Class SharpenImageProcessor

java.lang.Object

org.openstreetmap.josm.gui.layer.imagery.SharpenImageProcessor

All Implemented Interfaces:

SessionAwareReadApply, ImageProcessor

public class SharpenImageProcessor
extends java.lang.Object
implements ImageProcessor, SessionAwareReadApply

Sharpens or blurs the image, depending on the sharpen value.

A positive sharpen level means that we sharpen the image.

A negative sharpen level let's us blur the image. -1 is the most useful value there.
