D3D12_VIDEO_PROCESS_FILTER_RANGE structure (d3d12video.h)
Defines the range of supported values for an image filter.
Syntax
typedef struct D3D12_VIDEO_PROCESS_FILTER_RANGE {
INT Minimum;
INT Maximum;
INT Default;
FLOAT Multiplier;
} D3D12_VIDEO_PROCESS_FILTER_RANGE;
Members
Minimum
The minimum value of the filter.
Maximum
The maximum value of the filter.
Default
The default value of the filter.
Multiplier
A multiplier. Use the following formula to translate the filter setting into the actual filter value:
Actual Value = Set Value × Multiplier.
Remarks
The multiplier enables the filter range to have a fractional step value. For example, a hue filter might have an actual range of [–180.0 ... +180.0] with a step size of 0.25. The device would report the following range and multiplier:
- Minimum: –720
- Maximum: +720
- Multiplier: 0.25
In this case, a filter value of 2 would be interpreted by the device as 0.50 (or 2 × 0.25).
The device should use a multiplier that can be represented exactly as a base-2 fraction.
