Returns the X and Y coordinates.
Method QueryEnvelope Copies this geometry's envelope properties into the specified envelope.
Method SetEmpty Removes all points from this geometry.
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.
Read/write property VertexAttribute Any attribute (coordinate), except X or Y.
Read/write property X The X coordinate.
Read/write property Y The Y coordinate.
Read/write property Z The Z attribute.
