D3D12DDI_VIDEO_SIZE_RANGE_0032 structure (d3d12umddi.h)

The D3D12DDI_VIDEO_SIZE_RANGE_0032 structure describes a supported range of output sizes for a scaler.

Syntax

typedef struct D3D12DDI_VIDEO_SIZE_RANGE_0032 {
  UINT MaxWidth;
  UINT MaxHeight;
  UINT MinWidth;
  UINT MinHeight;
} D3D12DDI_VIDEO_SIZE_RANGE_0032;

Members

MaxWidth

The largest output Width that can be scaled to. The largest value allowed is D3D12_REQ_TEXTURE2D_U_OR_V_DIMENSION (16384).

MaxHeight

The largest output Height that can be scaled to. The largest value allowed is D3D12_REQ_TEXTURE2D_U_OR_V_DIMENSION (16384).

MinWidth

The smallest output Width that can be scaled to. The smallest allowed value is 1.

MinHeight

The smallest output Height that can be scaled to. The smallest allowed value is 1.

Remarks

By default, the supported range indicates all possible output size combinations that exist between the Max size and Min size for the extent, ScaleSupportFlags may add additional caveats.

When scaling is not supported, the Min and Max sizes should both be set to the input size and no flags specified.
