Class ImageGeometry

Object

ImageGeometry

All Implemented Interfaces:

Serializable, Cloneable, GridGeometry

public class ImageGeometry
extends Object
implements GridGeometry, Serializable, Cloneable

A simple grid geometry holding the grid range as a rectangle and the grid to CRS relationship as an affine transform. This grid geometry does not hold any Coordinate Reference System information. Because of that, it is not suitable to GridCoverage2D (the later rather use GridGeometry2D). But it is sometime used with plain rendered image instances.

Constructor Detail

ImageGeometry

public ImageGeometry(Rectangle bounds,
                     AffineTransform gridToCRS)

Creates a grid geometry from the specified bounds and grid to CRS affine transform.

Parameters:

bounds - The image bounds in pixel coordinates.

gridToCRS - The affine transform from pixel coordinates to "real world" coordinates.

Method Detail

getGridRange

public GridEnvelope2D getGridRange()

Returns the image bounds in pixel coordinates.

Specified by:

getGridRange in interface GridGeometry

Returns:

The valid coordinate range of a grid coverage.

getGridToCRS

public AffineTransform2D getGridToCRS()

Returns the conversion from grid coordinates to real world earth coordinates.

Specified by:

getGridToCRS in interface GridGeometry

Returns:

The conversion from grid coordinates to real world earth coordinates.

toString

public String toString()

Returns a string representation of this grid geometry. The returned string is implementation dependent. It is usually provided for debugging purposes.

Overrides:

toString in class Object

hashCode

public int hashCode()

Returns a hash code value for this grid geometry.

Overrides:

hashCode in class Object

equals

public boolean equals(Object object)

Compares this grid geometry with the specified one for equality.

Overrides:

equals in class Object

Parameters:

object - The object to compare with.

Returns:

true if the given object is equals to this grid geometry.

clone

public ImageGeometry clone()

Returns a clone of this image geometry.

Overrides:

clone in class Object

Returns:

A clone of this grid geometry.
