Property

Description

Class
  • <DRM HSV 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 HSV Colour>.

The hue_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 HSV Colour>'s hsv_data.hue field.

The saturation_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 HSV Colour>'s hsv_data.saturation field.

The value_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 HSV Colour>'s hsv_data.value 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 hsv_data. hue field value of the affected <DRM HSV Colour> instances. If the value is zero, the hsv_data. huefield of those instances is not controlled.

3 This value 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. saturationfield of those instances is not controlled.

4 This value 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. valuefield of those instances is not controlled.
