D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE enumeration (d3d11.h)

  • Article

Specifies the alpha fill mode for video processing.

Syntax

typedef enum D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE {
  D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE = 0,
  D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_BACKGROUND = 1,
  D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_DESTINATION = 2,
  D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM = 3
} ;

Constants

 
D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE
Value: 0
Alpha values inside the target rectangle are set to opaque.
D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_BACKGROUND
Value: 1
Alpha values inside the target rectangle are set to the alpha value specified in the background color. To set the background color, call the ID3D11VideoContext::VideoProcessorSetOutputBackgroundColor method.
D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_DESTINATION
Value: 2
Existing alpha values remain unchanged in the output surface.
D3D11_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM
Value: 3
Alpha values are taken from an input stream, scaled, and copied to the corresponding destination rectangle for that stream. The input stream is specified in the StreamIndex parameter of the ID3D11VideoContext::VideoProcessorSetOutputAlphaFillMode method.

If the input stream does not have alpha data, the video processor sets the alpha values in the target rectangle to opaque. If the input stream is disabled or the source rectangle is empty, the alpha values in the target rectangle are not modified.
