Class

• <DRM RGB Colour Control Link>

Superclass

• <DRM Control Link>

Subclass

• None.

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 one-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 red field values of the rgb_data field(s) of the target <DRM RGB Colour> instance(s). If the value is zero, the red field of those <DRM RGB Colour> instance(s) is not controlled.

The green_expression_index field is a one-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 green field values of the rgb_data field(s) of the target <DRM RGB Colour> instance(s). If the value is zero, the green field of those <DRM RGB Colour> instance(s) is not controlled.

The blue_expression_index field is a one-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 blue field values of the rgb_data field(s) of the target <DRM RGB Colour> instance(s). If the value is zero, the blue field of those <DRM RGB Colour> instance(s) is not controlled.

Example(s)
