ID3D11VideoContext::VideoProcessorSetOutputAlphaFillMode method

Sets the alpha fill mode for data that the video processor writes to the render target.

Syntax

C++


void VideoProcessorSetOutputAlphaFillMode(
  [in] ID3D11VideoProcessor                  *pVideoProcessor,
  [in] D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE AlphaFillMode,
  [in] UINT                                  StreamIndex
);

Parameters

pVideoProcessor [in]: A pointer to the ID3D11VideoProcessor interface. To get this pointer, call ID3D11VideoDevice::CreateVideoProcessor.
AlphaFillMode [in]: The alpha fill mode, specified as a D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE value.
StreamIndex [in]: The zero-based index of an input stream. This parameter is used if AlphaFillMode is D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM. Otherwise, the parameter is ignored.

Return value

This method does not return a value.

Remarks

To find out which fill modes the device supports, call the ID3D11VideoProcessorEnumerator::GetVideoProcessorCaps method. If the driver reports the D3D11_VIDEO_PROCESSOR_FEATURE_CAPS_ALPHA_FILL capability, the driver supports all of the fill modes. Otherwise, the AlphaFillMode parameter must be D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE.

The default fill mode is D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE.
