IMPORT_C TRgb

ReferenceWhiteColorL

(

)

const

Gets the current rgb value of the reference white color

Specifies the white balance mode and the value of reference white color.

leave: KErrArgument The whitebalance mode is not in the TWhiteBalanceMode enumeration

TWhiteBalanceMode aWhiteBalanceMode	The white balance mode.
TRgb aReferenceWhiteColor	The rgb value of the reference white color.

(

)

const

Gets the white balance mode

Parameters to define the white balance modes.

EWhiteBalanceMeanMode	Uses the estimated mean gray for the color correction, which is the default mode.
EWhiteBalanceMaxMode	Uses the estimated maximum intensity color.
EWhiteBalanceManualMode	Uses a white reference color.
EWhiteBalanceClusterMode	Calulates the reference from the mean value of the 256-bin distribution.
