D3D11_VIDEO_PROCESSOR_FILTER_RANGE structure

Defines the range of supported values for an image filter.

Syntax

typedef struct _D3D11_VIDEO_PROCESSOR_FILTER_RANGE {
  int   Minimum;
  int   Maximum;
  int   Default;
  float Multiplier;
} D3D11_VIDEO_PROCESSOR_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.
