DCOMPOSITION_OPACITY_MODE enumeration (dcomptypes.h)

Specifies how the effective opacity value of a visual is applied to that visual’s content and children.

Syntax

typedef enum DCOMPOSITION_OPACITY_MODE {
  DCOMPOSITION_OPACITY_MODE_LAYER = 0,
  DCOMPOSITION_OPACITY_MODE_MULTIPLY = 1,
  DCOMPOSITION_OPACITY_MODE_INHERIT = 0xffffffff
} ;

Constants

 
DCOMPOSITION_OPACITY_MODE_LAYER
Value: 0
The target visual defines a logical layer into which its entire sub-tree is composed with a starting effective opacity of 1.0. The original opacity value is then used to blend the layer onto the visual’s background.
DCOMPOSITION_OPACITY_MODE_MULTIPLY
Value: 1
The opacity value is multiplied with the effective opacity of the parent visual and the result is then individually applied to each piece of content in this visual’s sub-tree.
DCOMPOSITION_OPACITY_MODE_INHERIT
Value: 0xffffffff
The opacity mode is the same as that of the target visual’s parent visual.
