ARGUMENTSsrc, dst, gainB, gainG
FUNCTIONxphoto_applyChannelGains
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Implements an efficient fixed-point approximation for applying channel gains, which is the last step of multiple white balance algorithms.

xphoto_applyChannelGains(src: Mat, dst: Mat, gainB: number, gainG: number, gainR: number): void;
src

Input three-channel image in the BGR color space (either CV_8UC3 or CV_16UC3)

dst

Output destination, filled by the native operation. Output image of the same size and type as src.

gainB

gain for the B channel

gainG

gain for the G channel

gainR

gain for the R channel
