APPENDIX A - Classes HSV Colour Control Link |
|---|
The specialized <Control Link> used to provide the connection between an ordered aggregation of <Expressions> and the target fields of an <HSV Colour>.
The hue_expr_index field is a 1-based index into the ordered aggregation of <Expressions>, and is used to select the specific <Expression> that controls the value of <HSV Colour>'s hsv_data.hue field.
The saturation_expr_index field is a 1-based index into the ordered aggregation of <Expressions>, and is used to select the specific <Expression> that controls the value of <HSV Colour>'s hsv_data.saturation field.
The value_expr_index field is a 1-based index into the ordered aggregation of <Expressions>, and is used to select the specific <Expression> that controls the value of <HSV Colour>'s hsv_data.value field.
See the example for <CMY Colour Control Link>, which is analogous to how this class is used.

This is a text description of the given <Control Link> instance's purpose.
This value specifies which <Expression> component, if any, controls the hue field value of the affected <HSV Colour> instances. If the value is zero, the hue field of those instances is not controlled.
This value specifies which <Expression> component, if any, controls the saturation field value of the affected <HSV Colour> instances. If the value is zero, the saturation field of those instances is not controlled.
This value specifies which <Expression> component, if any, controls the value field value of the affected <HSV Colour> instances. If the value is zero, the value field of those instances is not controlled.
