RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Given an original color image, two differently colored versions of this image can be mixed seamlessly.

colorChange(src: Mat, mask: Mat, dst: Mat, red_mul: number, green_mul: number, blue_mul: number): void;
