Class PNGEncoder

java.lang.Object
  extended by org.netbeans.jemmy.util.PNGEncoder

public class PNGEncoder
extends java.lang.Object

This class allows to encode BufferedImage into B/W, greyscale or true color PNG image format with maximum compression.
It also provides complete functionality for capturing full screen, part of screen or single component, encoding and saving captured image info PNG file.
