Method Detail

envelopeToPolygon

public static Polygon envelopeToPolygon(Envelope env)

Parameters:

env -

Returns:

a polygon

move

public static Geometry move(Geometry geom,
                            double offx,
                            double offy)

Moves the coordinates of a geometry.

Parameters:

geom - use only surfaces, line strings or points, and only with dim == 2

offx -

offy -

Returns:

the moved geometry

prettyPrintShape

createConvertedEnvelope

public static Envelope createConvertedEnvelope(Envelope sourceEnvelope,
                                               CRS targetCRS)
                                        throws TransformationException

Converts the given Envelope into an envelope with the given coordinate system. Basically this is a delegate call to the GeometryTransformer.

Parameters:

sourceEnvelope - to convert

targetCRS -

Returns:

the target Envelope

Throws:

TransformationException

TransformationException - if the transformation between the source and target crs cannot be created.

createEnvelope

public static final float[] createEnvelope(Envelope validDomain)

Creates float array out of an envelope (Geometry).

Parameters:

validDomain -

Returns:

a float[] representation of the given envelope

createEnvelope

public static final Envelope createEnvelope(float[] env,
                                            CRS crs)

Parameters:

env -

crs -

Returns:

reverse of the other createEnvelope method
