Rotates an image by the angle degrees in the % CCW direction. Degrees may be any number. % The function will put degrees in the range 0 % to 360 degrees and then into a range of -45 to 45 % degrees after performing elementary 90 degree rotations.(Rotates an image by the angle degrees in the % CCW direction.
