Examples of com.vividsolutions.jts.geom.Envelope

com.vividsolutions.jts.geom.Envelope
Defines a rectangular region of the 2D coordinate plane. It is often used to represent the bounding box of a {@link Geometry}, e.g. the minimum and maximum x and y values of the {@link Coordinate}s.
Note that Envelopes support infinite or half-infinite regions, by using the values of Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY.
When Envelope objects are created or initialized, the supplies extent values are automatically sorted into the correct order. @version 1.7
