Sourceval create_rgb : ?alpha:bool -> ?max_val:int -> int -> int -> image

create_rgb ?alpha ?max_val width height is an RGB image of dimensions width * height. Raises Invalid_argument if width or height are negative, or if max_val is not in the range [1;65535].

Sourceval create_grey : ?alpha:bool -> ?max_val:int -> int -> int -> image

create_rgb ?alpha ?max_val width height is a greyscale image of dimensions width * height. Raises Invalid_argument if width or height are negative, or if max_val is not in the range [1;65535].
