Parameters

  • compositeMode
    Type: D2D1_COMPOSITE_MODE

Type: HRESULT

If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.

Remarks

An effect group applies to the rasterization of a visual subtree. The blending mode determines how that rasterization is blended back with the screen as part of applying the effect. By default, the rasterization is blended back with "source over" semantics; that is, the colors are blended with per-pixel transparency.
