Definition

An instance of this DRM class is 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 RGB Colour> instances.

The red_expression_index field is a 1-based index into the ordered aggregation of <DRM Expression> instances, and is used to select the specific <DRM Expression> instance (if any) that controls the target <DRM RGB Colour> instances’ rgb_data.red field values. If the value is zero, the rgb_data. redfield of those instances is not controlled.

The green_expression_index field is a 1-based index into the ordered aggregation of <DRM Expression> instances, and is used to select the specific <DRM Expression> instance (if any) that controls the target <DRM RGB Colour> instances’ rgb_data.green field values. If the value is zero, the rgb_data. greenfield of those instances is not controlled.

The blue_expression_index field is a 1-based index into the ordered aggregation of <DRM Expression> instances, and is used to select the specific <DRM Expression> instance (if any) that controls the target <DRM RGB Colour> instances’ rgb_data.blue field values. If the value is zero, the rgb_data. bluefield of those instances is not controlled.
