Class YCCKColorSpace

java.lang.Object

java.awt.color.ColorSpace

org.openpdf.renderer.colorspace.YCCKColorSpace

All Implemented Interfaces:

Serializable

public class YCCKColorSpace
extends 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.
