Description copied from interface: IProjection

First two parameters must be in meters. This should be changed (map units should be used) and then change the places where this method is used.

Specified by:

getScale in interface IProjection

Parameters:

minX - in meters

maxX - in meters

w - in pixels (dots)

dpi - dots per inch

Description copied from interface: Cloneable

Creates a copy of the object.

Overrides:

clone in class java.lang.Object

Returns:

a copy of the object

Throws:

java.lang.CloneNotSupportedException - if the instance of the object cannot be cloned. As this is extending Cloneable so its sure it implements it, so this exception may be used for problems on specific object instances.
