Syntax

typedef struct __MIDL___MIDL_itf_mfidl_0000_0136_0002 {
  LONG minValue;
  LONG maxValue;
  LONG stepValue;
  LONG defaultValue;
} MF_CAMERA_CONTROL_RANGE_INFO;

Members

minValue

The minimum value supported by the control.

maxValue

The maximum value supported by the control.

stepValue

The incremental step value supported by the control.

defaultValue

The default value for the control.

Remarks

The legacy PROPSETID_VIDCAP_VIDEOPROCAMP and PROPSETID_VIDCAP_CAMERACONTROL control sets provide an allowed range and step value of with which a control can be configured, as well as a default value. For other controls, the caller is responsible for knowing whether the underlying control supports the basic range information.

Retrieve the range information for a control by calling IMFCameraControlDefaults::GetRangeInfo.
