D3D11_1DDI_VIDEO_PROCESSOR_FILTER_RANGE structure

Description

Defines the range of supported values for an image filter.

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 Ã— 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 Ã— 0.25).

The device should use a multiplier that can be represented exactly as a base-2 fraction.
