Description

Class

  • <DRM Colour Table Group>

Superclass

Subclass

  • None.

Definition

An instance of this DRM class specifies an interchangeable group of one or more <DRM Colour Table> instances. The primary <DRM Colour Table> instance in the group is indicated by the primary_table_index. When a reference is made to a <DRM Colour Table> instance (for example, from a <DRM Colour Index> component of a <DRM Polygon> instance), the reference identifies the <DRM Colour Table Group> instance and the index within the <DRM Colour Table> instance, but not the specific <DRM Colour Table> instance within the <DRM Colour Table Group> instance. By definition, a <DRM Colour Index> instance refers to a <DRM Primitive Colour> instance from the primary <DRM Colour Table> instance of the indicated <DRM Colour Table Group> instance. An alternate <DRM Colour Table> instance from within the <DRM Colour Table Group> instance can be chosen at the discretion of the data consumer.

The primary_table_index field specifies the primary <DRM Colour Table> component of the <DRM Colour Table Group> instance from its ordered <DRM Colour Table> components.

The table_size field specifies the size of all <DRM Colour Table> components of the <DRM Colour Table Group> instance.
