Detailed Description

Defines a YIQ color as used in NTSC.

    Y defines the luminance, for a black-and-white image.
    I and Q determine the color.

    Form name: yiq
    Slots:
       1. Y  (Number)  Y component (0.0 to 1.0)
       2. I  (Number)  I component (-0.6 to 0.6)
       3. Q  (Number)  Q component (-0.52.0 to 0.52)

    Events: None  
    Note:  The operators osg::Vec3*() and osg::Vec4*(), (inherited from LcColor)
           return a const pointer to the RGBA color vector and not the
           YIQ color vector.
