Syntax

 

[Visual Basic]

Public Function VolumeAutomationPointSetParameters (

nIndexVolumePoint as Int32,

fPosition as float,

fVolumeLevel as float,

nCurveType as enumVolumeCurves

) as enumErrorCodes


 

[C#]

public enumErrorCodes VolumeAutomationPointSetParameters (

Int32 nIndexVolumePoint,

float fPosition,

float fVolumeLevel,

enumVolumeCurves nCurveType

);


 

[C++]

public: enumErrorCodes VolumeAutomationPointSetParameters (

Int32 nIndexVolumePoint,

float fPosition,

float fVolumeLevel,

enumVolumeCurves nCurveType

);


 

 

Parameter

Description

 

 

nIndexVolumePoint

Zero-based index of the volume point

fPosition

Position, expressed in the unit set through the Effects.VolumeAutomationSetScales method, where the volume point will be applied

fVolumeLevel

Volume applied starting from the current automation point: the value is expressed in the unit set through the Effects.VolumeAutomationSetScales method.

nCurveType

Type of curve applied to reach the next volume point.

Supported values are the following:

Mnemonic constant

Value

Meaning

 

 

 

VOLUME_CURVE_NONE

0

No curve is applied: volume will be changed immediately and will be kept till next volume point.

VOLUME_CURVE_LINEAR

1

Linear curve

VOLUME_CURVE_EXPONENTIAL

2

Exponential curve

VOLUME_CURVE_COSINE

3

Cosine curve

VOLUME_CURVE_SMOOTH

4

Smooth curve

VOLUME_CURVE_CUSTOM

5

Custom Bézier curve.

 

 

Return value
