  • 2 minutes to read

Specifies the alpha fill mode for video processing.

Syntax

typedef enum D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE {
  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE,
  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_BACKGROUND,
  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_DESTINATION,
  D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM
} ;

Constants

D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_OPAQUE Alpha values inside the target rectangle are set to opaque.
D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_BACKGROUND Alpha values inside the target rectangle are set to the alpha value specified in the background color. To set the background color, call the VideoProcessorSetOutputBackgroundColor function.
D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_DESTINATION Existing alpha values remain unchanged in the output surface.
D3D11_1DDI_VIDEO_PROCESSOR_ALPHA_FILL_MODE_SOURCE_STREAM 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 VideoProcessorSetOutputAlphaFillMode function.

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.
