  • <DRM HSV Colour Control Link>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class specifies a specialized <DRM Control Link> instance used to provide the connection between an ordered aggregation of <DRM Expression> instances and the target fields of one or more <DRM HSV Colour> instances.

The value of the hue_expression_index field specifies which <DRM Expression> component, if any, controls the hsv_data. hue field value of the affected <DRM HSV Colour> instances. If the value is zero, the hsv_data. hue field of those instances is not controlled; otherwise, the value is a 1-based index into the ordered aggregation of <DRM Expression> instances.

The value of the saturation_expression_index field specifies which <DRM Expression> component, if any, controls the hsv_data. saturation field value of the affected <DRM HSV Colour> instances. If the value is zero, the hsv_data. saturation field of those instances is not controlled; otherwise, the value is a 1-based index into the ordered aggregation of <DRM Expression> instances.

The value of the value_expression_index field specifies which <DRM Expression> component, if any, controls the hsv_data. value field value of the affected <DRM HSV Colour> instances. If the value is zero, the hsv_data. value field of those instances is not controlled; otherwise, the value is a 1-based index into the ordered aggregation of <DRM Expression> instances.
