VMR9ProcAmpControlRange structure

The VMR9ProcAmpControlRange structure specifies the valid range for an image adjustment property. The range depends on the graphics device driver. This structure is used with the Video Mixing Renderer 9 Filter (VMR-9).

Syntax


typedef struct _VMR9ProcAmpControlRange {
  DWORD                   dwSize;
  VMR9ProcAmpControlFlags dwProperty;
  float                   MinValue;
  float                   MaxValue;
  float                   DefaultValue;
  float                   StepSize;
} VMR9ProcAmpControlRange;

Members

dwSize

Size of the structure, in bytes. The value must be sizeof(VMR9ProcAmpControlRange).

dwProperty

Specifies the image adjustment property to query, as a member of the VMR9ProcAmpControlFlags enumeration. The caller should set this field.

MinValue

Specifies the minimum value for the property. The driver sets this field.

MaxValue

Specifies the maximum value for the property. The driver sets this field.

DefaultValue

Specifies the default value for the property. The default value is the value that does not alter the image. The driver sets this field.

StepSize

Specifies the valid increments from MinValue to MaxValue. The driver sets this field.
