Property

Description

Class
  • <DRM CMY Colour>

Superclass

Subclass
  • None.

Definition

An instance of this DRM class specifies the actual cyan, magenta, and yellow data values for a colour defined within the CMY colour model. These values shall be in the range [0,0, 1,0].

NOTE  The CMY colour model is closely related to the RGB colour model. Cyan is the complement of red (cyan = 1,0 - red); magenta, of green (magenta = 1,0 - green); and yellow, of blue (yellow = 1,0 - blue)

The cmy_data field specifies the CMY colour coordinate. For a <DRM CMY Colour> instance with a <DRM CMY Colour Control Link> component, the value of the cmy_data field is obtained from the control link.
