public final class Envelope
extends Geometry

A geometry that represents a rectangular shape.

An Envelope is an axis-aligned box described by the coordinates of the lower left corner and the coordinates of the upper right corner. They are commonly used to represent the spatial extent covered by layers or other geometries, or to define an area of interest. They can be used as the geometry for a graphic and as an input for many spatial operations. Although they both represent a geographic area, an Envelope is distinct from a Polygon, and they cannot always be used interchangeably.

New instances of Envelope are defined by specifying minimum and maximum x coordinates and minimum and maximum y coordinates, and a SpatialReference. Optionally, a minimum and maximum z value can be specified to define the depth of the envelope.

The sides of an Envelope align with the axes of its SpatialReference. If the SpatialReference is a geographic coordinate system, the x coordinates relate to lines of longitude and the y coordinates relate to lines of latitude.

Envelope is immutable. Instead of changing the properties of an existing Envelope, create new Envelope instances, or use EnvelopeBuilder.

Envelopes cannot be used as the Geometry of a Feature.

If the Envelope is empty, then getXMin(), getXMax(), getYMin(), getYMax(), getZMin(), getZMax(), getMMin(), getMMax(), getWidth(), getHeight(), and getCenter() will all return NaN.
