DCOMPOSITION_COMPOSITE_MODE enumeration

The mode to use to blend the bitmap content of a visual with the render target.

Syntax

typedef enum _DCOMPOSITION_COMPOSITE_MODE { 
  DCOMPOSITION_COMPOSITE_MODE_SOURCE_OVER         = 0,
  DCOMPOSITION_COMPOSITE_MODE_DESTINATION_INVERT  = 1,
  DCOMPOSITION_COMPOSITE_MODE_MIN_BLEND           = 2,
  DCOMPOSITION_COMPOSITE_MODE_INHERIT             = 0xffffffff
} DCOMPOSITION_COMPOSITE_MODE;

Constants

DCOMPOSITION_COMPOSITE_MODE_SOURCE_OVER

The standard source-over-destination blend mode.

DCOMPOSITION_COMPOSITE_MODE_DESTINATION_INVERT

The bitmap colors are inverted.

DCOMPOSITION_COMPOSITE_MODE_MIN_BLEND

Bitmap colors subtract for color channels in the background.

DCOMPOSITION_COMPOSITE_MODE_INHERIT

Bitmaps are blended according to the mode established by the parent visual.

Remarks

A single visual can have any combination of visual properties. However, if a visual has the following combination of properties, the borders of the visual will default to DCOMPOSITION_BORDER_MODE_HARD.

• SetCompositeMode(DCOMPOSITION_COMPOSITE_MODE_DESTINATION_INVERT)
• SetBorderMode(DCOMPOSITION_BORDER_MODE_SOFT)
• SetBitmapInterpolationMode(DCOMPOSITION_BITMAP_INTERPOLATION_MODE_NEAREST_NEIGHBOR)

If you want a visual to be drawn with antialiasing, use DCOMPOSITION_BITMAP_INTERPOLATION_MODE_LINEAR for the content of the visual, and DCOMPOSITION_BORDER_MODE_SOFT for the edges.
