ARGUMENTSsrc, rY, gY, bY
FUNCTIONgapi_RGB2Gray1
RETURN TYPEGMat
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Resulting gray color value computed as

\texttt{dst} (I)= \texttt{rY} * \texttt{src}(I).R + \texttt{gY} * \texttt{src}(I).G  + \texttt{bY} * \texttt{src}(I).B

Note: Function textual ID is "org.opencv.imgproc.colorconvert.rgb2graycustom"

See: RGB2YUV

gapi_RGB2Gray1(src: GMat, rY: number, gY: number, bY: number): GMat;

rY

float multiplier for R channel.

gY

float multiplier for G channel.
