VMR9AlphaBitmapFlags Enumeration

The VMR9AlphaBitmapFlags enumeration type defines the possible values for the dwFlags member of the VMR9AlphaBitmap structure.

Syntax

typedef enum VMR9AlphaBitmapFlags{
  VMR9AlphaBitmap_Disable  = 0x00000001,
  VMR9AlphaBitmap_hDC  = 0x00000002,
  VMR9AlphaBitmap_EntireDDS  = 0x00000004,
  VMR9AlphaBitmap_SrcColorKey  = 0x00000008,
  VMR9AlphaBitmap_SrcRect  = 0x00000010,
  VMR9AlphaBitmap_FilterMode  = 0x00000020
};

Members

VMR9AlphaBitmap_Disable

Disable the alpha bitmap. This flag cannot be combined with any other flags.

VMR9AlphaBitmap_hDC

The bitmap is specified as a GDI device context (HDC) in the hdc member of the VMR9AlphaBitmap structure. If this flag is not present, the bitmap is specified as a Direct3D IDirect3DSurface9 pointer in the pDDS member of the structure.

VMR9AlphaBitmap_EntireDDS

Use the entire Direct3D surface. The rSrc member of the VMR9AlphaBitmap structure is ignored. This flag cannot be combined with the VMR9AlphaBitmap_hDC flag.

VMR9AlphaBitmap_SrcColorKey

Indicates that the srcClrKey member is valid and should be used when blending. This flag cannot be used with a Direct3D surface that contains per-pixel alpha (D3DFMT_A8R8G8B8 format).

VMR9AlphaBitmap_SrcRect

Indicates that the rSrc member is valid and specifies a sub-rectangle of the original image to be blended. This flag is only valid for the IVMRMixerBitmap9::UpdateAlphaBitmapParameters method.

VMR9AlphaBitmap_FilterMode

Indicates that the dwFilterMode member is valid and should be used to overide the VMR filter's default filtering method.
