Property

Description

Class
  • <DRM RGB Colour Control Link>

Superclass

Subclass
  • None.

Definition

The specialized <DRM Control Link> used to provide the connection between an ordered aggregation of <DRM Expressions> and the target fields of an <DRM RGB Colour>.

The red_expr_index field is a 1-based index into the ordered aggregation of <DRM Expressions>, and is used to select the specific <DRM Expression> that controls the value of <DRM RGB Colour>'s rgb_data.red field.

The green_expr_index field is a 1-based index into the ordered aggregation of <DRM Expressions>, and is used to select the specific <DRM Expression> that controls the value of <DRM RGB Colour>'s rgb_data.green field.

The blue_expr_index field is a 1-based index into the ordered aggregation of <DRM Expressions>, and is used to select the specific <DRM Expression> that controls the value of <DRM RGB Colour>'s rgb_data.blue field.

Clarifications

1 This is a text description of the given <DRM Control Link> instance's purpose.

2 This value specifies which <DRM Expression> component, if any, controls the rgb_data. red field value of the affected <DRM RGB Colour> instances. If the value is zero, the rgb_data. redfield of those instances is not controlled.

3 This value specifies which <DRM Expression> component, if any, controls the rgb_data. green field value of the affected <DRM RGB Colour> instances. If the value is zero, the rgb_data. greenfield of those instances is not controlled.

4 This value specifies which <DRM Expression> component, if any, controls the rgb_data. blue field value of the affected <DRM RGB Colour> instances. If the value is zero, the rgb_data. bluefield of those instances is not controlled.
