Examples of UomRescaleStyleVisitor

org.geotools.styling.visitor.UomRescaleStyleVisitor

Visitor used for rescaling a Style given a map scale (e.g., meters per pixel) and taking into consideration the Unit of Measure (UOM, e.g., SI.METER, NonSI.FOOT) of each symbolizer. The resulting Style's Symbolizer sizes will all be given in PIXELS, so that they can be directly used by a renderer that is unaware of units of measure or the current map scale. For example, points with size == 100 meters could be rescaled to 10 pixels for higher levels of zoom and 2 pixels for a lower level of zoom.

This visitor extends {@link DuplicatingStyleVisitor} and as such yields a copy of the originalStyle. Usage is simply to call the desired visit() method and then call getCopy() to retrieve the result. @author milton @author Andrea Aime - GeoSolutions @source $URL$
