Constructs a new event. If
oldZoom and
newZoom are the affine transforms
before and after the change respectively, then the following relation must hold (within
the limits of rounding error):
newZoom = oldZoom.
AffineTransform.concatenate concatenate (change) Parameters: source - The event source (usually a org.geotools.gui.swing.ZoomPane). Parameters: change - An affine transform indicating the zoom change.
Returns the affine transform indicating the zoom change.
Note: for performance reasons, this method does not clone
the returned transform. Do not change!
