Class YCCKColorSpace

java.lang.Object
  java.awt.color.ColorSpace
      com.sun.pdfview.colorspace.YCCKColorSpace

All Implemented Interfaces:

java.io.Serializable

public class YCCKColorSpace
extends java.awt.color.ColorSpace

A ColorSpace for the YCCK color space. This color space converts to CMYK and then uses an existing CMYK color space to convert from CMYK to RGB. This allows embedded CMYK color profiles to be used with YCCK images. If no CMYK color space is provided then by default it uses a CMYKColorSpace. Only toRGB is supported.
