ArcObjects Library Reference (Geometry)

IEnvelope Interface

Provides access to methods and properties of envelopes. Note: the IEnvelope interface has been superseded byIEnvelope2. Please consider using the more recent version.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Envelopes are the rectangular window that contain a specific element. All Geometry objects have an envelope defined by the XMin, XMax, YMin, and YMax of the object. Envelopes can also serve as the viewing area for a particular view screen or data frame.

Members

	Name	Description
	CenterAt	Moves this envelope so it is centered at p.
	DefineFromPoints	Defines the envelope to cover all the points.
	DefineFromWKSPoints	Defines the envelope to cover all the points.
	Depth	The depth of the envelope.
	Dimension	The topological dimension of this geometry.
	Envelope	Creates a copy of this geometry's envelope and returns it.
	Expand	Moves the X and Y coordinates of the sides toward or away from each other.
	ExpandM	Moves the measure of the sides toward or away from each other.
	ExpandZ	Moves the Z attribute of the sides toward or away from each other.
	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 This method is obsolete.
	Height	The height of the envelope.
	Height	The height of the envelope.
	Intersect	Adjusts to include only the area also included by inEnvelope.
	IsEmpty	Indicates whether this geometry contains any points.
	LowerLeft	The lower left corner.
	LowerRight	The lower right corner.
	MinMaxAttributes	A reference to the attribute structures for this envelope.
	MMax	The maximum measure value in the area of the envelope.
	MMin	The minimum measure value in the area of the envelope.
	Offset	Moves the sides x units horizontally and y units vertically.
	OffsetM	Moves the sides m units.
	OffsetZ	Moves the sides z units.
	Project	Projects this geometry into a new spatial reference.
	PutCoords	Constructs an envelope from the coordinate values of lower, left and upper, right corners.
	PutWKSCoords	Copies e's dimensions into this envelope.
	QueryCoords	Returns the coordinates of lower, left and upper, right corners.
	QueryEnvelope	Copies this geometry's envelope properties into the specified envelope.
	QueryWKSCoords	Copies the left, bottom, right and top sides into e.
	SetEmpty	Removes all points from this geometry.
	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.
	Union	Adjusts to overlap inEnvelope.
	UpperLeft	The upper left corner.
	UpperRight	The upper right corner.
	Width	The width of the envelope.
	XMax	The position of the right side.
	XMin	The position of the left side.
	YMax	The position of the top.
	YMin	The position of the bottom.
	ZMax	The maximum Z value in the area of the envelope.
	ZMin	The minimum Z value in the area of the envelope.

Inherited Interfaces

Interfaces	Description
IGeometry	Provides access to members that describe properties and behavior of all geometric objects.

CoClasses that implement IEnvelope

CoClasses and Classes	Description
Envelope	A rectangle with sides parallel to a coordinate system defining the extent of another geometry; optionally has min and max measure, height and ID attributes.

[C#]

//The following C# code shows how to create an envelope from coordinates:
IEnvelope env=new EnvelopeClass() as IEnvelope;

env.PutCoords(-10, -5, 10, 5);
