Fader.FadeOutVolumeCurveSetEx method

Previous pageReturn to chapter overviewNext page

Remarks

 

Sets the volume curve for fade-out operations.

 

This setting is lost after invoking the Fader.Exit method so you should call again this method after a new eventual call to the Fader.Init method.

 

 

Syntax

 

[Visual Basic]

control.Fader.FadeOutVolumeCurveSetEx (

nCurveType as enumVolumeCurves,

nLeftX as Integer,

nLeftY as Integer,

nRightX as Integer,

nRightY as Integer

) as enumErrorCodes


 

[C++]

short control.Fader.FadeOutVolumeCurveSetEx (

short nCurveType,

short nLeftX,

short nLeftY,

short nRightX,

short nRightY

);

amp3dj_i000091

VOLUME_CURVE_COSINE

Cosine curve

amp3dj_i000092

VOLUME_CURVE_SMOOTH

4

Smooth curve

amp3dj_i000093

VOLUME_CURVE_CUSTOM

5

Custom Bézier curve.

amp3dj_i000094

nLeftX

The horizontal position, expressed in percentage of the custom curve designer's area, of the left control point (*). This parameter is ignored if the nScaleType parameter above has been set to a value different from VOLUME_CURVE_CUSTOM.

nLeftY

The vertical position, expressed in percentage of the custom curve designer's area, of the left control point (*). This parameter is ignored if the nScaleType parameter above has been set to a value different from VOLUME_CURVE_CUSTOM.

nRightX

The horizontal position, expressed in percentage of the custom curve designer's area, of the right control point (*). This parameter is ignored if the nScaleType parameter above has been set to a value different from VOLUME_CURVE_CUSTOM.

nRightY

The vertical position, expressed in percentage of the custom curve designer's area, of the right control point (*). This parameter is ignored if the nScaleType parameter above has been set to a value different from VOLUME_CURVE_CUSTOM.

 

 

(*) The custom curve designer manages a windowed control, whose visual aspect can be defined programmatically, which allows designing volume curves based upon Bézier curves whose shape is defined through the manual positioning of 2 control points (displayed in cyan color on the graphic below). For further information about the use of the embedded CurveDesigner refer to the tutorial How to create custom volume curves.
